The US has promised to sanction the Chinese officials who allegedly abuse Muslim minorities in Xinjiang.
Authorities in Xinjiang is blamed to have retained millions of people in re-education camps in recent years. Mr Chen is among the highest-ranked Chinese official who has been affected by the US sanctions.
Mr Chen was seen to be the one behind Beijing’s strategies on minorities and was also previously in charge of Tibet.
The other officials who were targetted are Wang Mingshan, director of the Xinjiang Public Security Bureau, Zhu Hailun, a senior party member in Xinjiang and former security official in Huo Liujun.
All of them have been restricted from conducting any financial transactions in the US and if they do, they will have their US-based assets frozen.
According to the US Secretary of State Mike Pompeo, the state was acting against horrific and systematic abuses in the region, adding that the US will not tolerate this as the Chinese Communist Party carries out human rights abuses targeting a specific ethnic Kazakhs among other members of a minority group in the country.
Tensions between China and US erupted when coronavirus was reported in China since both blamed the other to be responsible for the deadly crisis.
China’s decision to introduce a national security law in Hong Kong is another thing that has stirred and worsened the situation.
