China has arrested an American citizen for alleged espionage, the country's government confirmed Friday, identifying the man as a political analyst for a policy think tank focused on neighboring Myanmar.
U Min Zin, a founder of the Institute for Strategy and Policy Myanmar, or ISP-M, has faced "criminal compulsory measures," Chinese Foreign Ministry spokesman Lin Jian said during a briefing on Friday.
Authorities are holding him on suspicion "of engaging in espionage and endangering China's national security," Lin said, without providing further details.
The ISP-M says it researches political, resource and conflict dynamics in Myanmar, which was plunged into civil war by a 2021 military coup.
U Min Zin was arrested on June 3 at Kunming Airport in the Yunnan province of China. ISP-M is based in the Northern Thai city of Chang Mai.
