China agrees to provide aid to North Vietnam - Aug 30, 1966 - HISTORY.com

Hanoi Radio announces that Deputy Premier Le Thanh Nghi has signed an agreement with Peking whereby the People’s Republic of China will provide additional economic and technical aid to North Vietnam. China had already been providing support to the Communists in Vietnam since the war against the French. When the U.S. became decisively involved after the Gulf of Tonkin incident, China increased the support to both North Vietnam and the insurgents in South Vietnam. It was this support and that provided by the Soviet Union that permitted the North Vietnamese to prosecute the war against South Vietnam and the U.S. forces there.
