When Sukarno was overthrown by General Suharto, relations between the two states deteriorated, likely due to Indonesia's anti-communist policy under Suharto following the 1965 unrest and mass murder of thousands of leftists. However, unlike relations with China during Suharto's rule, diplomatic relations were not suspended and remained intact. During this time, Indonesia is also one of many countries that boycotted the 1980 Summer Olympics held in Moscow. Relations had been reported to be deteriorated further during the early days of Suharto's presidency due to widespread ideological stigma, and Indonesia became increasingly pro-Western in foreign and economic relations at the time.
