Sihanouk's nonaligned foreign policy, which emerged in the months following the Geneva Conference, cannot be understood without reference to Cambodia's history of foreign subjugation and its very uncertain prospects for survival as the war between North Vietnam and South Vietnam intensified. Soon after the 1954 Geneva Conference, Sihanouk expressed some interest in integrating Cambodia into the framework of the Southeast Asia Treaty Organization (SEATO), which included Cambodia, Laos, and South Vietnam within the "treaty area", although none of these states was a signatory. But meetings in late 1954 with India's Prime Minister Jawaharlal Nehru and Burma's Premier U Nu made him receptive to the appeal of nonalignment. Moreover, the prince was somewhat uneasy about a United States-dominated alliance that included one old enemy, Thailand, and encompassed another, South Vietnam, each of which offered sanctuary to anti-Sihanouk dissidents.
