China to investigate U.S., South Korean solar imports BEIJING (Reuters) - China will start anti-dumping and anti-subsidy investigations into U.S.-produced solar products, the country's trade ministry said on Friday, in the latest sign of growing tensions between major solar product manufacturers. The Ministry of Commerce said in a statement on its website it would also begin anti-dumping investigations into solar products from South Korea. Chinese solar manufacturers have criticized U.S. tariffs set this year as a threat to their young industry that would slow its growth by raising costs. Reporting By Xiaoyi Shao; Editing by Paul Tait
