In July 1973, the Central Committee of the Communist Party of Vietnam after its 21st conference issued a resolution of strengthening the armed forces to unify the country. In executing the issue, three months later the Ministry of Defence and the Military Commission of the Central Committee approved the plan of organising regular army corps for the Vietnam People's Army. On 26 March 1975,[1] General Võ Nguyên Giáp, Minister of Defence, signed the edict that led to the establishment of the 3rd Corps in Tây Nguyên, from which came the name Tây Nguyên Corps of the unit.[2] The first headquarters of the corps consisted of party committee secretary (bí thư) Đặng Vũ Hiệp and commander (tư lệnh) Vũ Lăng.
On 13 September 2024, the plan to merge the 3rd and 4th Corps to form the 34th Corps was announced in the 3rd Corps Emulation Congress.[3] The corps was disbanded on 7 December 2024 to form the 34th Corps.[4]
