SolarWorld Industries America led six other companies in forming the Coalition for American Solar Manufacturing October 19, and at the same time filed petitions with the Commerce Department and the U.S. International Trade Commission claiming that China is illegally dumping solar energy products into the U.S. market and receiving massive subsidies from their government that violate World Trade Organization rules and put all other companies around the world at a competitive disadvantage. The petitions, backed by Oregon Senators Ron Wyden (D) and Jeff Merkley (D), ask the Commerce Department to begin its investigation within the next month and have the International Trade Commission file a preliminary determination by the end of the year, and a final determination in about a year. The next day, the Chinese Commerce Ministry rebuked the move, saying that the complaint may harm global economy recovery.
