In 1977, a serious crisis broke out with Cambodia, which had adopted a pro-Chinese line, and there were bitter clashes in the “Duck Beak” region.

In December 1978 Viet Nam invaded Cambodia and in the following January, deposed Pol Pot, installed the pro-Soviet Hen Samrin in power. In February 1979, China launched a punitive attack on Viet Nam. The hostilities lasted about a month: the peace talks began in April, but did not produce significant results. In 1986, according to a2zdirectory, the troops of Hanoi had not yet been withdrawn from Cambodia, where the Khmer resistance was raging more than ever.. In bad relations with China and with all the ASEAN countries, Viet Nam remained closely linked to the USSR, with which in November 1978 it had signed a treaty of friendship and cooperation.

From June 1978 Viet Nam also became a member of COMECON, an intergovernmental organization that dissolved on June 28, 1991. Since the constitution of the Socialist Republic of Viet Nam (1976), the most important political figure in the country has been Le Duan, general secretary of Dan Cong san Viet-Nam (the local Communist Party). Upon his death (1986), important changes were made with the appointment of Nguyên Van Linh as party general secretary, Pham Hung as prime minister and Vo Chi Cong as head of state. Significantly preceded by a popular pre-consultation for the choice of candidates in the same 1987 political elections, this renewal soon had significant consequences such as a rapprochement with the church, a gradual economic liberalization and political and economic openings towards China, the United States and Japan, destined to consolidate in the following years in parallel with the disengagement in Cambodia, completed at the end of 1989 and finalized with the peace agreement of October 1991. In the same year the Communist Party, during the VII National Congress, elected Du Muoi as its general secretary (June), thus indirectly determining the passage of the office of prime minister to Vo Van Kiet (August). This reconfirmed the reformist orientation that in April 1992 resulted in the promulgation of a new Constitution (with the assignment of greater powers to the president), as well as in a more decisive economic liberalization and in the more determined search for forms of regional cooperation. Still in the same year, Viet Nam obtained from reformist orientation which in April 1992 resulted in the promulgation of a new Constitution (with the assignment of greater powers to the president), as well as in a more decisive economic liberalization and in the more determined search for forms of regional cooperation.

Still in the same year, Viet Nam obtained from ASEAN observer status. Still in a one-party system, also preserved by the new constitutional document, the political consultations of July 1992 were carried out: the newly elected National Assembly, largely renewed, for the first time directly chose the head of state, indicated in General Lê Duc Anh (September 23), former defense minister. July 1995 brought some important changes in Vietnam’s history: the country’s full entry into ASEAN and the reestablishment of good diplomatic relations with the United States. The awareness of a profound generational change underway in the country, with more than half of the population born after reunification (1975), led the management team to cautious openings, albeit alternating with strict repressions, which materialized in the 1997 elections, in which the leadership group (Le Duc Anh, president of the Republic; Vo Van Kiet, prime minister; Do Muoi, party secretary) did not reappear. In their place were elected respectively Tran Duc Luong, Phan Van Khai and Le Kha Phieu.
