The United States suspends the Commercial Import Program in response to repression of the Buddhist majority by the regime of President Ngo Dinh Diem.

The Commercial Import Program, sometimes known as the Commodity Import Program (CIP), was an economic aid arrangement between South Vietnam and its main supporter, the United States. It lasted from January 1955 until the Fall of Saigon in 1975 and the dissolution of South Vietnam following the invasion by North Vietnam after US forces had withdrawn from the country due to the 1973 cease-fire agreement.

The Buddhist crisis was a period of political and religious tension in South Vietnam between May and November 1963, characterized by a series of repressive acts by the South Vietnamese government and a campaign of civil resistance, led mainly by Buddhist monks.
