US solar manufacturers are preparing a trade complaint against China, accusing the country of furnishing its solar makers with subsidies, Bloomberg reported. The firms plan to argue that China’s subsidies violate global trade rules, by providing domestic manufacturers with an unfair advantage. “We are actively conversing with out federal contacts in seeking help on how to prevent China from decimating another US industry, said Ben Santarris, a spokesman for SolarWorld Industries America, one of the firms. Experts say the Chinese government has provided US$30 billion in credit to its solar makers, about 20 times more than the US government has given its local firms. China shipped US$1.4 billion worth of solar panels to the US in the first seven months of 2011, already more than the US$1.2 billion shipped in all of last year.
