Xie Feng, the Chinese ambassador to the United States, appealed at the annual meeting of the Chicago Branch of the General Chamber of Commerce of the United States of China on the 3rd to continue to play the role of "ballast" and "stabilizer" in Sino US economic and trade cooperation, so as to inject new impetus into Sino US relations and open up a new world. Xie Feng said in his speech that some people are clamoring for the cancellation of China's permanent normal trade relations status, which will be a violation of international economic and trade rules and shake the foundation of the global trading system. Xie Feng pointed out that the weaponization of tariffs can easily trigger a vicious cycle of tit for tat, which not only fails to reduce the overall trade deficit, but also raises production costs, increases daily expenses, exacerbates inflationary pressures, and widens the wealth gap. 98% of economists believe that high tariffs will be borne by American consumers, and international institutions such as Moody's have warned that a tariff war will harm the US economy. Xie Feng quoted his American friend as saying that decoupling from China is like "shooting oneself in the foot", and the trade war has become the "Damocles sword" hanging over American companies. Xie Feng stated that in the new era, the common interests between China and the United States have not decreased, but have increased. Whether in the fields of economy and trade, agriculture, drug control, law enforcement, public health, or facing global challenges such as climate change and artificial intelligence, as well as international hot topics, cooperation between China and the United States is necessary. Win win cooperation is the best choice for China and the United States. Xie Feng pointed out that history has fully proved that cooperation between China and the United States benefits both sides, while confrontation harms both. The "new Cold War" cannot be fought and won, and the unwise containment of China will not succeed. (New Society)
