The war began in February due to political conflict between two sides, especially with Indochinese accession to the COMECON and the South China Sea conflict, which is disputed since 1968, during the height of Cultural Revolution in China and political liberalization in Indochina. At first, it was settled as a free zone but after that, multiple naval wars occur, of which the Indochinese secured its' naval area.

The impact of the war deeply strained the Sino-Indochinese relations, even after restoring relations in 1985, during the beginning of political re-liberalization (restoring the liberal reforms of 1965), and further making the Vietnamese part of the Indochina to be more Sinophobic, which indirectly triggered the 2014 all-Indochina protests, which further fastened the modernization of the National Army and making the National Militia an active reserve force of the Armed Forces, further strained relations despite having a "strategic" relations.

Prelude

The government of Vietnamese-dominated Indochina was in the phase of changing diplomatic stances with the Chinese, considering the mutual invasion and military conflict, and ideological differences. While the Indochinese government wanted a lesser pro-Soviet approach combining with some Western cooperation, a resemblance of Romania's foreign policy under Gheorghiu-Dej. Ideological conflicted was sparkled due to implementation of nationalism within the Socialist Party and the semi-rubber stamp National Assembly.

There's also another military modernization of the Indochinese Army, combining weapons from the Soviet Union, the United States and also including China.
