Read the following passage carefully and answer the questions based on it :
‘‘After the Chinese revolution, India was one of the first countries to recognise the communist government. Nehru felt strongly for this neighbour and helped the new government in international fora. A joint enunciation of peaceful coexistence was signed by Indian Prime Minister and the Chinese premier in 1954. But two developments strained this relationship. China annexed Tibet and removed a historical buffer between the two countries. A little earlier, a boundary dispute had surfaced between India and China.’’
