Tesla’s announcement that it has opened a showroom in Xinjiang has attracted criticism from US rights and trade groups, making it the latest foreign firm caught up in tensions related to the far-western Chinese region.

Xinjiang has become a significant point of conflict between Western governments and China in recent years, as UN experts and rights groups estimate more than a million people, mainly Uyghurs and members of other Muslim minorities, have been detained in camps there.

China has rejected accusations of forced labour or any other abuses there, saying that the camps provide vocational training and that companies should respect its policies there. The US electric car maker announced the showroom’s opening in Xinjiang’s regional capital, Urumqi, on its official Weibo account last Friday. “On the last day of 2021 we meet in Xinjiang,” it said in the post.

On Tuesday, the Council on American-Islamic Relations, the largest US Muslim advocacy organisation, criticised the move, saying that Tesla was “supporting genocide”.

The US has labelled China’s treatment of ethnic Uyghurs and other Muslims in Xinjiang as genocide. The US and a few other countries plan a diplomatic boycott of the Beijing Winter Olympics in February over the issue.
