China detains Myanmar think tank founder U Min Zin on espionage suspicion

Chinese authorities have detained U Min Zin, the founder of a Myanmar-focused think tank, on suspicion of espionage and endangering China’s national security, opening another opaque case that could chill academic and policy work tied to the country. China’s foreign ministry said Min Zin was placed under criminal detention and notified the U.S. side, but disclosed no facts about the alleged conduct, the evidence, or where he is being held.

Min Zin leads the Institute for Strategy and Policy Myanmar, a research organization that has produced analysis on Myanmar’s politics, trade, rare-earth exports and China-Myanmar relations. He is also reported to be a U.S. citizen, a Ph.D. candidate at the University of California, Berkeley, and a former student activist in Myanmar’s 1988 democracy movement. His detention in Kunming, in Yunnan province, places the case squarely in a region that sits at the center of China’s economic and security interests along the Myanmar border.

The arrest comes as Beijing keeps close watch on issues that intersect with Myanmar’s fractured post-coup economy, especially trade flows and rare-earth exports. ISP-Myanmar has said the discrepancy in reported trade values between Myanmar and China exceeded $63 billion over the past eight fiscal years, with more than $45 billion emerging after Myanmar’s 2021 military coup. The group has also said Myanmar became China’s primary external source of rare earth minerals from 2017 to 2024, with export value exceeding $4 billion.

Those minerals matter because they feed supply chains far beyond Myanmar. A Stimson Center article citing ISP-Myanmar said active mining sites in Kachin State rose from about 130 in 2020 to more than 370 by the end of 2024, underscoring the speed and scale of extraction in an area that has become strategically important to Beijing. ISP-Myanmar has also maintained regular exchanges with Chinese think tanks and has published work on Chinese foreign policy, making the opacity of the espionage allegation especially consequential for researchers operating near politically sensitive topics.

The detention is likely to draw close attention in Washington, where any case involving a U.S. citizen held by China on national-security grounds carries immediate diplomatic weight. It also reinforces longstanding fears among foreign scholars, policy analysts and humanitarian workers that research on China-linked border and trade issues can carry legal risks that are difficult to see until they become personal.
