PARIS (AP) — French prosecutors have opened an investigation into alleged involvement in crimes against humanity based on claims that global retailers rely on forced labor in China. Human rights groups filed a legal complaint that includes accusations against retailers including Uniqlo and the makers of Skechers shoes and Zara clothes. The rights groups say the companies are benefiting from a Chinese system of repression against Uyghur and other Muslim minorities in the Xinjiang region. The Chinese government on Friday reiterated denials of any forced labor in Xinjiang, and lashed out at what it called interference in its internal affairs.
