At the Sixth National Congress of the Communist Party of Vietnam (CPV) in December 1986, reformist politicians replaced the "old guard" government with new leadership. The reformers were led by 71-year-old Nguyễn Văn Linh, who became the party's new general secretary. He and the reformers implemented a series of free-market reforms known as ("Renovation") that carefully managed the transition from a planned economy to a "socialist-oriented market economy". Though the authority of the state remained unchallenged under "Đổi Mới", the government encouraged private ownership of farms and factories, economic deregulation, and foreign investment, while maintaining control over strategic industries. The Vietnamese economy subsequently achieved strong growth in agricultural and industrial production, construction, exports, and foreign investment, although these reforms also caused a rise in income inequality and gender disparities.
