On February 4, Joseph Nye, Professor of Harvard University, published an article entitled Biden’s Asian triangle. The full text is excerpted as follows: < / P > < p > how Joe Biden deals with relations with China will be one of the decisive issues in his presidency. The Sino US relations he took over are at the lowest point in 50 years. Some blame his predecessor, Donald Trump. Trump should be responsible for adding fuel to the fire. < / P > < p > at the same time, the United States and China are still interdependent economically and on ecological issues that go beyond bilateral relations. It is impossible for the United States to order its economy to completely decouple from China without paying a huge price. < / P > < p > during the cold war, the United States and the Soviet Union had little economic or other interdependence. In contrast, the annual trade volume between the United States and China is about $500 billion, and the two sides have extensive student and tourist exchanges. More importantly, China has learned to use market power in a way that the Soviet Union never mastered, and it is a trading partner of more countries than the United States. < / P > < p > given China’s population size and rapid economic growth, some pessimists believe that it is impossible to influence China’s behavior. But from the perspective of the alliance, this is not the case. The combined wealth of developed countries – the United States, Japan and Europe – far exceeds that of China. This strengthens the importance of the Japan US Alliance for economic stability and prosperity in East Asia and the world. At the end of the cold war, many people in both countries believed that this alliance was a legacy of history. < / P > < p > former President Clinton’s China policy provided contacts, but he also bet on both sides, reiterating that the security relationship with Japan is the key to deal with China’s geopolitical rise. At that time, there were three major powers in East Asia. If the United States continued to form an alliance with Japan, these two countries could shape the environment in which China’s strength grew. In addition, if China tries to drive the United States out of the first island chain as part of its military strategy to drive the United States out of the region, Japan, which is the most important part of the island chain, is still willing to provide generous host country support to the 50000 U.S. troops stationed there. As a thoughtful and skilful implementer of Clinton’s policies at the time, Kurt Campbell is now Biden’s key national security council coordinator in the Indo Pacific region. < p > < p > former Prime Minister Shinzo Abe’s leadership reinterprets Article 9 of Japan’s post-war constitution in order to strengthen Japan’s defense capability under the UN Charter. After trump withdrew from the trans Pacific Partnership Agreement, Abe retained the agreement in the form of a comprehensive and progressive trans Pacific Partnership Agreement. < / P > < p > under the leadership of the new prime minister, Kan Yiwei, who was Abe’s chief cabinet secretary and is likely to continue his policies, Japan’s regional leadership is likely to continue. < / P > < p > the Japan US alliance is still very popular in these two countries, and they need each other more than ever. If Japan and the United States are united, they can balance China’s strength and cooperate with China in areas such as climate change, biodiversity, epidemic prevention and committed to building a rule-based international economic order. For these reasons, as the Biden administration develops strategies to cope with China’s continued rise, alliances with Japan will remain a top priority.
