____________________________.As the U.S. complains about Chinese auto parts and China complains about the new U.S. tariff law. China today went to the World Trade Organization accusing the United States of unfairly raising tariffs on 30 products including tires and kitchen appliances. China's action came as the U.S. Trade Representative filed a complaint over allegedly improper government subsidies for China's auto industry. U.S. President Barack Obama is expected to discuss the complaint during a campaign stop in the mid-western state of Ohio.美国对中国的汽车零部件颇有怨言,而中国则对美国的新税法抱有不满.今天中国向世贸组织提起诉讼,指责美国不正当地提高了包括轮胎和厨房用品在内的三十样产品的关税.中国此举源于美国贸易代表的指控,据说中国政府不正当的补贴本国汽车工业.美国总统贝拉克奥巴马预计将于大选途中在中西部的俄亥俄州讨论这一争端.
