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Fall of Saigon in 1975 and the dissolution of South Vietnam following the invasion by North Vietnam after US forces had withdrawn from the country after the 1973 cease-fire agreement. The initiative was a trading plan that was designed to inject large amounts of American capital into the South Vietnamese economy to help fuel its industrialisation, growth and self-sufficiency, without incurring the high levels of inflation that would normally occur in such a drastic injection of money.
