Indonesia–Malaysia Confrontation



The Indonesia-Malaysia Confrontation, or Konfrontasi, lasted from 1963 to 1966.1 The conflict was an intermittent war waged by Indonesia to oppose the formation and existence of the Federation of Malaysia.2 It was marked by a breakdown in political, economic and social relations that eventually led to armed incursions, bomb attacks, and acts of subversion and destabilisation.3

Background
The proposal for a Federation of Malaysia was first announced in May 1961. The proposal sought to merge Malaya, Singapore and British colonies in Borneo, namely North Borneo (Sabah), Sarawak and Brunei.4 Indonesia initially did not raise any objections. Its opposition to the proposal came after the outbreak of the 1962 Brunei revolt.5

Several reasons were put forward for Indonesia’s opposition to the formation of Malaysia.6 One was that Indonesia regarded the Federation as having a neo-colonial status contrary to that of revolutionary Indonesia, especially in light of the fact that Britain would continue to have military bases in Malaya and Singapore.7

The beginning of Confrontation
In December 1962, Brunei faced a revolt by the North Kalimantan National Army (Tentera Nasional Kalimantan Utara), which was pushing for the independence of Brunei instead of its joining the Federation.8 In response to the revolt, British troops were sent from Singapore to Brunei, where they crushed the revolt within days. During the last days of the revolt, Indonesia began issuing statements in support of the uprising which culminated in a heated exchange between Indonesia and Malaysia.9 On 20 January 1963, the Indonesian Foreign Minister announced a policy of confrontation towards Malaya in economic and social relations. While there were intermittent attempts at reaching a political understanding, Indonesian troops began engaging in raids, sabotage and attempted subversion in Sarawak and Sabah.10


In May 1963, President Sukarno and Tunku Abdul Rahman held talks and agreed that a plebiscite would be held before the Federation was formed. Sukarno agreed that Indonesia would not stand in the way if the people of North Borneo supported the Federation. However, the Tunku proceeded to sign the London Agreement on 9 July, in which it was settled that the Federation of Malaysia would be formed on 31 August 1963. Talks in Manila between the two countries from 30 July to 5 August helped to diffuse tensions. However, when it was announced on 29 August that the Federation of Malaysia would be formed on 16 September, Indonesia saw it as a breach of faith.11 On 16 September, the Federation was formed but Brunei decided not to join it.12 In response, on 25 September 1963, President Sukarno announced a ganyang Malaysia or “Crush Malaysia” campaign.13

Confrontation escalated to open cross-border military attacks in Sabah and Sarawak14 By 1964, Indonesia had begun raids in Singapore and the Malaysian Peninsula.15 To repulse infiltrators and prevent incursions, British, Gurkha and other Commonwealth troops remained at the request of Malaysia. Together with the Malay battalions, they engaged in successful offensives against the Indonesian troops.16 In June and July 1964, Indonesian army units infiltrated Singapore with instructions to destroy transportation and other links between the island and the state of Johore. It was also suspected that they were behind the September 1964 communal riots in Singapore.17 Singapore was also hit by a wave of bombings that culminated in the bombing of MacDonald House that killed two people and injured 33 others.18

The end of Confrontation
In 1965, internal strife broke out in Indonesia. From 30 September to 2 October 1965, the Indonesian army crushed an attempted coup by the Indonesian Communist Party (PKI).19 This was followed by a massacre of PKI members, such that by March 1966, Sukarno, whose support base lay with the PKI, was forced to transfer power to General Suharto. The latter became Indonesia’s de facto political leader. Sukarno was put under house arrest and Suharto was formally installed as president.20 Suharto ended the Confrontation, signed a peace treaty with Kuala Lumpur on 11 August 1966, and re-established normal relations with Malaysia and Singapore.21
