China’s commerce ministry announced this week that it will extend anti-dumping measures on imports of U.S. broiler chicken products for a further five years, effective from September 27. A suspension of the measures would potentially hurt Chinese firms, according to a statement posted on the ministry’s website on Monday.

China first imposed the duties on chicken imports from the United States in September 2010, claiming that chicken was subsided in the United States and then dumped on the Chinese market at prices below fair market value.

China’s commerce ministry said on August 22 that China would extend anti-subsidy measures on imports of U.S. broiler chicken products for a further five years, effective from August 30.

In May 2016, U.S. Trade Representative Michael Froman mounted a challenge to China at the World Trade Organization because of the Chinese Government’s failure to bring its anti-dumping and countervailing duties against imports of U.S. chicken into compliance with WTO rules. In 2013, a WTO dispute settlement panel found that China’s anti-dumping and countervailing duties violated its WTO obligations.  Despite that decision, China continues to refuse to remove these duties.

Chicken is the fastest-growing protein in overall consumption terms in China and accounts for nearly a fifth of total meat consumption.
