First of all, the disintegration of the Soviet Union and the drastic changes in Eastern Europe directly led to the weakening of the Eastern bloc in the world, and China became the largest socialist polar body in the world. In order to unite the strength of the Eastern Group, five socialist countries, China, Korea, Viet Nam, Cuba and Laos, helped each other to resist the erosion of capitalist countries.

In 1970s and 1980s, African countries became independent one after another, and began to establish their own diplomatic circles in 1990s. In 1970s, when China resumed its seat in the United Nations, they received strong support from African countries. President Mao Zedong once said, "It was our black African brothers who brought us into the United Nations." This famous saying, and in the seventies and eighties, African countries received a lot of material help from our country every year, which helped the construction of African countries. African blacks still resist or don't welcome American-led whites. On the contrary, they are close to us yellow people.

Third, China and the United States established diplomatic relations in the late 1970s and early 1980s. The United States-led NATO has been established for nearly 40 years. After years of running-in, we became more in step and established diplomatic relations with China under the influence of the United States.

Fourth, this is the most important point. As the saying goes, "a weak country has no diplomacy", 1992 China will vigorously develop its economy, which was the early stage of reform and opening up. With the establishment of Shenzhen, Shantou, Zhuhai and Xiamen Special Economic Zones, it is time for China to vigorously develop its economy. After the founding of People's Republic of China (PRC), China will face the blockade of the United States for nearly 30 years, and sometimes it is necessary to guard against the "hidden knife" and "retreat" of the big brother of the Soviet Union. Coupled with the obstruction of domestic conservatives, only domestic development can be carried out, and in short, the comprehensive national strength has increased, and people can listen to what they say.
