In contrast to Sukarno's anti-imperialistic antipathy to western powers and tensions with Malaysia, Indonesia's foreign relations since the Suharto "New Order" have been based on economic and political cooperation with Western nations.[74] Indonesia maintains close relationships with its neighbors in Asia, and is a founding member of ASEAN and the East Asia Summit.[69] The nation restored relations with the People's Republic of China in 1990 following a freeze in place since anti-communist purges early in the Suharto era.[72] Indonesia has been a member of the United Nations since 1950,[75] and was a founder of the Non-Aligned Movement (NAM) and the Organisation of the Islamic Conference (OIC, now the Organisation of Islamic Cooperation).[69] Indonesia is signatory to the ASEAN Free Trade Area agreement, the Cairns Group, and the WTO, and has historically been a member of OPEC, although it withdrew in 2008 as it was no longer a net exporter of oil. Indonesia has received humanitarian and development aid since 1966, in particular from the United States, western Europe, Australia, and Japan.[69]
