Chinese security officials detained U.S. citizen U Min Zin, a political scientist who focuses on Myanmar, on accusations of endangering national security, according to sources familiar with the case.
Min Zin disappeared on June 3 while in Kunming, Yunnan Province, which shares a border with Myanmar. U.S. diplomats have been informed of the arrest. The sources spoke anonymously because of the sensitive diplomatic context surrounding the previously unreported detention.
Arrests of American nationals on national‑security charges are rare in China, and the move comes as President Trump and Chinese President Xi Jinping seek to deepen bilateral cooperation.
Min Zin is the executive director of a policy‑research institute originally based in Yangon. Following the 2021 military coup, the group has operated from various locations. He has lived and worked in the United States, Myanmar and currently resides in Thailand.
His commentary on Myanmar politics has appeared in The New York Times, Foreign Policy and other major outlets.
“We are aware of reports regarding a U.S. citizen detained in China,” the State Department said in a statement, adding that it provides consular assistance to detained Americans. No further details were offered, citing privacy regulations.
Min Zin’s wife did not respond to a request for comment, and the Chinese embassy in Washington offered no immediate comment.
The detention occurred less than three weeks after President Trump attended a summit and state banquet in Beijing hosted by President Xi, during which Trump praised Xi and advocated for a “G2” partnership focused on cooperation.
Trump has long expressed admiration for Xi and has accommodated China following the trade tensions that began under his administration.
The use of a national‑security charge against another American complicates the diplomatic rapprochement. One U.S. official noted that, despite Chinese assurances of “constructive strategic stability,” the arrest undermines those efforts.
John Kamm, founder of the Dui Hua Foundation, estimates that about 200 Americans are detained in China for various reasons, including drug offenses and “exit bans” tied to commercial or financial disputes.
Kamm is unaware of any current U.S. detainee charged with endangering national security. He cited previous cases such as Kai Li, released in a 2024 prisoner swap, and Sandy Phan‑Gillis, expelled in 2017 after a two‑year detention.
He also mentioned a recent detention of an American on alleged economic crimes, though details remain sparse.
The reasons for Min Zin’s arrest in Yunnan are unclear. While Yunnan once hosted a sizable Myanmar community, that presence has declined since the pandemic. China has at times supplied aid to armed groups operating across the border, but it is unknown whether Min Zin’s research intersected with those activities.
The Chinese Communist Party maintains close ties with Myanmar’s military‑linked government, a subject on which Min Zin has written extensively.
A Nepali research organization announced in May that Min Zin was slated to speak at a policy forum in Nepal later this month. His biography notes that the Institute for Strategy and Policy Myanmar, founded in Yangon, “promotes democratic leadership and civic participation.”
The biography also lists him as a Ph.D. candidate in political science at the University of California, Berkeley, with research interests in civil‑military relations, democratization and ethnic conflict. His LinkedIn profile indicates he earned a master’s degree in political science from Berkeley between 2010 and 2016.
His opinion pieces for The New York Times have focused on those topics, especially after the Tatmadaw’s 2021 coup.
In a June 2021 essay, he described a “stalemate” between the military and opposition, warning that the Tatmadaw intended to force an election through brutal crackdowns, the dissolution of the National League for Democracy, and the potential life‑sentence of former de‑facto leader Aung San Suu Kyi.
He also observed a shift in the anti‑coup movement toward more violent resistance.
His predictions have materialized as Myanmar descends into civil war, with the military employing Chinese and Russian‑made weapons in airstrikes against civilian areas.
U.S. officials have long advocated for the release of Americans detained in China and for the liberation of high‑profile foreign prisoners, including Hong Kong media tycoon Jimmy Lai, Chinese pastor Jin Mingri (Ezra), and journalist Dong Yuyu.
President Trump has indicated plans to host President Xi in Washington around September 24 for a reciprocal visit.
Kamm expressed doubt that upcoming summits will result in prisoner releases, stating, “Human rights is not a priority for the U.S. government in its dealings with China. I hope I’m wrong, but I see no evidence to the contrary.”
