An appeals court judge at the World Trade Organization (WTO) says the United States did not fully comply with its ruling and could face Chinese sanctions if it does not remove certain tariffs that break WTO rules.

According to the trade regulator, 11 US countervailing measures have violated WTO rules. It has asked Washington to rectify the irregularities.

The decision relates to a case that dates back to 2007. It follows China’s appeal to the WTO in 2012 to challenge US anti-subsidy tariffs on Chinese exports. These exports included solar panels, wind towers, steel cylinders and aluminum extrusions, with an estimated value of $7.3 billion at the time. (RT)
