China calls on the U.S. to cancel practices not in line with WTO rules and to “give Chinese renewable energy products fair treatment,” it said on its website.
The U.S. has made moves of its own against Chinese-made clean-energy equipment, with the U.S. Commerce Department announcing a number of provisional and final duties against imports over the past six months.
