The US has said it will impose visa restrictions on Chinese officials accused of involvement in repression of Muslim populations.
It follows the decision on Monday to blacklist 28 Chinese organisations linked by the US to allegations of abuse in the Xinjiang region.
US Secretary of State Mike Pompeo said the Chinese government had instituted "a highly repressive campaign".
China has dismissed the allegations as groundless.
In a statement, Mr Pompeo accused the Chinese government of a string of abuses against Uighurs, ethnic Kazakhs, Kyrgyz Muslims and other minority Muslim groups.
These included "mass detentions in internment camps; pervasive, high-tech surveillance; draconian controls on expressions of cultural and religious identities; and coercion of individuals to return from abroad to an often perilous fate in China". _Agencies
