For foreign investors, the two markets present distinct opportunity profiles within the regional LNG sector. Malaysia offers investment opportunities tied to established export infrastructure, offshore gas production, and LNG trading networks. In contrast, Indonesia’s opportunity profile is increasingly driven by upstream gas discoveries, large-scale LNG developments, and expanding domestic demand for natural gas.

Global LNG supply expansion and Asia’s growing demand

Malaysia and Indonesia operate in a global LNG market experiencing rapid supply expansion alongside sustained demand from Asian importers.

The United States shipped roughly 91 million tonnes of LNG in 2024, making it the world’s largest exporter. Qatar exports more than 80 million tonnes annually, while Australia maintains an export capacity of approximately 80 million tonnes per year.

Despite expanding supply, Asia remains the dominant center of LNG demand. The region accounts for roughly 70 percent of global LNG imports, driven by electricity generation, industrial consumption, and long-term energy security policies.

China imported approximately 68 million tonnes of LNG in 2025, while Japan imported around 67 million tonnes and South Korea approximately 47 million tonnes, making them the world’s largest LNG buyers.

Malaysia and Indonesia benefit directly from this demand structure. LNG shipments from Southeast Asia can reach Northeast Asian markets within three to six days, compared with 20–30 days for cargoes departing the US Gulf Coast, giving regional exporters a transportation advantage in supplying Asian buyers.

Malaysia exports approximately 26–27 million tonnes of LNG annually, while Indonesia exports approximately 15–16 million tonnes, with shipments from the Tangguh and Bontang facilities primarily destined for Japan, China, and South Korea.

Singapore also plays a growing role in regional LNG trade as a financial and trading hub where energy companies manage LNG portfolios and coordinate spot cargo trading across Asia.

Malaysia’s LNG export system and upstream gas supply base

Malaysia’s natural gas resource base

Substantial offshore natural gas resources support Malaysia’s LNG export industry. The country holds approximately 2.6 trillion cubic meters of proven natural gas reserves, with most resources located offshore in Sarawak and Sabah.

Annual natural gas production reaches roughly 70–75 billion cubic meters, supplying both domestic consumption and LNG exports.

Upstream gas developments supporting Malaysia’s LNG supply

Several offshore developments are expanding Malaysia’s gas production capacity.

The Kasawari gas field, operated by Petronas offshore Sarawak, is expected to produce approximately 900 million cubic feet of gas per day once fully operational.

Another major development is the Rosmari–Marjoram gas project, operated by Shell. The project is expected to produce roughly 800 million cubic feet of gas per day, with production expected around 2026.

These projects help sustain Malaysia’s LNG feedgas supply as existing fields mature.

LNG infrastructure anchored by the Bintulu export complex

Malaysia’s LNG industry is centered on the liquefaction facilities at Bintulu operated by Petronas.

The complex operates nine liquefaction trains with a total capacity of approximately 29.3 million tonnes per year, making it one of the largest LNG export hubs in Asia.

Malaysia has also developed a significant LNG trading presence. Petronas manages a global LNG portfolio supplying markets across Asia and Europe. At the same time, nearby Singapore has emerged as a regional LNG trading hub where companies manage LNG cargo portfolios and short-term market transactions.

Indonesia’s LNG export system and future growth pipeline

Indonesia’s LNG export system is anchored by major liquefaction facilities located at Bontang and Tangguh.

Indonesia exported roughly 15–16 million tonnes of LNG annually, supplying long-term buyers across Northeast Asia, including Japan, China, and South Korea.

The country holds approximately 2.8 trillion cubic meters of proven natural gas reserves, providing a strong upstream resource base capable of supporting future LNG production.

New upstream developments and major liquefaction projects increasingly shape Indonesia’s LNG export outlook.

The Tangguh Train 3 expansion added approximately 3.8 million tonnes per year of LNG capacity and required an investment of roughly US$8 billion, strengthening Indonesia’s export capability.

Indonesia’s next major LNG development is the Abadi LNG project in the Masela Block, led by INPEX in partnership with Pertamina. The project is expected to produce approximately 9.5 million tonnes of LNG annually, with total investment estimated at US$19–20 billion.

Recent discoveries in Indonesia’s Andaman Basin, including the Geng North gas field discovered by Eni, have also highlighted the country’s long-term upstream potential. Large discoveries in this frontier basin could support future LNG developments and strengthen Indonesia’s position as a regional gas supplier.

LNG Export Profiles of Malaysia and Indonesia

Foreign investment frameworks in Malaysia and Indonesia’s LNG sector

Foreign participation plays an important role in LNG development in both countries.

In Malaysia, upstream oil and gas resources are administered by Petronas under the Petroleum Development Act. International companies typically participate in production-sharing contracts or joint ventures with Petronas.

Indonesia permits foreign participation through production-sharing contracts administered by the upstream regulator, SKK Migas. Major international companies already play key roles in the country’s LNG sector, including BP at Tangguh and INPEX at the Abadi LNG project.

Investment opportunities across the LNG value chain

Malaysia and Indonesia offer different entry points for foreign investors across the LNG industry. Malaysia’s LNG sector is anchored by mature export infrastructure and long-established supply relationships with Northeast Asian buyers, while Indonesia’s opportunity profile is increasingly shaped by upstream gas discoveries, large-scale LNG developments, and expanding domestic demand for natural gas.

Major LNG Projects in Malaysia and Indonesia

Malaysia’s established LNG infrastructure and Indonesia’s expanding gas discoveries position the two countries at the center of Southeast Asia’s evolving LNG export industry, says Amanda Lam, Consultant, International Business Advisory, Dezan Shira & Associates.

Malaysia

Malaysia’s LNG investment opportunities are concentrated around existing export infrastructure and offshore gas supply networks supporting the Bintulu LNG complex, one of the largest LNG production hubs in Asia, with nine liquefaction trains and a total capacity of approximately 29.3 million tonnes per year.
