The story
From 1963 to 1966 Indonesia fought an undeclared conflict, called Konfrontasi, against the new Federation of Malaysia. President Sukarno called Malaysia a neo-colonial project to keep British power in Southeast Asia. Indonesian infiltrators crossed into Sarawak and Sabah in Borneo, and others raided the Malay peninsula and Singapore, where a bomb at MacDonald House in March 1965 killed three people. Britain committed troops from Britain, Australia and New Zealand, with Malaysian forces, and ran secret cross-border raids into Kalimantan, called Claret operations.
The war was fought by small patrols in thick jungle, with casualties in the hundreds. Sukarno also used the campaign to rally Indonesians during a bad economy and rising tension between the army and the communist party. After General Suharto took control in 1965 and 1966, Indonesia changed course, and a peace agreement was signed in Bangkok in August 1966. Konfrontasi's end opened the way to cooperation, and in 1967 Indonesia, Malaysia, Singapore, Thailand and the Philippines founded ASEAN.
Why it mattered
- The conflict ended with Malaysia intact and helped bring Suharto to power.
- It pushed Southeast Asian states to found ASEAN in 1967.
- It was a rare conflict in which British, Australian and New Zealand troops fought alongside Malaysian forces in jungle war.
- Its end restored Indonesia and Malaysia's relations.
