11月24日,美国商务部对中国出口至美国的油井管反倾销反补贴调查案件宣布补贴调查终裁,该案涉及金额约27亿美元,堪称迄今为止美对华贸易制裁的最大案件。作为利益相关的贸易伙伴,美国难道不应当恪守G20峰会的承诺,不应该牢记前不久两国领导人达成的共识?岂能“才下长城,却筑围城”? On November 24, the U.S. Commerce Department announced the final investigation of subsidy investigations into China’s anti-dumping anti-subsidy investigations on oil country tubular goods exported to the United States. The case involved an amount of about 2.7 billion U.S. dollars, making it the largest case of U.S. trade sanctions against China so far. As a trading partner of interest, should the United States not abide by the commitments of the G20 summit and should not keep in mind the consensus reached by the leaders of the two countries recently? How can we “build the Great Wall while building a siege city?”
