Foreign officials who enable the forced return of Uyghurs and other ethnic or religious groups to China face visa restrictions in the United States, Sec. of State Marco Rubio announced Friday.

The U.S. State Department has imposed visa sanctions on an unspecified number of current and former Thai officials for their role in last month’s deportation of 40 Uyghur asylum seekers to China.

A delegation from the Thai government will visit China this week to check on the welfare of dozens of Uyghur refugees, after their controversial deportation drew global condemnation and US travel sanctions on local officials.
