Kenneth Galbraith questioned Nehru on how they could avoid American militarization of Vietnam. Nehru remained ambiguous on Vietnam but emphasized that "the United States must stay out". According to his nephew and then-Indian Ambassador to the US Braj Kumar Nehru, the Prime Minister later told Foreign Secretary M. J. Desai, "Tell them, tell them not to go into Vietnam. They will be bogged down and they will never be able to get out." President Rajendra Prasad visited North Vietnam in 1959. Prasad met with Ho Chi Minh and gifted him a bodhi tree (ficus religiosa) which they planted at the Tran Quoc Pagoda, the oldest Buddhist temple in Hanoi. It is the first bodhi tree in Vietnam, and has since become a symbol of friendship between the two countries. On 22 December 2019, the Buddhist Sangha of Vietnam and the Embassy of India in Hanoi held a ceremony to mark the 60th anniversary of the tree's planting. During Indian President Pranab Mukherjee's visit to Vietnam in September 2014 he gifted a second bodhi tree to President Truong Tan Sang which they planted at the Presidential Palace in Hanoi. India established diplomatic relations with North Vietnam on 7 January 1972, a year before the US withdrawal from Vietnam and three years before the Fall of Saigon. India supported the reunification of Vietnam and the two countries have maintained friendly relations, especially in wake of Vietnam's disputes with China, with whom India also has disputes.
