On September 15, 1965, Mr. B. K. Nehru, India's Ambassador to the United States, told the National Press Club in Washington, D.C.: “What seems impossible to deny is that the Chinese and the Pakistanis are working in the closest possible co-operation to increase the military and economic pressure on India and to encourage internal disorder with a view to weakening, and if possible causing the break-up of, the Indian Union.” There has indeed been evidence of Sino-Pakistani co-operation in recent years, though the use of the words “closest possible” might be questioned. Strangely enough the United States, by her arms aid to India since 1962, became at least partly responsible for one of the more successful phases of Chinese Communist diplomacy since the inception of the People's Republic in 1949.
