The relationship between globalization and China has been reversed. In particular, the recent U.S. attack on tiktok and wechat applications in China has been publicly known as the “cold war” in the United States. There is growing concern that the world will be polarized and that Europe will have to decide which side to take. The current situation is very unfavorable for Europe, especially Germany. Few countries have benefited as much from global economic openness as Germany. German automobile and machinery manufacturers are like fish in the water in the Chinese market. In turn, Chinese made smartphones benefit the European market. The presence of apple and Huawei offers consumers a choice. “Old world” Europe couldn’t compete with America in social media, but the Chinese did. China has also become an international leader in some fields, such as 5g technology, electric vehicle batteries, voice recognition software, space exploration and other fields. On the other hand, the United States is particularly affected by China’s rapid economic growth. After China’s accession to the WTO, many American products have been replaced by “made in China”. Rising China is challenging America’s position as the only superpower. A recent example is tiktok’s challenge to America’s cultural power. The power struggle between China and the United States is almost carried out in accordance with the standard textbook of international relations. < / P > < p > polarization will bring a high cost to the world, and it will not be limited to economic losses. Europe must not succumb to the illusion that if trump is no longer president of the United States, the world will return to its former calm. Because the underlying causes of the tension between China and the United States will not disappear. The long-term strategy of the United States to China will not change, and China also has its own huge “circle of friends”. In view of this, Europe must strive to maintain contact with China and the United States. Europe is by no means worthless. In the field of digital technology, Europe really needs to catch up. But European industrial products are crucial to both China and the United States. Europe also has a huge market with strong attraction to both China and the United States. Therefore, there is no reason for Europe to be led by either side by the nose.
