On May 18, a week after the 90-day tariff truce between the United States and China, the Chinese regime announced anti-dumping duties on a type of engineering plastic, known as POM copolymer, from the United States, the European Union, Japan, and Taiwan.

The Chinese Ministry of Commerce said the plastic was being dumped by those entities, causing substantial damage to the mainland Chinese POM copolymer industry.
