On the one hand, the Sino-Indian border war, Sino- Soviet hostile relations and the US-China rivalry and on the other hand, Pak-India enmity, Pak-Soviet hostility and Pakistan’s disillusionment with the US brought China and Pakistan closer to each other. China was in struggle to get membership in United Nations where the Western powers were blocking its way and Taiwan was allowed to be a Chinese nation representative. In 1960s, Pakistan abandoned its policy of following the West and voted for Communist China in the UN. China too refrained from its policy of neutrality regarding Indo-Pak issues and openly started to support Pakistan on Kashmir issue. Beijing supported Islamabad in its war with New Delhi. China condemned Indian aggression against Pakistan and appreciated the Kashmiri freedom fighters in their struggle from Indian illegal occupation. This paper covers discussion and analysis on China’s seat in UN, Kashmir issue and Indo-Pak war of 1965.
