Developing countries are a group of countries that had emerged in the wake of World War n. During the Cold War, countries were first divided into two camps: the imperialist one and the socialist one. In 1974, the late Chairman Mao Zedong put forward his theory of three worlds, in which he classified the world into three: the Soviet Union and the United States were the First World, the Asian, African and Latin American countries were the Third World, and those in between were the Second World. Chairman Mao's classification accentuated the thinking of anti-hegemony, making it more targeted politically. In the 1980s and 1990s, they were conveniently called developing countries, which focused on more economic and social development. Developing countries have always been an important force that allow of no neglect in international politics though the end of the Cold War has witnessed different views on their status and role in the pattern of international relations. This paper attempts to explore problems facing the developing countries today and their status and role in international politics, and China's relations with them.
