China's Ministry of Commerce announced on Thursday that it has initiated an anti-dumping investigation into imports of carya illinoensis originating from Mexico and the United States.

The investigation became effective on Thursday, the ministry said in a statement.

Evidence has shown that Mexico and the United States have engaged in the dumping of carya illinoensis exports to China, causing substantial harm to China's domestic industry, a spokesperson for the ministry said in response to a media query.
