GENEVA: The United States did not fully comply with a World Trade Organization ruling and could face Chinese sanctions if it does not remove certain tariffs that break WTO rules, the WTO's appeals judges said in a ruling on Tuesday.

China went to the WTO in 2012 to challenge US anti-subsidy tariffs on Chinese exports including solar panels, wind towers, steel cylinders and aluminium extrusions, exports that it valued at $7.3 billion at the time.
