In 2018, China imposed a 25 percent tariff on a wide range of U.S.- origin products including pork, beef and soybeans.  This action was in retaliation to tariffs placed on steel and aluminum imported from China. 

The complaint subsequently filed by the U.S. over the retaliatory tariffs was reviewed by the World Trade Organization. A panel concluded that the action by China was inconsistent with trade rules. In response China stated that it is "studying the conclusions of the WTO panel and will follow-up in accordance with rules".

Predictably China is requesting that the U.S. should rescind tariffs on steel and aluminum.
