中共與印度曾都是不結盟國家的領導者，但1962年的邊界戰爭完全改變了原有的關係。冷戰後因為雙方國力發展的需要，不斷的透過高層互訪尋求改善，重申通過去平等協商，公正合理的「和平共處五原則」以及雙方都能接受的邊界問題解決方案。同時，印度也首度承認「西藏自治區」是中共領土的一部分，中共也承認錫金主權屬印度所有，並逐步發展出以經貿、文化、科技為主軸的合作關係。 蘇聯瓦解、兩極體系不復存在，起而代之的是多極的區域霸權，彼此的外交關係，均以南亞爭奪為中心，防範對方成為此區域強權；除了透過外交互動、經貿以及軍事合作，希冀維持和諧關係，也在印度洋、巴基斯坦及能源等問題上相互競爭，因兩國在各方面的競、合，也對區域內美、俄、日等大國形成不同程度的影響。 本論文主要是藉由地緣政治及歷史等研究途徑，透過文獻分析與比較分析法，研究、分析中、印關係發對亞太安全之影響，並就事件發生，歸納雙方未來可能的交往模式與彼此關係。 China and India were once the leaders of the “Non-Allied Countries” until the border conflict, which took place in 1962, changed the relationship between two countries. However, due to the necessity of developing national power post Cold War, both China and India had continuously exploit the opportunities to improve the relationship between two countries by high official visits to each other, reclaim the “Panchshell” and a peaceful resolution of the border issue. India took the initiative by recognizing Tibet Autonomous Region is part of China’s territory. China on the other hand, recognized Sikkim belongs to India. Both countries gradually built a cooperative relationship focus on economy, culture and technology exchange. The Bi-Polar sovereignty vanished with corruption of Soviet Union. The Multi-Polar region hegemony rose with the common diplomatic concern: striving for the dominance in South Asia and block other side to become regional hegemony.

On the other hand, they are fighting over issues concerning Indian Ocean, Pakistan and energy resource. The cooperation and competition between these two countries had various impacts on other countries like United States, Russia and Japan. The intent of the research is to increase the readers’ understanding of how relationship between China and India might affect the security of Asia-Pacific region. By implementing analysis of archives and studies of geopolitics and history, conclusion can be drawn to indicate the possible interactive pattern and relations of these two countries.
