Weak countries have no diplomacy. In the late Qing Dynasty, Li Hongzhang and Li Tang Zhong played the role of "riffraff" and saved many interests for China. The Republic of China mainly followed the western powers such as Britain and the United States and won the support of Britain and the United States to defeat the Japanese. After the new China, it mainly stood on the side of the big brother of the Soviet Union. After China and the Soviet Union became enemies, it made friends and attacked Latin America against the Soviet Union. After the disintegration of the Soviet Union, it seems that it became the boss of developing countries and began to be independent and peaceful. In fact, this is to avoid confrontation with the United States.
