On March 22, the Trump administration of the United States took office for two months, and diplomatic characteristics began to appear. In order to realize the promise of "American priority" during the election campaign, the Trump administration has shown unprecedented determination in trade and immigration; When dealing with old allies Europe and Japan, the Trump administration has "both soft and hard", and small frictions continue while cooperating. The Trump administration, which shouted the slogan "America first" in the election campaign, first adopted a tough line on foreign trade policies that made supporters feel the results most easily. 65438+1October 20th, after the Trump administration took office, it announced its withdrawal from the Trans-Pacific Partnership Agreement (TPP) according to its campaign promise. In addition, the North American Free Trade Agreement (NAFTA) signed with Mexico and Canada will also be renegotiated. For the World Trade Organization (WTO), which supports the United States in promoting free trade, the Trump administration indicated that it may not abide by its dispute settlement procedures. On March 18, the G20 Finance Ministers and Central Bank Governors Meeting attended by Japan, the United States, Europe and emerging market countries closed in Germany. Until the end, the United States still adhered to the trade policy, calling for the deletion of "anti-protectionism" as the basic expression of G20 knowledge in the joint statement and the addition of "free and fair trade" implying trade imbalance. According to the United States, the expression "opposing protectionism" disappeared from the joint statement. In terms of immigration, the Trump administration has also fulfilled its campaign promise. High walls and other security facilities have been built intermittently on the 3,200-kilometer-long US-Mexico border, but the Trump administration still hopes to turn the entire border into a "Great Wall" of reinforced concrete by building new walls to stop illegal immigrants and drug dealers. On March 19, local time, the US Department of Homeland Security announced the bidding plan for wall repair. The new wall is not only unattainable, but also goes deep underground, becoming the "Great Wall" to prevent Latin American "stowaways" from crossing. However, people are particularly concerned about who will pay the huge cost of building a wall. Trump has repeatedly stressed that the cost of building the border wall is borne by Mexico. Although Trump still insists on this statement, he may not directly ask the Mexican government to pay the bill because the Mexican side has rejected this possibility. On the other hand, after two consecutive editions of the "Mu Ban Order" were blocked, the Trump administration vowed to appeal the court's ban and was determined to raise the threshold for immigrants to enter the United States. For ally Japan, as early as Trump took office, US Secretary of Defense Matisse re-examined the security commitment to Japan on behalf of the United States. Recently, US Secretary of State Tilson visited Japan and reaffirmed the strengthening of the alliance, which made Abe express with satisfaction after his talks with Tilson that he felt that "the Japan-US alliance has entered a new stage". But the relationship between Japan and the United States in the economic field is obviously not as harmonious as that in the political field. Takubo Zhongwei, emeritus professor of Xinglin University in Japan, published an article entitled "It is too early to be optimistic about Japan-US relations" in the Japanese media. The article said that after Trump took office, with Abe's successful visit to the United States and the understanding of security agreements and economic cooperation between the two countries, Japan-US diplomatic relations have achieved rare results. However, Trump advocates "American priority", which makes people suspect that he is likely to pursue "protectionism". Will Japan and the United States face the same threat? Japan needs caution. As Takubo's Nakao was worried, Wright Heze, nominee of the Office of the United States Trade Representative (USTR), made it clear that "Japan will be the first target" in the trade negotiations between Japan and the United States in the agricultural field. Navarro, chairman of the National Trade Commission (NTC), which formulates trade policies, said with fists clenched, "It will reduce Japan's thorny non-tariff barriers." Japan's Yonhap News Agency said that the "hawks" in the trade field have increased their influence in the Trump administration and launched an offensive against Japan to increase exports. Japanese business people said that "there will be difficult negotiations sooner or later." It is in stark contrast to 19 seconds of smiling and shaking hands with Abe in February. On March 17, when German Chancellor Angela Merkel visited the White House, Trump was expressionless and did not respond. Not only that, he also criticized Germany for owing NATO a lot of money. "The United States has provided Germany with strong and very expensive defense assistance, and Germany must pay more." Although the White House came forward to clarify that Trump "didn't see it at that time", it didn't mean that he didn't shake hands, but some public opinion thought that this somewhat reflected Trump's attitude towards Europe-Trump has been slamming Europe's refugee policy and criticizing NATO, which forced many EU leaders to respond: European affairs "don't need advice from outsiders". In this regard, European Commission President Juncker believes that the interaction between the United States and Europe has "entered a stage of estrangement" and the relationship between the EU and the United States has fallen to a historical low. He also warned that there is a potential risk of a trade war between the United States and the European Union, and Europe "must take seriously the protectionist remarks of the Trump administration and be prepared". As the German media commented on this handshake, Merkel, as the last spokesperson of the western free world, became the opposite of Trump who advocated "American priority". The collision between the Trump administration and Europe is a collision between "American priority" and "political correctness" in Europe, and it broke up in discord.
