China, which Trump subjected to a tariff of 10 per cent on goods exports, had vowed to challenge the step at the WTO. In a statement cited by the WTO, China's government said the measures appeared to be inconsistent with US obligations under the agreement that led to the creation of the trade body.

The World Trade Organization said China submitted a request for consultations with the U.S. on the tariffs. China said the duties are discriminatory.
