美中貿易糾紛升級

Trade disputes between the United States and China are heating up, as Washington complains about Chinese auto parts and Beijing files a complaint about a new U.S. tariff law.

Monday, China went to the World Trade Organization accusing the United States of unfairly raising tariffs on 30 products including tires and kitchen appliances.

Beijing's action comes just hours after news reports said U.S. President Barack Obama would file a trade complaint over allegedly improper government subsidies for China's auto industry.

Administration officials say Mr. Obama will announce the move during a campaign speech in the state of Ohio.

Ohio is home to many autoworkers, and is seen as a vital political battleground in the race between Mr. Obama and his Republican rival Mitt Romney for the presidency.

The Democrats and Republicans have been accusing each other of failing to protect U.S. jobs in dealings with China.就在華盛頓當局即將向世貿組織投訴中國政府爲本國汽車零件工業提供補貼，中國就美國新的關稅法向世貿組織投訴之際，美中貿易糾紛升級。

中國星期一向世貿組織控訴美國對輪胎和廚房電器等30種產品提高關稅。

在中國採取這項行動的幾個小時之前，有報道說，美國總統奧巴馬要控訴中國政府爲中國汽車工業提供不當補貼。

美國政府官員說，奧巴馬將在俄亥俄州的競選演說中宣佈這項措施。

俄亥俄州有許多汽車製造廠，也是奧巴馬和共和黨總統候選人羅姆尼爭奪選票的關鍵政治戰場。

民主黨和共和黨互相指責對方在和中國打交道時沒有保護美國的就業機會。
