US security threats against China and Russia and the formation of a security alignment (strategic partnership) between the two countries

The end of the Cold War was a turning point in international politics. The collapse of the Soviet Union shattered the bipolar structure of the international system and paved the way for the United States to remain the only superpower left in the world. Meanwhile, the relationship between the People's Republic of China as the world's second largest economic power and the Russian Federation the heir to the Eastern superpower is of particular importance. China and Russia have gone through ups and downs in their history. For example, the Soviet Union's support for the communist government of the People's Republic of China in the 1950s, the darkening of relations in the late 1960s and 1960s, and the coldness of relations in the two decades that followed. Although Gorbachev took steps to get closer to China in 1989, it was the collapse of the Soviet Union and the end of the Cold War that marked a turning point in the two countries' interactions and cooperation. After the early Westernization of Russian foreign policy in 1993 and the rise of the Eurasianist approach to Russian foreign policy, Russia gradually expanded its cooperation with its old neighbor, China. For nearly three decades, we have seen the strengthening of cooperation between the two countries and the expansion of areas of cooperation to the geopolitical and geoeconomic sectors. First, ending the border disputes was on the agenda of the two countries, and then political, economic, and ultimately security and military partners were put in place.
