In today's world, great power politics is the leading force leading the changes of the global geopolitical system. In a sense, the geopolitical system is also the spatial distribution of political power of big countries. The reason why a big country is a big country lies not only in its total material quantity, but also in the power that these materials can transform and the total space they play. Pupils all know to draw a line between two desks, no one can have more and no one can have less. So is the country. From/kloc-the Vienna Conference in the 0/9th century to the Paris Peace Conference and Yalta Conference in the 20th century, it was a meeting to divide the geographical space of the victorious countries. At the Yalta Conference, Churchill and Stalin exchanged their spheres of influence in Europe, and all the participants understood this truth. This is not pleasant to say, but it is an old fact. It should be noted that the division of geopolitical space of big countries has always been the result of military contests rather than verbal quarrels, which has not changed much compared with the animal kingdom.
Taiwan Province Province is not yet unified in China, and it is also the frontier base of the East China Sea for China to enter and exit the Pacific Ocean and realize its sea power interests. By unifying Taiwan Province Province, China has completely broken through the chain around the island that the United States has built in the western Pacific since the Cold War to block China, which is more significant than the acquisition of Hawaii by the United States. Unifying Taiwan Province Province and North China can curb the possibility of Japanese military coveting Northeast China again. South Korea and Hainan Province form a huge pincer to protect China's Nansha sovereign island, thus effectively ensuring China's maritime security through the Straits of Malacca; The western region can expand the safe space in the southeast of China and form the pioneer treasury of the gold economic belt in the southeast coast of China. China's unification process is also consistent with China's sea power realization process, which determines that the unification of Taiwan Province Province is an unavoidable threshold for China's development. Taiwan Province Province does not recover, and Nansha does not recover. If the key to geopolitics in the South China Sea is the Straits of Malacca, then for China, the Nansha Islands within China's sovereignty are the key to China's realization of China's sea power interests in the South China Sea. As a big country, China must have its own offshore base in the South China Sea. If Diaoyu Island and Taiwan Province Province return to the motherland, China's security interests in Northeast Asia and Southeast Asia will be guaranteed.
