Konfrontasi (Confrontation) with Malaysia 1963 to 1966, including the Dwikora command, the Borneo campaigns, the role of the PKI, and the consequences for the Indonesian economy

What this dot point is asking

NESA expects you to explain why Sukarno opposed the formation of Malaysia, how the Konfrontasi campaign was waged in Borneo and through diplomacy, and how it deepened the Indonesian economic crisis and PKI-army polarisation. Strong answers integrate the anti-imperialist rhetoric, the cross-border Borneo campaign, and the rapid Suharto-era de-escalation in 1966.

The answer

Origins: the Malaysia plan

British Prime Minister Tunku Abdul Rahman of Malaya proposed the Malaysia Federation on 27 May 1961, intended to combine Malaya, Singapore, and the British colonies of Sarawak, Sabah and Brunei. From the Indonesian perspective the plan extended British strategic influence around northern Borneo on Indonesia's doorstep, and protected British military bases (notably Singapore) for the long term.

The plan was endorsed by the Cobbold Commission (1962). Brunei elected to remain a separate sultanate. The Federation was scheduled to come into being in August 1963.

Sukarno's initial position was ambiguous. The MAPHILINDO meetings (Manila, June and July 1963) with President Macapagal of the Philippines (which had its own claim to Sabah) and the Tunku floated cooperative arrangements. But the rapid implementation, judged by Sukarno to bypass UN consultation he had been promised, and the formal proclamation of Malaysia on 16 September 1963, hardened Indonesian opposition. The Indonesian embassy in Kuala Lumpur was sacked the next day; the British embassy in Jakarta was burned on 18 September 1963.

The Brunei Revolt and early infiltration

The Brunei Revolt of 8 December 1962, led by A.M. Azahari of the Brunei People's Party and supported logistically by Indonesia, attempted to seize Brunei before the Federation came into being. British Gurkhas defeated the revolt within a week. Azahari fled to Manila. The revolt nonetheless showed that Indonesia was prepared to back armed action.

Cross-border infiltration into Sarawak and Sabah by Indonesian "volunteers," often supported by Indonesian Army and Marine units, began in 1963. The infiltrators worked with the Sarawak Chinese clandestine Communist organisations and exploited rural unrest. British Commonwealth forces responded with jungle counter-insurgency operations under General Walter Walker.

The Dwikora speech, May 1964

Sukarno escalated the campaign with the Dwi Komando Rakyat (Dwikora, Two People's Commands) speech of 3 May 1964. The two commands were to "heighten the revolutionary endurance of the Indonesian people" and to "assist the revolutionary struggle of the peoples of Malaya, Singapore, Sabah, Sarawak, and Brunei to dissolve the puppet state of Malaysia."

The Sukarelawan (volunteer corps) was mobilised. The slogan "Ganyang Malaysia" (Crush Malaysia) became the public face of the campaign. Mass rallies, including PKI-led ones, marched on Western embassies.

The Borneo campaign

The military phase ran along the 1,500-kilometre border between Indonesian Kalimantan and British Borneo (Sarawak and Sabah). Indonesia infiltrated regular Army and Marine units, KKO Marines, RPKAD paratroops (Indonesian Army special forces), and Air Force paratroops alongside locally recruited "volunteers."

The Commonwealth response, codenamed Operation Claret from 1964, authorised secret cross-border operations of up to 10,000 yards into Indonesian territory by British SAS, Australian SAS, New Zealand, Gurkha and Malaysian forces. These were tightly controlled, kept secret for decades, and proved effective at disrupting Indonesian staging.

Two Indonesian raids on the Malayan peninsula failed conspicuously. Indonesian paratroops landed at Labis (Johor) in August 1964 and at Pontian (south-west Johor) on 17 August 1964; all were captured or killed. The raids drew Australia formally into Konfrontasi, contributing 3rd Battalion Royal Australian Regiment and Special Air Service Regiment squadrons.

Casualties were comparatively modest. British and Commonwealth forces lost around 114 killed; Indonesia lost around 600 killed (estimates vary). The Indonesian operational tempo was real, but the political effort outran the military capacity.

Diplomatic isolation

Konfrontasi cost Indonesia diplomatically. Malaysia was elected to a non-permanent seat on the UN Security Council on 30 December 1964. Sukarno responded on 7 January 1965 by withdrawing Indonesia from the United Nations, the only state ever to do so. Indonesia further established (with China) a "Conference of New Emerging Forces" as an alternative; this collapsed after Sukarno's fall.

The Soviet Union supplied modern arms but grew anxious about the campaign. China provided rhetorical support and was the principal external backer of the PKI's "fifth force" proposal. The US, briefly tolerant under Kennedy, hardened under Johnson; AID and military assistance was suspended.

Economic and political cost

Defence absorbed up to 75 per cent of state expenditure in 1964 to 1965. Inflation reached 600 per cent in 1965. Foreign-owned enterprises were nationalised: British in 1963 to 1964 (around 300 estates and trading houses), American in 1965. The rupiah ceased to function as a stable currency.

Politically, Konfrontasi sharpened the army-PKI cleavage. The PKI demanded a "fifth force" of armed workers and peasants alongside the four military services, framed as a Konfrontasi necessity. The army (Generals Yani, Nasution) saw the proposal as a route to its own destruction. Konfrontasi thus became one of the proximate causes of the 30 September 1965 coup attempt.

The end of Konfrontasi, 1966

After the 30 September coup attempt and Suharto's rise to operational power, the army moved quickly to wind up the campaign. Foreign Minister Adam Malik met Tun Razak in Bangkok on 28 May to 1 June 1966 and signed the Bangkok Accord. The formal Treaty was signed in Jakarta on 11 August 1966. Diplomatic relations were restored. Indonesia rejoined the UN on 28 September 1966.

The diplomatic reversal helped consolidate the New Order's foreign policy. ASEAN was founded on 8 August 1967 with Indonesia as a founding member alongside Malaysia, Singapore, Thailand and the Philippines.

Historiography

J.A.C. Mackie (Konfrontasi: The Indonesia-Malaysia Dispute 1963-1966, 1974) is the standard work. He treats Konfrontasi as the necessary expression of Sukarno's "revolutionary state" and as a strategic miscalculation by Sukarno of British and Commonwealth resolve.

Harold Crouch (The Army and Politics in Indonesia, 1978) treats Konfrontasi as the catalyst that forced the army-PKI confrontation by raising the stakes of mass mobilisation.

Peter Dennis and Jeffrey Grey (Emergency and Confrontation, 1996, Australian official history) is the standard Australian military account.

M.C. Ricklefs (A History of Modern Indonesia) emphasises the domestic balancing function: Konfrontasi let Sukarno keep both the army and the PKI on the same side of a foreign policy crisis.

How to read a source on this topic

First, distinguish the official Indonesian framing ("anti-neo-colonial struggle") from the strategic substance (a campaign against a state with much greater logistical depth in a theatre where Indonesian air and sea reach was limited). The rhetoric was the campaign's main weapon.

Second, weigh the role of the PKI. Aidit and the PKI did not invent Konfrontasi, but they used it. The "fifth force" demand was the most consequential domestic political proposal of the period.

Third, note the speed of de-escalation in 1966. Once Suharto had the army, the campaign ended within months. This is evidence that Konfrontasi had been Sukarno's project, sustained against army scepticism.

Common exam traps

Treating Konfrontasi as a war. Both sides avoided the framing, and the military scale was small (around 600 Indonesian deaths). The political and economic effects far outran the combat scale.

Confusing Trikora and Dwikora. Trikora (December 1961) launched the West Irian campaign. Dwikora (May 1964) launched the escalation of Konfrontasi.

Forgetting Australia. Australian SAS and 3RAR played important roles, and the campaign hardened Australian foreign-policy thinking on Southeast Asia for the rest of the decade.

Missing the speed of resolution. Konfrontasi was ended by Suharto, not by Sukarno; the Bangkok Accord of June 1966 is part of the New Order story.

In one sentence

Konfrontasi from 1963 to 1966, launched by Sukarno's Dwikora speech against the British-sponsored Federation of Malaysia and fought as a low-intensity cross-border campaign in Borneo, drove Indonesia out of the UN, absorbed up to 75 per cent of state expenditure, and was wound up in months by Suharto after the September 1965 coup attempt.
