"The US decision is a blunt intervention in China's internal affairs and a serious breach of key norms of international relations. We reject and condemn this", the diplomat said.
According to the representative, "China has decided to take countermeasures regarding US citizens and organisations for unbecoming behaviour on issues related to Xinjiang".
The statement comes as a response to recent US sanctions on the Xinjiang Public Security Bureau (XPSB) and four current or former Chinese officials, imposed on Thursday under the Uyghur Human Rights Policy Act that allows Washington to apply sanctions against Beijing over alleged human rights violations.
According to the US, China has been holding up to one million ethnic Uyghurs and other Muslims in re-education camps in the autonomous region, abusing their rights. China has repeatedly refuted the accusation, stating that the only reason for detentions in the area is linked to "fighting violence, terrorism, and separatism". Beijing also stressed that the facilities called "re-education camps" by the US are actually education centres, where Uyghurs can learn the official language.
