Cluster Munition Ban Policy

Last updated: 05 September 2023

Summary: Signatory Indonesia has pledged to ratify the Convention on Cluster Munitions, but has not taken any steps to do so, aside from holding stakeholder consultations. Indonesia participated in a meeting of the convention most recently in September 2021. It voted in favor of a key United Nations General Assembly (UNGA) resolution promoting universalization of the convention in December 2022.

Indonesia states that it has never used, produced, or exported cluster munitions, but has acquired them in the past and possesses a stockpile.


The Republic of Indonesia signed the Convention on Cluster Munitions on 3 December 2008.

Indonesia has not taken any steps to ratify the convention, aside from holding stakeholder consultations.[1] Government officials have expressed their desire for Indonesia to ratify the convention, but the ratification request has not been sent to the national parliament for consideration and approval.[2]

Indonesia participated in the Oslo Process that created the Convention on Cluster Munitions, and was one of the strongest supporters of a comprehensive ban on the weapons.[3] Indonesia hosted a regional conference on the convention in Bali in November 2009.

Indonesia has participated in several meetings of the convention, most recently the Second Review Conference held in November 2020 and September 2021. Indonesia was invited to, but did not attend, the convention’s Tenth Meeting of States Parties held in Geneva in August–September 2022.[4] Indonesia has attended regional workshops on the convention in the past.

In October 2022, Indonesia delivered a statement at the UNGA on behalf of the Non-Aligned Movement (NAM) that recognized “the adverse humanitarian impact caused by the use of cluster munitions” and expressed “solidarity with the cluster munitions-affected countries.”[5] The statement called for “financial, technical and humanitarian assistance to unexploded cluster munitions clearance operations” as well as “full access of affected countries to material, equipment, technology and financial resources for unexploded cluster munitions clearance.” It also highlighted the importance of the “social and economic rehabilitation of victims” of cluster munitions.

In December 2022, Indonesia voted in favor of a key UNGA resolution urging states outside the Convention on Cluster Munitions to “join as soon as possible.”[6] Indonesia has voted in favor of the annual UNGA resolution promoting the convention since it was first introduced in 2015.

Indonesia is a State Party to the Mine Ban Treaty. It is not party to the Convention on Conventional Weapons (CCW).

Use, production, and transfer

Indonesia has stated that it has never used, produced, or exported cluster munitions.[7]


Indonesia acquired cluster munitions in the past and possesses stocks, but has not shared information on the types and quantities stockpiled.[8]

Jane’s Information Group reported in 2004 that Indonesia possesses United States (US)-made Rockeye cluster bombs.[9] In 2016, the Indonesian Marine Corps took possession of 122mm Type-90B surface-to-surface rocket launchers, but it is not known if the ammunition used for these weapons includes versions with submunition payloads.[10]

In June 2020, Indonesia received a shipment of 36 Brazilian-made ASTROS II Mk. 6 multi-barrel rocket launchers, capable of firing SS-60 and SS-80 300mm surface-to-surface rockets or SS-150 450mm rockets.[11] The SS-60 and SS-80 rockets can be equipped to deliver either a unitary high explosive warhead or multiple submunitions.[12] The payload version for the ASTROS II rocket launchers acquired by Indonesia is not known. Indonesian officials have never responded to requests from the Cluster Munition Coalition (CMC) to clarify this question.[13]
