A US scholar, Min Zin, stops responding after traveling to China for a workshop. On June 5, the US Consulate General in Guangzhou confirms to his family that he has been detained in China’s Yunnan province.

Chinese authorities accuse him of endangering national security. The reporting focuses on the confirmation from the US side and the stated Chinese allegation, while providing limited additional details about the underlying claims or the circumstances of the detention.

Across the available coverage, the key points are consistent: Min Zin is detained in Yunnan; the US consulate informs the family; and Chinese authorities cite national security concerns. No further details on charges, legal process, or dates of detention are included in the cited accounts.
