In 1959, Ayub Khan's interest in building defence forces already diminished when he made an offer of joint defense with India during the Sino-Indo clashes in October 1959 in Ladakh, in a move seen as a result of American pressure and a lack of understanding of Foreign affairs Upon hearing this proposal, India's Prime Minister Nehru reportedly counter-ask "Defence Minister Ayub: Joint Defence on what?." India remained uninterested with such proposal and Prime Minister Nehru decided to push his country's role in the Non-Aligned Movement In 1960, President Ayub signed the water treaty with Prime Minister Nehru that was facilitated by the World Bank as its witness. In 1962, after India was defeated by China, Ayub Khan disguised a few thousand soldiers as guerillas and sent them to Indian Kashmir to incite the people to rebel. In 1964, the Pakistan Army engaged with Indian Army in several skirmishes, and a secretive operations began to place around that time.
