The Sino-Vietnamese War was a short-lived conflict in early 1979 between the People's Republic of China and the Socialist Republic of Vietnam. This conflict was a response to the Vietnamese invasion and occupation of Cambodia led by the China-backed Khmer Rouge. In February 1979, China under Deng Xiaoping launched a surprise invasion of northern Vietnam, capturing several cities near the borders. On March 6th 1979 China declared their mission successful, as they forced Vietnam to back some forces out of Cambodia to go protect Hanoi. However, the Vietnamese occupation of Cambodia continued all the way into 1989 and Vietnam was able to oust Pol Pot out of Cambodia. Sino-Vietnamese relations weren't fully restored until 1991. China was trying to prove that the USSR wasn't able to protect its allies.

Background

Sino-Soviet Split

China and Vietnam have a long history. During the first Indochina war with France,China continued the mission of USSR to expand communism, therefor they aided Vietnam and became the connectors between USSR and Vietnam.

After the death of Joseph Stalin, the Sino-Soviet relations began to fall apart. Mao Zedong believed that Nikita Khrushchev made an error in his interpretation of marxism-leninism, and that he made a huge mistake denouncing Stalin in his secret speech. This led to the Sino-Soviet Split which then led to the lowering aid from China to Vietnam, because they didnt support the PRC against USSR.

In response to this falling apart, as many as million chinese troops were stationed along the Sino-Soviet border, getting ready for a full-scale war.

At the same time Vietnam was further distancing themselves from China by Increasing it's allignment with USSR and joining the CMEA (council for mutual economic assistance)

Following the death of Mao and the overthrowing of the Gang of Four and the rise of Deng Xiaoping, China revised their economy to be market oriented, denounced cultural revolution, and collaborated with USA against USSR.

Vietnam War

As France withdrew from Vietnam, and America started stepping in to support South Vietnam, the USSR and Vietnam became important allies.For PRC this was a disturbing development, because it would mean they could find themselves incircled in the Soviet sphere of influence.

After USA withdrew their forces from Vietnam and North completely invaded South and won, PRC started talks with USA (specifically with Henry Kissinger and later with Richard Nixon) which would see their foreign policy be re-oriented towards USA
