Indonesia–Malaysia–Thailand Growth Triangle

Attempt at economic liberalisation and integration in ASEAN From Wikipedia, the free encyclopedia

The Indonesia–Malaysia–Thailand Growth Triangle (IMT-GT) is a subregional economic cooperation framework established to accelerate economic transformation, enhance connectivity, promote balanced growth and strengthen cooperation among its member provinces and states. It was officially established in 1993 by Indonesia's President Soeharto, Malaysia's Prime Minister Mahathir Mohamad, and Thailand's Prime Minister Chuan Leekpai, representing one of ASEAN’s earliest initiatives to promote cross-border economic integration.

Anchored on shared geography, culture, and economic complementarities, IMT-GT fosters private-sector-driven integration and people-centered development across borders. It seeks to stimulate sustainable and inclusive development across 35 provinces and states within the three participating countries, an area covering approximately 683,300 km² and home to over 96 million people.

Geographical Coverage

The IMT-GT consists of:

Indonesia – 10 provinces in Sumatra: Aceh, Bangka Belitung Islands, Bengkulu, Jambi, Lampung, North Sumatra, Riau, Riau Islands, South Sumatra, West Sumatra.
Malaysia – 11 states in Peninsular Malaysia: Johor, Kedah, Kelantan, Melaka, Negeri Sembilan, Pahang, Penang, Perak, Perlis, Selangor, Terengganu.
Thailand – 14 southern provinces: Chumphon, Krabi, Nakhon Si Thammarat, Narathiwat, Pattani, Phang Nga, Phatthalung, Phuket, Ranong, Satun, Songkhla, Surat Thani, Trang, Yala.

History

The concept of IMT-GT emerged in the early 1990s, during a period of trade liberalisation and growing intra-Asian economic cooperation. Recognising the potential of geographically proximate regions to collaborate, the three governments formalised the initiative in 1993 to foster economic complementarity, connectivity, and private sector growth.

What began in 1993 as a bold idea to connect neighbouring regions across Indonesia, Malaysia, and Thailand has grown into one of Southeast Asia's most enduring subregional cooperation platforms. Starting with just 12 states and provinces, the Indonesia–Malaysia–Thailand Growth Triangle (IMT-GT) was founded on a simple but powerful belief: that shared geography and cooperation could unlock shared prosperity.

Early momentum followed quickly. With the Asian Development Bank coming on board in 1994, IMT-GT strengthened its foundations through the creation of key institutions, including the Joint Business Council to amplify private sector voices and the University Network to harness knowledge, research, and talent across borders.

As cooperation deepened, IMT-GT moved from vision to action. Landmark moments such as the First IMT-GT Summit in 2005 and the launch of the Chief Ministers’ and Governors’ Forum brought political leadership and subnational governments to the forefront. The introduction of Economic Corridors in 2007 marked a shift towards spatial, corridor-based development that connected cities, ports, and communities across the subregion.

Over the next decade, IMT-GT evolved with the times. Sustainability, green growth, and long-term planning took centre stage through successive Implementation Blueprints, the establishment of CIMT as the permanent secretariat in 2013, and the adoption of Vision 2036, setting a clear course towards inclusive, innovative, and sustainable development.

Today, with 35 states and provinces and over 30 years of cooperation, IMT-GT continues to adapt and grow. From expanding air connectivity and geopark cooperation to strengthening trade facilitation through the CIQ Framework, IMT-GT remains a living partnership—connecting borders, empowering communities, and shaping the future of subregional cooperation.

IMT-GT Vision 2036

IMT-GT's Vision 2036 sets out a long-term strategy to achieve an Integrated, Innovative, Inclusive, and Sustainable Subregion by 2036. With people at the heart of all development efforts, the vision seeks to promote balanced growth, strengthen regional economic links, and conserve natural resources for the benefit of present and future generations.

The twenty-year vision allows IMT-GT to pursue bold and transformative strategies that address structural challenges, strengthen its industrial base, and enhance competitiveness. As one of Southeast Asia's more advanced subregional groupings, IMT-GT aims to set the pace for future ASEAN Economic Community building process.

Implementation Blueprint

The Vision 2036 roadmap is operationalised through four consecutive five-year Implementation Blueprints (IBs):

IB 2017–2021
IB 2022–2026
IB 2027–2031
IB 2032–2036

Three Guiding Approaches

IMT-GT adopts three mutually reinforcing approaches to drive progress:

Project-centric approach toward greater regional integration.
Project-specific and location-specific regulatory reforms (joint debottlenecking effort).
Spatial approach to regional development.

Institutional Mechanism

IMT-GT's institutional framework brings together leaders, ministers, senior officials, and key stakeholders to ensure the effective implementation of subregional cooperation programmes. Each institutional body plays a distinct yet complementary role in guiding IMT-GT towards its Vision 2036.

Leaders’ Summit

It provides strategic policy direction, fosters consensus on key economic and social development priorities, and guides subregional cooperation and integration among member countries.

Ministerial Meeting

It provides overall guidance on IMT-GT's strategic blueprints. It sets policy directions, addresses emerging challenges, and serves as a platform for ministers to exchange views and strengthen cross-sectoral coordination. The MM translates the vision of the Leaders’ Summit into actionable strategies, ensuring coherence across national policies.

Chief Ministers’ and Governors’ Forum

The forum bridges national and local priorities by aligning subregional initiatives with provincial and state-level development plans. It raises awareness of IMT-GT opportunities and facilitates bottom-up projects that deliver direct benefits to communities.

Senior Officials’ Meeting (SOM)

The SOM plays a pivotal role in translating ministerial guidance into operational plans. It also oversees the effectiveness of measures and strategies, fosters cross-sectoral collaboration to address emerging challenges, and encourages shared responsibilities across IMT-GT bodies.

National Secretariats

Each Member Country maintains a National Secretariat (NS) to coordinate and monitor IMT-GT initiatives at the national level. Serving as the national focal point, the NS integrates IMT-GT programmes into national development agendas and ensures adequate policy and resource support from national government.

Centre For IMT-GT Subregional Cooperation (CIMT)

CIMT serves as the central secretariat for the IMT-GT framework. Its role is to initiate, advise, coordinate, facilitate, implement, monitor, and evaluate IMT-GT programmes, projects, and activities, ensuring they are effectively delivered and aligned with the subregion's strategic priorities. CIMT is based in Putrajaya, Malaysia.

Joint Business Council (JBC)

JBC represents the private sector within IMT-GT, promoting trade and investment while channelling business perspectives into policy discussions. It plays a vital role in fostering entrepreneurship, enhancing competitiveness, and building networks that connect businesses across borders, thereby driving inclusive economic growth in the subregion.

University Network (UNINET)

UNINET connects higher education institutions across the subregion. Established in 1996, UNINET initially comprised eight universities in the network. To date, 32 public universities are members of UNINET. It promotes research collaboration, academic exchange, and innovation, recognising the critical role of education in driving economic and social progress.

Asian Development Bank (ADB)

ADB has been involved in the IMT-GT initiative since its inception, and has been a Development Partner since 2007. ADB's support to IMT-GT covers a wide range of technical assistance. It has been playing a key role as an adviser on policy and technical matters, a trusted facilitator in fostering partnership, and a mobiliser of funding.

International Partnership

IMT-GT engages in partnerships with sovereign states and international/regional organisations that demonstrate both the interest and capacity to contribute meaningfully to IMT-GT's objectives. The Republic of India has been conferred the status of IMT-GT Development Partner, with the partnership guided by a Plan of Action formalising cooperation between the Indonesia-Malaysia-Thailand Growth Triangle (IMT-GT) and India, endorsed by IMT-GT Senior Officials in 2024.

IMT-GT continuously seeks to forge and formalise partnerships with institutional partners. Strategic collaboration with the ASEAN Secretariat ensures alignment with the ASEAN Vision. In addition, IMT-GT works closely with other institutional partners, including United Nations specialised agencies, the International Council for Local Environmental Initiatives (ICLEI), United Cities and Local Governments Asia-Pacific (UCLG ASPAC) as well as other like-minded national and international organisations and non-governmental organisations (NGOs).
