China Detains Two Japanese Nationals for Suspected Rare-Earth Smuggling

One detainee is reportedly an employee of a Japanese electric machinery maker's China subsidiary.
Chinese customs officials reportedly viewed the case as a concern but not espionage, with the detainees suspected of smuggling items prohibited for import or export.
Chinese authorities notified the Japanese Consulate-General in Shenyang and the Japanese Consular Office in Dalian about the detentions.
Some outlets framed the case within the broader context of rare-earths smuggling, as indicated by the SCMP report’s framing.
China has detained two Japanese nationals in Dalian on suspicion of smuggling rare-earth-related goods, Tokyo confirmed on June 24. Chief Cabinet Secretary Minoru Kihara told reporters both detainees are in good health and that the government is "taking appropriate steps to protect Japanese nationals," according to TRT World.
The first detention happened on May 18, the second on May 25. One detainee is reportedly an employee of a major Japanese electric machinery maker's China subsidiary, Kyodo News reported. Chinese authorities framed the arrests as routine law enforcement, not espionage — but the timing has rattled Japanese firms across Dalian and Shenyang.
The arrests did not happen in a vacuum. On January 6, 2026, China's Ministry of Commerce banned the export of "dual-use" items — including rare earths and magnets — to Japanese military users or companies that could boost Japan's defense capabilities, according to Free Malaysia Today. In February, Beijing went further, blacklisting 20 specific Japanese companies.
China controls roughly 70% of global rare-earth supply and 80–90% of refining capacity, according to South China Morning Post. That dominance gives Beijing enormous leverage. Analysts say the January ban made the legal definition of "smuggling" much broader — and far harder for Japanese firms to navigate.
Chinese Foreign Ministry spokesperson Guo Jiakun confirmed the detentions on June 24. He said they were carried out "in accordance with Chinese law" and called on Japan to "educate and remind its citizens and businesses in China to abide by Chinese laws and regulations," according to Global Times.
Tokyo struck a careful tone. Kihara said consular officials at the Japanese Consulate-General in Shenyang and the Consular Office in Dalian had been notified. He declined to share personal details about the detainees, citing privacy rules. Opposition lawmakers in Tokyo are already asking whether Japan's tougher defense policy is putting business people at risk, according to The Australian.
This is not the first time Japan and China have clashed over detained nationals. Since 2014, at least 17 Japanese citizens have been held in China. The most recent high-profile case ended in July 2025, when an Astellas Pharma employee was sentenced to three years and six months in prison for espionage — a verdict Tokyo still protests, according to Free Malaysia Today.
The 2026 case echoes a pattern from 2010, when a fishing boat collision near the Senkaku Islands triggered an unofficial Chinese embargo on rare earths to Japan. This time, though, the crackdown is backed by formal export control laws passed in 2023 — making each detention harder to challenge in court, according to South China Morning Post.
Dalian is a major hub for Japanese electronics and machinery. If "smuggling" charges are applied broadly to processed rare-earth products, Japan's supply chains for high-performance magnets and EV motors could face shortages fast. Japanese firms in the region are reportedly alarmed by the vague legal lines now separating legal trade from criminal smuggling, according to TRT World.
Japan is pushing G7 nations to set a price floor of $110 per kilogram for rare earths to reduce dependence on Chinese supply. These detentions could accelerate that push. If the detainees face long sentences, calls for full economic "de-coupling" from China are expected to dominate Japan's next Diet session, according to South China Morning Post.
