China's photovoltaic (PV) industry issued a statement on Wednesday, opposing the United States' second anti-dumping investigation on Chinese PV products. Representatives from the China Chamber of Commerce for Import and Export of Machinery and Electronic Products, China Renewable Energy Industry Association, China PV Industry Alliance and major manufacturers including Yingli Solar, Trina Solar pushed down a symbolic "wall of trade barriers" at a press conference in Shanghai on Wednesday. The joint statement called for the U.S and China to solve the disputes through negotiations. Chinese PV products are well received in the world for their low cost and efficiency, high quality and comprehensive after-sales services, without dumping and illegal subsidies at all, according to the statement. Trade protectionism seriously hinders the industry development and will affect the development of U.S. real economy and employment, it said. On Feb. 14 this year, the U.S. International Trade Commission (USITC) determined an affirmative indication regarding injury to the U.S. industry as part of the new anti-dumping (AD) and counterveiling duty (CVD) petitions against PV products from the Chinese mainland and Taiwan. It was the second U.S. investigation against Chinese PV products after a similar one in 2011, which seriously affected the Chinese PV industry and hindered the development of U.S. PV application market. The Chinese PV industry has been recovering since the second half of 2013 but encountered the unexpected second U.S. investigation in February. The U.S. Department of Commerce is expected to release the preliminary CVD investigation result on June 2 and the preliminary AD investigation result on July 28 and release final results on Dec. 11. The USITC will determine whether to levy taxes on Jan. 26, 2015.
