China and Indonesia established formal diplomatic relations in 1950, more commonly referred to as Sino-Indonesian relations. Prior to this, for many centuries, the two countries maintained a variety of relations mainly in informal trade. Under Sukarno’s presidency, from 1945 to 1967, relations with China deepened, as in the early 1960s Sukarno embarked on a series of aggressive foreign policies under the rubric of anti-imperialism and personally championed the Non-Aligned Movement. These developments led to increasing friction with the West and closer relations both with China and the USSR.

Suharto was an Indonesian military officer and politician, who served as the second and the longest serving President of Indonesia. Widely regarded as a military dictator by international observers, Suharto led Indonesia as an authoritarian regime from the fall of his predecessor Sukarno in 1967 until his resignation in 1998 following nationwide unrest. His 31-year dictatorship is considered one of the most brutal and corrupt of the 20th century, as he was central to the perpetration of mass killings against alleged communists, ethnic Chinese, irreligious people and trade unionists.
