China’s Commerce Ministry said Thursday that it will investigate the fashion company PVH, which owns brands like Tommy Hilfiger and Calvin Klein, for suspected violations of trade rules.

The ministry said Thursday in statements posted online that it would investigate the company’s suspected boycott of products from the far western Xinjiang region, where China’s ruling Communist Party is accused of holding members of mostly Muslim ethnic groups in detention camps.

Washington has blocked some imports from Xinjiang, while Beijing has protested against such moves. China denies any abuses and says steps it has taken are necessary to combat terrorism and a separatist movement.

Companies that buy clothing, cotton, tomatoes and other goods from Xinjiang face pressure from western consumers over alleged human rights violations in the region, while Beijing has whipped up Chinese anger at brands that express concern about possible forced labor.
