The top U.S. official on energy policy says China should allow American companies to qualify for subsidies Beijing offers for renewable energy projects. There are growing complaints that China violates world trade rules by subsidizing its green energy companies, such as solar panel and wind turbine manufacturers. “What we in the U.S. ask for and we think China will come along with, is that these subsidies are equal on a level playing field. So those are the principals we are going to go forward on,” he said. Chu says the U.S. recognizes subsidies are the direction both countries must go in to achieve the goal of lowering carbon emissions and reducing pollution and global warming.
