The allegation of "forced labor" in Northwest China's Xinjiang Uygur Autonomous Region is a huge lie, the Chinese Foreign Ministry said on Tuesday, urging the U.S. to immediately stop smearing China, stop intervening in China's internal affairs, and stop politicizing and weaponizing trade issues.

Chinese Foreign Ministry spokesperson Mao Ning made the remarks at a regular press briefing in Beijing, responding to media reports saying that the U.S. Department of Homeland Security is intensifying scrutiny of supply chains of American solar companies as the Biden administration mulls to tighten a ban on products assembled in Xinjiang.

The Chinese side has repeatedly pointed out that the allegation of "forced labor" in Xinjiang is a huge lie. The U.S. uses the so-called "forced labor" issue, which does not exist in Xinjiang, which often results in "forced unemployment" in Xinjiang, Mao said.

U.S.' move has severely undermined the basic human rights of the people of all ethnic groups in Xinjiang, violated international trade rules and disrupted international industrial and supply chains, the spokesperson said.

Mao said the U.S. must immediately stop smearing China, stop intervening in China's internal affairs under the pretext of human rights, and stop politicizing and weaponizing trade issues.
