In the face of the threat of Trump's tariff landing on March 4, Mexico has proposed to levy tariffs on China equivalent to those imposed by the United States on China, and hyped it as "very interesting". At the same time, he called on Canada to follow the relevant measures, and the new Finance Minister Besant responded positively. This may be the most important purpose of Trump at the beginning of wielding the tariff stick to its allies: to let allies with strange dreams stand behind one another under high pressure, and jointly attack Dongda from the economic, trade, economic, technological and other levels instead of the previous careful thinking. The essence of Trump's push for a truce between Russia and Ukraine is to quickly withdraw from Russia, Ukraine and Eastern Europe and draw on already strained strategic resources, either to the Middle East or to the Asia Pacific.
