The yakuza have resorted to stealing Pokemon cards. Japan is worried about the next generation of gangsters

Tokuryu are anonymous gangsters and tech-savvy young people hired for specific jobs

A senior member of the infamous Japanese yakuza gang was arrested for allegedly stealing Pokemon cards near Tokyo in April.

The case has been seen as an example of Japanese crime groups struggling with declining membership and resorting to petty criminal behaviour.


Police agents who were busy dealing with thousands of yakuza members just a few years ago have noticed something new: unorganized and loosely connected groups they believe are behind a series of crimes once dominated by yakuza.


Police call them “tokuryu,” anonymous gangsters and tech-savvy young people hired for specific jobs. They often cooperate with yakuza, obscuring the boundary between them and making police investigations more difficult, experts and authorities say.

The Tokyo metropolitan police are currently investigating six suspects in their 20s and 30s, most of them without connections to one another, who are believed to have been hired on social media to kill, transport and burn the bodies of an older couple at a riverbank of Nasu, 200 kilometers (124 miles) northeast of Tokyo.

“It’s a crime carried out like a part-time job,” Taihei Ogawa, a former police investigator and crime analyst, said on an online talk show. “Tasks are divided, making it difficult for police to track down where instructions come from.”

The yakuza membership has shrunk to 20,400 last year, one-third what it was two decades ago, according to the National Police Agency. It attributed the decline largely to legislation passed to combat organized crime that includes measures like barring members of designated groups from opening bank accounts, renting apartments, buying cell phones or insurance.

Yakuza once operated from well-marked offices, often with signs out front and symbols of their trade such as lanterns and samurai swords visible through the windows. They were often portrayed in films and cartoons as noble outlaws with a code of honor. Their typical rackets were extortion, gambling, prostitution, gunrunning, drug trafficking and construction kickbacks.

But gang violence in a number of neighborhoods, including the 2007 fatal shooting of Nagasaki Mayor Iccho Ito during his election campaign, have since led the government to tighten gun control, racketeering laws and other anti-gang measures.


Local residents and businesses have also stepped up and filed dozens of lawsuits against yakuza groups to bar them from their communities. In December 2022, Fukuoka city filed for a court injunction to close down an office led by the Kobe Yamaguchi-gumi branch of yakuza near elementary and junior high schools and forced it off the street six months later.

The aging of yakuza members and their financial difficulties have also hobbled the syndicate, experts say.

The number of arrested yakuza members in 2023 declined to 9,610, compared to 22,495 in 2014, according to the police.

Yakuza crackdowns have driven many members to quit and sent others underground. But they also prompted younger generations to join “tokuryu” groups rather than the traditional criminal structures, Noboru Suetomi, a criminologist and expert on yakuza, said in his recent article.


The National Police Agency describes “tokuryu” as “anonymous and fluid” groups that repeatedly form and disband via social media to carry out swindling, illegal betting, prostitution and other crimes often remotely, including from overseas.

They recruit a number of participants who are not connected to each other and assign them specific roles. While often cooperating with conventional yakuza, they invest their earnings into illegal businesses, the agency said. “They have become a threat to public safety."

While numbers are hard to track, more than 10,000 people were arrested from 2021 to 2023 for alleged swindling, illegal drug trade other crimes, such as forgery of identification cards, which were linked to “tokuryu,” records show.

In April 2022, police busted a ring of 19 people recruited anonymously who operated a fake telecom company out of Cambodia and swindled an elderly Japanese. In 2023, Tokyo police arrested six people who got in touch via social media and carried out a high-profile daytime robbery of watches and jewelry worth 300 million yen ($1.92 million) at a store in Tokyo’s posh Ginza district.

National Police chief Yasuhiro Tsuyuki, at a meeting Monday of top prefectural criminal investigators, said “tokuryu” have been part of surging cases of swindling via social media and have become a “serious concern.” He urged police across the country to make unified efforts to tackle the problem and also cooperate with authorities abroad.


Tsuyuki has said police must drastically change their anti-organized crime measures to keep up with the new menace, calling for organizational restructuring and cooperation across investigative departments, from cyber to robbery and fraud.

To reinforce measures, the police in April launched a joint investigation unit specializing in social media and telephone scams. The agency also stepped up policing in entertainment districts and measures against juvenile delinquents and motorcycle gangs.



Quakes Do Not Kill People, Bad Buildings Do

Infrastructure surge in the geologically fragile Himalayas


 

By Ranjit Devraj

Early on Tuesday (April 23), Taiwan was hit by a series of earthquakes with the highest magnitude at 6.3. The latest tremor came less than three weeks after a magnitude 7.4 quake hit the island, damaging over 100 buildings and trapping dozens of people in collapsed tunnels

If an equally strong earthquake were to hit the tectonically unstable Himalayas, an even bigger catastrophe awaits with some 700 million people living along this gigantic fault line, an arc stretching from Afghanistan to Burma and taking in Bangladesh, Bhutan, Nepal, India and Tibet.

The Himalayas, which separate Asian giants India and China, were created about 45 to 50 million years ago when the Indian Plate collided with the Eurasian Plate to push up the world’s highest mountain range featuring Everest and K2.

“Earthquakes in the Himalayas pose a grave danger to thickly populated settlements in the alluvial plains of North India,” says C.P. Rajendran, adjunct professor at the National Institute of Advanced Studies, in Bangalore, India.

“Considering the current level of infrastructure and human activities in the region, the threat of earthquakes is of serious social and economic concern.”

Rajendran, an author of ‘The Rumbling Earth’, a newly released book on earthquakes on the sub-continent, warns that tunneling and road-building in the fragile Himalayas should be limited. It takes lessons from the 2015 Nepal quake which resulted in massive loss of infrastructure, as well as claiming 9,000 lives.

In November 2023, the Silkyara Bend-Barkot road tunnel being built in Uttarkashi, an important Hindu religious pilgrimage destination, collapsed. Rajendran said the tunnel was too close to the main tectonic fault line where the Indian plate had collided with the Eurasian plate.

The Nepal quake and the even more severe one that hit Pakistan’s Kashmir region in 2005 that killed more than 80,000 people indicate the need for preparedness. Rajendran says that while short-term predictions of quakes are not yet possible, their effects can be predicted and pragmatic measures such as seismically-sound building codes must be enforced.

The Rumbling Earth emphasises the need to enforce building codes in the densely-populated Indo-Gangetic Plains, a large bowl of alluvial sediment dotted with cities and towns powered by hydroelectric dams as well as thermal and nuclear power plants.

What drives the frenetic road and infrastructure building in the Himalayas?

Apart from popular measures to make it easier for Hindu pilgrimages to reach the so-called “abode of the gods” in the high mountains, there are strategic considerations along the disputed borders that India shares with China.

India and China are “locked in a frenzied infrastructure-building competition,” according to Aleksandra Gadzala Tirziu, founder and CEO of the geopolitical and strategic cosmmunications firm, Magpie Advisory.

“The buildup suggests both sides have strategically decided to leverage peacetime to bolster their logistical capabilities for a potential war,” she writes in an article for the independent Liechtenstein-based Geopolitical Intelligence Services.

However, the issue of frenzied building activity in quake-prone zones is not exclusive to the Himalayas.

Safety non-compliance

Across the Asia Pacific region infrastructure and homes are rising up in seismically sensitive areas with governments seemingly reluctant to enforce safety codes for fear of slowing down development activity.

For example, a recent study conducted by the Philippine Institute of Volcanology and Seismology and the Tokyo Institute of Technology on 100 high-rise buildings in Metro Manila and Cebu found several of them failed to conform to the national building code.

The Philippines falls in the ‘Ring of Fire’ around the Pacific Ocean rim which is marked by volcanic activity and seismic events as a result of overlapping tectonic plates. It includes Indonesia, Japan, the western seaboard of North America and Chile.

Studies of the Lombok and Plau quakes that hit Indonesia in 2018 showed that much of the damage caused to buildings and infrastructure was due to noncompliance with concrete reinforcement specifications.

A highly active faultline is the Great Sumatran Fault which, in 2004, generated a 9.3 magnitude earthquake and the Indian Ocean tsunami resulting in over 226,000 deaths and incalculable damage to infrastructure in Indonesia, Thailand, Sri Lanka and India, catching large populations and their governments unprepared.

In contrast, the September 2015 earthquake and tsunami that struck the central coast of Chile only caused 13 deaths. Chile and Japan are countries on the Ring of Fire where there are strict building codes and tall structures must be made to sway with seismic waves, rather than remain rigid.

If there is one lesson to be learned from past experiences of seismic events it is that, far more than quakes, it is poorly constructed buildings that kill people. Governments in the region must develop and enforce the necessary building regulations to prevent possible massive loss of life.

China launches anti-dumping probe into EU, US, Japan, Taiwan plastics

BEIJING —

China's commerce ministry on Sunday launched an anti-dumping probe into POM copolymers, a type of engineering plastic, imported from the European Union, United States, Japan and Taiwan.

The plastics can partially replace metals such as copper and zinc and have various applications including in auto parts, electronics, and medical equipment, the ministry said in a statement.

The investigation should be completed in a year but could be extended for six months, it said.

The European Commission, which oversees EU trade policy, said it would carefully study the contents of the investigation before deciding on any next steps.

"We expect China to ensure that this investigation is fully in line with all relevant WTO (World Trade Organization) rules and obligations," a spokesperson said.

China's plastics probe comes amid a broader trade row with the United States and Europe.

The United States on Tuesday unveiled steep tariff increases on Chinese electric vehicles, or EVs, computer chips, medical products and other imports.

On Friday, the European Union launched a trade investigation into Chinese tinplate steel, the latest in a string of EU trade and subsidy probes into Chinese exports.

Most notably, the European Commission launched a probe last September to decide whether to impose punitive tariffs on cheaper Chinese EVs that it suspects of benefiting from state subsidies.

Beijing argues the recent focus by the United States and Europe on the risks to other economies from China's excess capacity is misguided.

Chinese officials say the criticism understates innovation by Chinese companies in key industries and overstates the importance of state support in driving their growth.
Japan proposes expanding commercial whaling to fin whales, a larger species than the 3 allowed now

TOKYO (AP) — Japan’s Fisheries Agency has proposed expanding commercial whaling along the country’s coast to fin whales, a larger species than the three currently permitted.

The proposal comes five years after Japan resumed commercial whaling within its exclusive economic zone after withdrawing from the International Whaling Commission in 2019. It ended 30 years of what Japan called “research whaling” that had been criticized by conservationists as a cover for commercial hunts banned by the commission in 1988.

Chief Cabinet Secretary Yoshimasa Hayashi, whose electoral district is traditionally known for whaling, said Thursday the government supports sustainable use of whales as part of Japan’s traditional food culture and plans to promote the industry.

“Whales are an important food resource and we believe they should be sustainably utilized just like any other marine resources, based on scientific evidence,” Hayashi told reporters. “It is also important to carry on Japan’s traditional food culture.”

The Fisheries Agency said it is seeking public comments until June 5 on the proposed plan and will seek its approval at the next review meeting in mid-June.

The agency decided to propose adding fin whales to the allowable catch list after stock surveys confirmed a sufficient recovery of the fin whale population in the North Pacific.

The plan is not meant to increase whale meat supply and whalers who catch fin whales do not necessarily have to meet a quota, an agency official said, speaking on condition of anonymity to discuss the issue. For this year, the agency has set a combined catch quota of 379 for the three other whale species.

Last year, Japanese whalers caught 294 minke, Bryde’s and sei whales — less than 80% of the quota and fewer than the number once hunted in the Antarctic and the northwestern Pacific under the research program.

Japan’s whaling has long been a source of controversy and attacks from conservationists, but anti-whaling protests have largely subsided after Japan terminated its much-criticized Antarctic research hunts in 2019 and returned to commercial whaling limited to Japanese waters.

Whale meat consumption in Japan was an affordable source of protein during the malnourished years after World War II, with annual consumption peaking at 233,000 tons in 1962. However, whale was quickly replaced by other meats and supply has since fallen to around 2,000 tons in recent years, according to Fisheries Agency statistics.

Japanese officials want to increase that to about 5,000 tons, to keep the industry afloat.

On a visit to the former Tsukiji fish market area in downtown Tokyo, Yuuka Fujikawa from Hokkaido, said she has hardly seen whale meat sold at supermarkets. “I’ve actually never tried it myself,” she said.

“I want more people to appreciate the taste of whale,” said Hideyuki Saito, from neighboring Saitama prefecture. “I want it to be more popularized.”

Carlos Sempere Santos, a 28-year-old tourist from Spain, said he couldn’t imagine eating whale as whales are special and smart animals.

Shirley Bosworth from Australia said she opposes whaling because whales “should be protected.” Whales often get beached in Australia, where people unite to try and “push them back in the sea.”

A whaling operator Kyodo Senpaku Co. last year launched whale meat vending machines. The company also completed construction of its new 7.5 billion yen ($48 million) Kangei Maru — a 9,300-ton mother ship — and pledges to use it for sustainable commercial whaling.

More women on hospital teams mean better surgery outcomes



OXFORD UNIVERSITY PRESS USA

A new paper in the British Journal of Surgery, published by Oxford University Press, finds that care in hospitals with higher surgery team sex-diversity was associated with better post-operative outcomes for patients.

In various industries, including business, finance, technology, education, and the law, many observers believe gender and sex-diversity is important not only for equity, but also because it enriches the output of teams because members of the team bring a variety of experiences and viewpoints to their jobs. However, there is limited evidence for the value of teams’ sex-diversity in healthcare. Most published reports have focused on individuals’ characteristics and their associations with outcomes (e.g. how female patients respond to female physicians). There is limited data regarding the role sex diversity on healthcare teams and their outcomes.

Team sex-diversity likely contributes to patient outcomes through the many differences that male and female doctors bring to the workplace. Both sexes possess different skills, knowledge, experiences, beliefs, values, and leadership styles. Despite the benefits of sex and gender diversity on team performance, female doctors in operating rooms remain uncommon. The number of female anesthesiologists and surgeons have increased by only 5% over 10 years.

Researchers here conducted population-based retrospective cohort study using administrative healthcare data in Ontario, Canada, where 14 million residents receive health services through a government-administered single-payer system. The researchers investigated adult patients who had major elective inpatient surgeries between 2009 and 2019 to measure postoperative major morbidity. They found that of 709,899 surgeries performed at 88 hospitals during the period, 90-day major morbidity occurred in 14.4%. The median proportion of female anesthesiologists and surgeons per hospital per year was 28%. Overall, female surgeons performed 47,874 (6.7%) of surgeries. Female anesthesiologists treated patients in 192,144 (27.0%) of operations.

The study that hospitals with more than 35% female surgeons and anesthesiologists had better postoperative outcomes. Operations in such hospitals were associated with a 3% reduction in the odds of 90-day postoperative major morbidity in patients. The researchers note that the 35% threshold that they observed echoed findings from research in other industries in various countries, including the United States, Italy, Australia, and Japan, that also showed better outcomes once teams had 35% female members,

“These results are the start of an important shift in understanding the way in which diversity contributes to quality in perioperative care,” said the paper’s lead author, Julie Hallet. “Ensuring a critical mass of female anesthesiologists and surgeons in operative teams isn’t just about equity; it seems necessary to optimize performance. We wanted to challenge the binary discourse of comparing female and male clinicians and rather highlight the importance of diversity as a team asset or bonus in enhancing quality care. Ensuring sex-diversity in operative teams will require intentional effort to ensure systematic recruitment and retainment policies for female physicians, structural interventions such as minimum representation on teams, and monitoring and reporting of teams’ composition to build accountability in existing systems.”

The paper, “The association between anesthesiology-surgery team sex-diversity and major morbidity,” is available (on May 15th) at https://academic.oup.com/bjs/article-lookup/doi/10.1093/bjs/znae097.

While ethanol in alcoholic beverages impairs drinkers’ motor functions, it is that same substance that can power motor vehicles in a cleaner, more sustainable manner. What is necessary for the production of ethanol is yeast, but ethanol is among the environmental factors that add stress to yeasts, hindering their growth. To promote efficient bioethanol production, scientists have been searching for substances that can help yeasts better withstand ethanol, but few effective ones have been found.

An Osaka Metropolitan University research team, including graduate student Ilhamzah and Professor Ken-ichi Fujita of the Graduate School of Science and Professor Akira Ogita of the Research Center for Urban Health and Sports, has found that tannin from persimmons improves the growth of the yeast strain Saccharomyces cerevisiae in the presence of ethanol.

“In this study, yeast cultures grown in a medium containing ethanol and persimmon tannin showed an 8.9-fold increase in cell number compared to cultures grown in an ethanol medium without persimmon tannin,” stated Professor Fujita.

The researchers explored persimmon tannin because it is known for its antioxidative properties.

“Persimmon tannin reduced ethanol-induced oxidative stress,” Fujita added. “However, persimmon tannin did not prevent ethanol-induced cell membrane damage. This indicates the potential of persimmon tannin as a protective agent to enhance the yeast’s tolerance to ethanol stress by limiting oxidative damage, rather than limiting damage to the yeast’s cell membranes.”

The findings were published in the Journal of the Science of Food and Agriculture.

Thirteen years after the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (FDNPP), a breakthrough in analysis has permitted a world first: direct imaging of radioactive cesium (Cs) atoms in environmental samples.

The groundbreaking analysis, completed by a team of researchers in Japan, Finland, America, and France, analyzing materials emitted from the damaged FDNPP reactors, reveals important insights into the lingering environmental and radioactive waste management challenges faced in Japan. The study, titled ““Invisible” radioactive cesium atoms revealed: Pollucite inclusion in cesium-rich microparticles (CsMPs) from the Fukushima Daiichi Nuclear Power Plant” has just been published in the Journal of Hazardous Materials. It can be accessed here for free.

The Fukushima Daiichi Meltdowns: A Continuing Engineering and Environmental Puzzle

In 2011, after the Great Tōhoku Earthquake and Tsunami, 3 nuclear reactors at the FDNPP underwent meltdowns due to a loss of back-up power and cooling. Since then, extensive research efforts have focused on understanding the properties of fuel debris (the mixture of melted nuclear fuels and structural materials), found within the damaged reactors. That debris must be carefully removed and disposed of.

However, many uncertainties remain concerning the physical and chemical state of the fuel debris and this greatly complicates retrieval efforts.

Attempts to Understand the Chemistry of Radioactive Cesium Results in a World First

A significant amount of radioactive Cs was released from the damaged Fukushima Daiichi reactors in particulate form. The particles, termed Cs-rich microparticles (CsMPs), are poorly soluble, small (< 5 µm) and have a glass-like composition.

Prof. Satoshi Utsunomiya from Kyushu University, Japan, led the current study. He explained that the CsMPs “formed in the bottom of the damaged reactors during the meltdowns, when molten nuclear fuel impacted concrete.”

After formation, many CsMPs were lost from the reactor containment into the surrounding environment.

Detailed characterization of CsMPs has revealed important clues about the mechanisms and extent of the meltdowns. However, despite abundant Cs in the microparticles, direct atomic scale imaging of radioactive Cs in the particles has proven impossible.

Prof. Gareth Law, a study collaborator from the University of Helsinki, explained that “this means we lack full information on the chemical form of Cs in the particles and fuel debris.”

Utsunomiya continued, “whilst Cs in the particles is present at reasonably high concentrations, it is often still too low for successful atomic scale imaging using advanced electron microscopy techniques. When Cs is found at a high enough concentration, we have found that the electron beam damages the sample, rendering resulting data useless”. However, in the team’s previous work using a state-of-the-art high-resolution high-angle annular dark-field scanning transmission electron microscope (HR-HAADF-STEM), they found inclusions of a mineral called pollucite (a zeolite) within CsMPs. Law explained that “in past analysis we showed that the iron-rich pollucite inclusions in the CsMPs contained >20 wt.% Cs. In nature, pollucite is generally aluminum-rich.

The pollucite in the CsMPs was clearly different to that in nature indicating it formed in the reactors.” Utsunomiya continued, “because we knew that most of the Cs in CsMPs is fission derived, we thought that analysis of the pollucite could yield the first ever direct images of radioactive Cs atoms”.

Zeolites can become amorphous when subjected to electron beam irradiation, but that damage is related to the composition of the zeolite, and the team found that some pollucite inclusions were stable in the electron beam.

Learning this and informed by modelling, the team set about pain-staking analysis that saw Utsunomiya, graduate student Kanako Miyazaki, and the team finally image radioactive Cs atoms.  

Utsunomiya explained:

“It was incredibly exciting to see the beautiful pattern of Cs atoms in the pollucite structure, where about half of the atoms in the image correspond to radioactive Cs.”

He continued: “this is first time humans have directly imaged radioactive Cs atoms in an environmental sample. Finding concentrations of radioactive Cs high enough in environmental samples that would permit direct imaging is unusual and presents safety issues. Whilst it was exciting to make a scientific world first image, at the same time it’s sad that this was only possible due to a nuclear accident.”

More than an Imaging Breakthrough

Utsunomiya emphasized that the study's findings are broader than mere imaging of radioactive Cs atoms: “Our work sheds light on pollucite formation and the likely heterogeneity of Cs distribution within the FDNPP reactors and the environment.”

Law further underscored relevance: “we unequivocally demonstrate a new Cs occurrence associated with the materials emitted from the FDNPP reactors. Finding Cs containing pollucite in CsMPs likely means it also remains in the damaged reactors; as such, its properties can now be considered in reactor decommissioning and waste management strategies.”

Collaborator Emeritus Prof. Bernd Grambow from Subatech, IMT Atlantique Nantes University, added that: “we should now also begin to consider the environmental behavior or Cs-pollucite and its possible impacts. It likely behaves differently to other forms of Cs fallout documented thus far. Also,the effect on human health might have to be considered. The chemical reactivity of pollucite in the environment and in body fluids is certainly different than that of other forms of deposited radioactive Cs”. Finally reflecting on the study's significance, Prof. Rod Ewing from Stanford University underscored the pressing need for continued research to inform debris removal strategies and environmental remediation: “yet again, we see that the pain-staking analytical efforts of international scientists really can unlock the mysteries of nuclear accidents, aiding long-term recovery efforts.”

The study, titled "Invisible radioactive cesium atoms revealed: Pollucite inclusion in cesium-rich microparticles (CsMPs) from the Fukushima Daiichi Nuclear Power Plant," is published in the Journal of Hazardous Materials. The work was supported by bilateral funding from the Japan Society for the Promotion of Science and the Research Council of Finland.

U.S. Democrats charge disrespect over Kenya leader snub at Congress

Agence France-Presse
May 18, 2024 

Kenyan President William Ruto speaks about recent floods during an address from State House in Nairobi on May 3, 2024 (AFP)

Lawmakers from President Joe Biden's Democratic Party on Friday accused House Speaker Mike Johnson of disrespecting Africa after he did not invite Kenyan President William Ruto to address Congress during an upcoming Washington visit.

Biden has invited the key U.S. regional ally next week for a state visit -- the most prestigious trip a foreign leader can pay to Washington, which includes a ceremonial welcome and formal dinner at the White House.

Leaders on state visits often also address joint sessions of Congress, but Johnson, a Republican, brushed aside an appeal for an invitation to Ruto made by both the top Democrat and Republican on the House Foreign Affairs Committee.

In a letter to Johnson, 14 House Democrats told Johnson they were "extremely disappointed" by the decision and said, "The people of Kenya deserve more respect."

"Foreign adversaries like China, Russia and Iran are working tirelessly to subvert America's alliances, particularly in Africa," wrote the lawmakers including Gregory Meeks, the top Democrat on the House Foreign Affairs Committee.

"Your choice not to provide the Kenyan president, a key African partner, the opportunity to address the Congress helps create an opening for autocratic adversaries to make inroads in African public opinion."

Four foreign leaders have addressed joint sessions of the current Congress, in which the Republicans control the House -- the prime ministers of India and Japan and the presidents of Israel and South Korea.

"Failing to offer the same invitation to President Ruto risks sending the message that African partnerships are less valued by Congress," the Democratic lawmakers wrote.

The speaker's office did not immediately respond to a request for comment. The state visit comes as the US election season enters full swing, with many lawmakers occupied by campaigning.

Kenya has long been a close partner of the United States both economically and diplomatically and has partnered with Washington on security issues including in neighboring Somalia.

More recently, Kenya has volunteered to take the lead in a security mission aimed at stabilizing violence-ravaged Haiti, a relief for the United States after months of searching for a solution.

The last African leader to address Congress was Liberian president Ellen Johnson Sirleaf, the continent's first female elected head of state, in 2006.
North Korean-Iranian Military Cooperation Raises Alarm in the West

RFE/RL staff - May 15, 2024,

North Korea and Iran have a history of military cooperation, raising fears of technology sharing amid global tensions.

Western capitals are concerned about Iran acquiring advanced missile and nuclear technology from North Korea.

Allegations of North Korean weapons being used by Iranian proxies in recent conflicts have heightened suspicions.



Iran and North Korea have a long history of working together to advance their respective military arsenals.

Now, increased trade efforts between the two heavily sanctioned countries have raised concerns that they could share advanced missile and nuclear technology.

Coming at a time when Tehran and Pyongyang are playing a central role in heightened global tensions, the prospect of one pariah state in possession of nuclear weapons and intercontinental missiles, North Korea, aiding another accused of seeking those capabilities, Iran, has heightened fears in Western capitals.

The visit of a North Korean delegation to Tehran last month only served to increase suspicions.

Washington and Brussels both expressed concerns about any sanctions-violating cooperation, prompting Tehran to insist that the visit by North Korea’s external economic relations minister was aimed only at improving economic ties and assertions that it is seeking to expand cooperation on missile technology were "untrue."

But allegations that North Korean military technology has shown up in the hands of Iranian proxies in the Middle East and aided Iran's missile and drone attack against Israel last month have fueled concerns.

Experts say that the two sides are aligned in an anti-Western stance and most recently in supporting the Palestinian cause. And each has plenty to offer the other in terms of military expertise and experience.

"North Korea's nuclear program is obviously something that the Iranians seek to emulate," said Benjamin Young, a North Korea expert at Virginia Commonwealth University. "North Korea's ability to develop nuclear weapons at a rapid scale is admirable to the Islamic republic."

Pyongyang also has a long-range delivery vehicle in its Hwason-15 intercontinental ballistic missile, which is capable of carrying a heavy payload and of reaching the mainland United States.

"North Korea has made strides with very long-range-capable missiles, and that's something that Iran could be interested in," said Kenneth Katzman, a senior adviser for the New York-based Soufan Group intelligence consultancy and an expert on geopolitics in the Middle East.

Tehran has long insisted that its controversial nuclear program is only for peaceful purposes. But amid increased tensions with Israel, Iran has stressed, as recently as May 12, that it may have no choice but to change its nuclear doctrine.

As for what Tehran could offer North Korea, missile and drone attacks launched by Iran and its regional proxies have provided valuable experience.

Katzman noted that "Iranian missiles didn't do too well against Israel" in the April 19 strike, with most of the some 150 cruise and ballistic missiles having failed or been shot down. But he says the attack and others by Iran and its proxies in the region have given Tehran firsthand knowledge of how Western air-defense systems work.

This could be valuable to North Korea, he said, because its missiles "would be facing similar technology if launched against Japan, South Korea, the United States," the East Asian country's main adversaries.

Young says Iran's ability to mass produce Shahed-136 suicide drones, which were launched unsuccessfully by Iran against Israel but have been used extensively by Russia in its war against Ukraine, is also "likely attractive to Pyongyang."

North Korea has cultivated a military partnership with Tehran for decades, including the provision of conventional weapons to the Islamic republic during the Iran-Iraq War in the 1980s and help in the 1990s in developing Iranian ballistic missiles.

Successors to those missiles were used in Iran's attack against Israel, and South Korean intelligence is reportedly investigating whether North Korean components were used in the attack. South Korean intelligence has also said that North Korean weapons have been used against Israel by Hamas -- the U.S.- and EU-designated terrorist organization that sparked the war in Gaza with its deadly assault on Israel on October 7.

It is unclear when such weapons transfers may have been made, but Katzman said that since Israel launched its retaliatory and controversial invasion of Gaza with the aim of eliminating the Iran-backed Hamas, North Korea has "reiterated Iranian positions on Gaza as a means of standing with Iran."

Young says that Pyongyang's relationships with Iranian proxies are nothing new, noting that North Korea boasts some of the best tunnel-building experts in the world and "most likely" helped Lebanese Hizballah build its own tunnel network in the Middle East.

He says there is no indication of strengthened ties between North Korea and Hamas or Hizballah since the deadly assault on Israel, but that whenever a major military crisis occurs, "North Korean-made arms regularly pop up." This, he says, is in part because "North Korea seeks to exploit these conflicts for their own financial gains and actively tries to find purchasers of their weapons."

The North Korean delegation's visit to Tehran, coming just a month after a similar visit to Moscow, raised concerns that Pyongyang could be entering a broader partnership involving Iran and Russia. That prospect has gained attention with North Korea's reported provision of munitions to aid Russia's war effort in Ukraine.

As to why Iran might seek cooperation with Pyongyang instead of other allies such as Russia or China -- fellow members of the burgeoning bloc of the sanctioned -- Katzman said that "North Korea would be probably the most willing."

"There is that history of relationships on missiles, and North Korea certainly doesn't really care about being subjected to any more sanctions," Katzman said. "So, North Korea would not be hesitant to share that technology."
