当地时间1月20日，特朗普宣誓就任美国第47任总统，目前，其就任已有半个月，已对外宣布加征关税政策。自首次执政时起，对外加征关税，就是特朗普最为重视也最乐于使用的贸易政策手段之一。特朗普政府对外加税，会对国际经济与贸易秩序产生何种影响？

　　英国伦敦市经济与商业政策署前署长、中国人民大学重阳金融研究院高级研究员罗思义(John Ross)做客“东西问·中外对话”时指出，美国对他国实施加征关税政策，背后反映出美国国际竞争力下降的现实。作为超级大国，美国需要通过贸易保护措施，维护本国利益。

　　At noon on Jan. 20 local time, Donald Trump was sworn in as the 47th president of the United States in the Rotunda of the U.S. Capitol, beginning his second term. Starting his first tenure, tariffs have always been the trade policy tool that Trump prefers to use. What impacts will Trump’s tariff policies have on the global economic and trade order?

　　In the latest W.E. Talk, John Ross, former director of Department of Economic and Business Policy of the Mayor London and senior fellow at Chongyang Institute for Financial Studies at Renmin University of China (RDCY), told China News Network that the U.S. policy of imposing additional tariffs on other countries reflects the less effectiveness of the America's international competitiveness. Therefore, with an aim to keep its role as a superpower, the U.S. needs to safeguard its own national interests through trade protectionism measures.

　　He further pointed out that the majority of the global countries pursue the path of globalization, and if the Trump administration puts up the tariffs further, the American households will cost more and the inflation situation will get worse in the country. (Xue Lingqiao, Wu Xinru and Chen Caixia)
