China has no choice but to take necessary countermeasures in response,” the ministry said in a statement. It also warned of further sanctions if the U.S. rolls out new restrictive measures against China. Six U.S. entities, including Applied DNA Sciences, Inc. and the non-governmental group Human Rights in China, were banned from engaging in trade or other activities with entities in China. The State Administration for Market Regulation announced that companies in the U.S. that conduct follow-up factory inspections on behalf of Chinese entities for CCC certification can no longer provide these certifications. In December, the U.S. FCC banned the import of new Chinese drones, though it later revised that ban to allow for some models.
