GENEVA, SWITZERLAND — The World Trade Organization (WTO) will investigate a dispute between China and the United States over Beijing’s use of rice, wheat and corn import controls, Reuters reported.

In 2019, WTO ruled against China’s use of tariff-rate quotas for agricultural imports, which the US said had limited market access for its exports. The quotas allow a specific quantity of goods to be imported at lower-than-normal rates.

China said it has implemented WTO recommendations, but the United States disagrees and believes it is due countermeasures against Beijing.

The WTO usually presents its ruling to the parties involved within six months, after a series of hearings and consultations.
