奧巴馬宣佈就中國對美國生產的汽車徵收關稅一事向世貿組織提出了申訴

U.S. President Barack Obama says his government will fight to hold China accountable for practices harming American automakers.

Speaking at a campaign stop near Toledo, Ohio Thursday, Mr. Obama said Americans need a "fair playing field." He announced a new complaint with the World Trade Organization on more than $3 billion in allegedly unfair Chinese duties on American-made cars.

Toledo is home to a big auto plant complex. Mr. Obama told the crowd that six previous WTO challenges to China have been successful.

Mr. Obama is spending Thursday and Friday in Ohio and Pennsylvania, two crucial states in the November general election.

He carried both in the 2008 election, and recent opinion polls show him holding a narrow lead over his Republican opponent, Mitt Romney. The president will use the campaign swing to portray himself as a champion of average, working-class Americans, and to portray Romney as a wealthy businessman before he entered politics.美國總統奧巴馬錶示，美國政府將會繼續努力，讓中國爲其損害美國汽車製造商的行爲承擔責任。

奧巴馬在俄亥俄州的托萊多小鎮附近做競選演講時表示，美國人民需要“一個公平競爭的環境”。星期四，奧巴馬宣佈就中國對美國生產的汽車徵收30多億美元新關稅一事向世貿組織提出了申訴。

托萊多是一個大型汽車製造廠的所在地。奧巴馬對聽他演講的民衆說，以往美國曾經六次向世貿組織提出針對中國的申訴，都獲得了成功。

奧巴馬將於星期四和星期五在俄亥俄州和賓夕法尼亞州進行競選活動，這兩個州對11月的總統大選十分關鍵。

2008年大選中，奧巴馬在這兩個州都贏得了勝利，最近的民意測驗顯示，他在這兩個州以微弱優勢領先於他的共和黨競爭對手羅姆尼。奧巴馬意欲藉助這次競選巡訪凸顯他是普通民衆和工薪階層更理想的代言人並將自己與從政前就已是富商的羅姆尼進行對比。
