The CCP’s 11th Central Committee held its Third Plenum in Beijing, widely treated as the turning point that prioritized economic modernization and pragmatic policy over Cultural Revolution-era “class struggle,” consolidating Deng Xiaoping’s status as China’s paramount leader.
China began its large-scale border offensive against Vietnam, a short but consequential conflict occurring early in the reform era and intertwined with Deng’s efforts to assert strategic direction and influence over the PLA and foreign policy.
Zhao Ziyang replaced Hua Guofeng as Premier, bringing a leading reform-minded administrator to the top of the State Council and accelerating national rollout of rural and economic reforms associated with the early Deng era.
Deng Xiaoping replaced Hua Guofeng as Chairman of the CCP’s Central Military Commission, formalizing his control over the armed forces—an essential pillar of his paramount leadership during the reform era.
The CCP’s 12th National Congress met in Beijing and laid out a modernization-through-socialism program, consolidating the reform-era leadership lineup and policy direction associated with Deng’s collective leadership model.
The Third Plenum of the 12th Central Committee adopted a major “Decision on Reform of the Economic System,” marking a key step from rural experiments toward broader, city-centered restructuring and new thinking on planned and market mechanisms.
China and the United Kingdom signed the Joint Declaration in Beijing, setting the terms for Hong Kong’s 1997 handover and outlining “one country, two systems” arrangements—an important diplomatic milestone under Deng-era leadership.
Deng approved the proposal for the “863 Program” (State High-Tech Development Plan), a flagship effort to build indigenous capabilities in strategically important technologies during the reform-era push for modernization.
Student protests began in Hefei and expanded to major cities from December 1986 into January 1987, helping trigger an intra-leadership debate over political liberalization and contributing to the removal of Hu Yaobang as party chief.
Hu Yaobang was forced to step down as CCP General Secretary amid leadership criticism of his handling of the 1986–87 student protests, marking a key personnel shift within Deng-era collective leadership.
Hu Yaobang’s death catalyzed student-led demonstrations that grew into a nationwide movement demanding political reform and anti-corruption measures, creating the defining political crisis of the late Deng period.
Authorities imposed martial law in Beijing as leadership divisions deepened over how to respond to the demonstrations, setting the stage for the subsequent military crackdown.
Troops forcibly cleared protestors in Beijing on the night of June 3–4, 1989, ending the mass movement and reshaping the political trajectory of the reform era by tightening political controls while reform later resumed on economic lines.
Deng stepped down as Chairman of the CCP Central Military Commission, a significant leadership transition after the 1989 crisis (though he continued to exert paramount influence in Chinese politics).
Deng toured southern China (including Shenzhen, Zhuhai, Guangzhou, and Shanghai), delivering remarks that helped restart and strengthen market-oriented reforms after the post-1989 slowdown.
The CCP’s 14th National Congress formally set the objective of establishing a “socialist market economic system,” institutionalizing the direction that Deng had forcefully promoted in 1992.
