The International Agreement on the Neutrality of Laos is signed.

The International Agreement on the Neutrality of Laos was signed in Geneva on 23 July 1962 as the culmination of an international conference aimed at preventing Laos from becoming a battleground in the Cold War. Fourteen nations, including the United States, the Soviet Union, China, the United Kingdom, France, North Vietnam, and South Vietnam, agreed to respect the independence, sovereignty, territorial integrity, and permanent neutrality of Laos. The agreement followed years of civil war between the Royal Lao Government, the communist Pathet Lao movement, and neutralist factions, which had drawn in foreign military and political support. It called for all foreign troops, military advisers, and personnel to leave Laos and prohibited any nation from using Laotian territory for military purposes or interfering in the country’s internal affairs.

Although the agreement briefly reduced tensions, it proved difficult to enforce. Both the United States and North Vietnam continued to view Laos as strategically important, while the Pathet Lao retained close ties to Hanoi. North Vietnamese forces remained in eastern Laos, where they developed and protected sections of the Ho Chi Minh Trail, a vital supply route into South Vietnam. In response, the United States expanded covert operations in Laos, including support for anti-communist forces and an extensive secret bombing campaign. As the Vietnam War intensified, the neutrality of Laos became increasingly nominal, and the country remained embroiled in conflict until the communist Pathet Lao seized power in 1975, bringing an end to the Laotian Civil War and establishing the Lao People’s Democratic Republic.
