China and Soviet Union recognize Democratic Republic of Vietnam - Jan 18, 1950 - HISTORY.com

People’s Republic of China formally recognizes the communist Democratic Republic of Vietnam and agrees to furnish it military assistance; the Soviet Union extended diplomatic recognition to Hanoi on January 30. China and the Soviet Union provided massive military and economic aid to North Vietnam, which enabled North Vietnam to fight first the French and then the Americans. Chinese aid to North Vietnam between 1950 and 1970 is estimated at $20 billion. It is thought that China provided approximately three-quarters of the total military aid given to Hanoi since 1949, with the Soviets providing most of the rest. It would have been impossible for the North Vietnamese to continue the war without the aid from both the Chinese and Soviets.
