China’s Commerce Ministry on Wednesday criticized the United States’ decision to impose broader anti-dumping and anti-subsidy tariffs on solar panels from China, The New York Times reported. The penalties are the latest round in a series of trade battles over the past four years involving China’s dominance in solar panel manufacturing. WTO rules prohibit subsidized exports and dumping, which is exporting goods for less than the cost to make and ship them, and allow countries to retaliate in the way the U.S has announced. China denies it has subsidized solar panel exports, despite evidence for such subsidies found in public filings and interviews.
