United Nations Temporary Executive Authority and United Nations Security Force in West New Guinea

Between 1 October 1962 and 1 May 1963, Western New Guinea was administered by a body created by the GA with the consent of the parties involved, UNTEA, the first time the UN had assumed direct administrative responsibility for a territory. UNTEA’s governance was also facilitated by the GA-authorized UNSF of armed peacekeepers that helped maintain law and order.

Following the Dutch recognition of Indonesia’s independence in 1949, a dispute remained over the status of Western New Guinea. Indonesia claimed the territory as part of its new State. The Netherlands initially argued that the territory should remain under Dutch governance as Dutch New Guinea, but by 1951, it had taken increasing measures to prepare the territory for eventual independence – to be governed by neither Indonesia nor the Netherlands.¹ There were several GA resolutions on the matter between 1954 and 1957, but the dispute persisted and early proposals for a form of UN trusteeship were rejected by Indonesia.² SC action to resolve the issue was unlikely given differing support between the permanent five members for the opposing sides.³

By 1960, both parties had strengthened their military position in the region, and a naval clash between Indonesian and Dutch forces in January 1962 highlighted how far the situation had escalated.⁴ This deteriorating situation, combined with increasing tensions over Vietnam, raised alarms about the overall security situation in East Asia and led to greater pressure on the Dutch to relax their claims.⁵ On 15 August 1962, Indonesia and the Netherlands signed the Agreement Concerning West New Guinea (West Irian),⁶ which provided for the eventual transfer to Indonesia of the disputed West Irian territory in West New Guinea following an interim administration by the UN.

As stipulated in the Agreement, following its signature, Indonesia and the Netherlands sponsored a draft resolution in the GA that would take note of the Agreement’s terms. This resolution passed in September 1962 (A/RES/1752(XVII)) by a vote of 89 to none, with 14 abstentions. The resolution not only took note of the Agreement’s terms but authorized the Secretary-General to carry out the tasks set out in the Agreement (ibid.). These included those tasks necessary to create and mobilize UNTEA under the direction of a UN administrator appointed by the Secretary-General.⁷ The Agreement also provided that the Secretary-General could “provide the UNTEA with such security forces” as deemed necessary to maintain law and order, what would later be known as the UNSF.⁸ The Secretary-General was to periodically report back on UNTEA’s progress and developments both to the parties themselves and the GA.⁹ In addition to the creation of UNTEA, both parties agreed to an initial ceasefire period, with a ceasefire observation team overseen by the Secretary-General.¹⁰

This decision by the GA is important for the precedent it set. It is seen as a precursor for subsequent UN administrations in East Timor and Kosovo, albeit not established by GA action.
