China Loses WTO Appeal in U.S. Speciality Steel Case

China comprehensively lost an appeal on Thursday against a World Trade Organization ruling in a dispute over U.S. exports of speciality steel used in power transformers.

The dispute involved duties imposed by China on "grain-oriented electrical steel'', a product made by AK Steel Corp and ATI Allegheny Ludlum, which are based in the electoral battleground states of Ohio and Pennsylvania.
