In 2026, many Southeast Asian countries are simultaneously advancing deepwater terminals, green-fuel bunkering berths, and cross-border land logistics hubs. Combined with the rollout of the ASEAN green shipping corridor framework and a sharp increase in regional local-currency settlement, a new port-and-shipping logistics network is taking shape. The Seacons Asia industry team conducted on-site research in key port zones in Singapore, Vietnam, Cambodia, Malaysia, and Indonesia, integrating four dimensions of data—terminal expansion progress, methanol bunkering support, cross-border multimodal cooperation, and digital port upgrades—to fully unpack the new landscape of integrated ASEAN port logistics development.
1. Core port expansion projects in each country are moving ahead at full speed
1. Singapore Port: Asia's methanol bunkering hub takes shape
In February 2026, Singapore's large green methanol bunkering hub officially began operations. Three dedicated deep-water bunkering berths were fully completed, with a single-vessel bunkering capacity of 12,000 tons and annual green methanol supply capacity of 500,000 tons, fully covering VLCC ocean-going refueling demand. The Maritime and Port Authority of Singapore has issued three methanol bunkering operating licenses and is also accepting LNG bunkering qualification applications, building a diversified low-carbon fuel bunkering center and becoming a key supply port on the Middle East-ASEAN crude route.
2. Vietnam expands its north-south twin hubs and builds large transshipment ports
In the north, Hai Phong's Lach Huyen deepwater port has attracted investment from PSA Group, adding four ultra-large container berths while also planning reserved methanol-bunkering berths to serve China-Vietnam feeder routes and ocean-going tanker calls.
In the south, Ho Chi Minh City's Cai Mep international transshipment port has a total investment of $5 billion. Phase one can berth 24,000 TEU ultra-large container ships, and long-term throughput capacity is set to exceed 16.9 million TEU. Positioned as the southern Southeast Asian container transshipment hub, it also has dedicated hazardous-goods berths to support shipping demand for palm oil and chemicals.
3. Sihanoukville Port Phase II expansion accelerates
Sihanoukville Autonomous Port is moving its deepwater upgrade forward in three phases. Phase II has total investment of $243 million and includes a new 350-meter deep-water container berth with a depth of 14.5 meters, capable of receiving 15,000 TEU-class large vessels. The port area has reserved land for methanol bunkering facilities, which are planned to be installed in 2027, opening a low-carbon sea route across the Indochina Peninsula and reducing Cambodia's foreign-trade transshipment costs.
4. Indonesia-Malaysia cross-border port alliance opens up the Sumatra logistics corridor
Indonesia's Belawan New Container Terminal (BNCT) has signed a strategic cooperation memorandum with Penang Port and Perlis Inland Port to build a sea-rail intermodal corridor between Sumatra and the Malay Peninsula. The route spans 388 kilometers and uses digital systems to enable one-stop customs clearance for cross-border cargo, focusing on shipping Indonesian bulk goods such as palm oil, coffee, and rubber to the Chinese, Thai, and Cambodian markets, activating the logistics vitality of the Indonesia-Malaysia-Thailand Growth Triangle.
5. Thailand's Laem Chabang Phase III expands, upgrading EEC logistics
After Laem Chabang Port Phase III was completed, annual container throughput increased from 11 million TEU to 18 million TEU, with new deep-water berths for ocean shipping and rail yards. Map Ta Phut Industrial Port also expanded its liquid-bulk terminal to handle methanol and chemical storage and transshipment, while a port automation TOS system is helping fully improve Thailand's import-export cold-chain and energy-cargo turnover efficiency.
2. The ASEAN green shipping corridor framework has been launched, with low-carbon port infrastructure in place
In January 2026, the ten ASEAN countries formally signed a regional green shipping corridor framework agreement, setting a target of near-zero emissions on core routes by 2035. Singapore, Port Klang, and Laem Chabang were the first to launch pilot low-carbon routes, with key supporting measures:
- All port zones must uniformly plan reserved berths for methanol and ammonia bunkering, and new terminals must reserve pipelines for low-carbon fuels;
- Unified local implementation standards for IMO Tier III emissions are being coordinated, simplifying low-carbon vessel berthing approval procedures;
- Port handling-fee reductions and subsidies will be provided for methanol dual-fuel ships and electric container tractors, lowering shipowner transition costs.
Compared with LNG-powered support infrastructure, Southeast Asian ports generally prioritize methanol bunkering because it costs less to retrofit and has lower storage and transport barriers, matching the fleet-upgrade needs of regional small and mid-sized shipowners and forming a complete industrial support system with the methanol VLCCs and chemical tankers delivered in 2026.
3. Cross-border multimodal transport + local-currency settlement reduce regional logistics costs
-
Denser sea-rail intermodal networksThe 2026 joint meeting of the China-Malaysia port alliance finalized a digital interconnection plan. Beibu Gulf Port now shares data with Port Klang and Penang Port, cutting transshipment time for sea-rail cargo by 30%. Indonesia, Malaysia, and Thailand have also opened cross-border inland-port land routes so bulk agricultural products no longer need multiple transshipments and can reach end markets directly.
-
ASEAN local-currency transaction (LCT) scale is surgingAs of July 2025, total ASEAN cross-border local-currency transactions reached $14.1 billion, doubling year over year. The 2026 ASEAN Summit is expanding local-currency settlement pilots, with direct clearing in RMB, Indonesian rupiah, Thai baht, and Malaysian ringgit covering maritime trade in crude oil, methanol, palm oil, and other bulk commodities. This avoids dollar intermediated exchange, sharply cuts shipowners' fuel procurement and port-fee FX losses, and lowers cross-border logistics financing costs.
4. Port digitization is rolling out across the board, and smart logistics are becoming mainstream
Ports in Thailand, Cambodia, and Myanmar have all launched unified multi-cargo terminal operating systems (TOS), enabling digital scheduling for containers, liquid chemicals, and bulk cargo. Ports in Singapore and Vietnam have built carbon-tracking platforms that automatically record vessel berth emissions and generate EU CBAM carbon-tax filing documents with one click.
End-to-end digitization connects cargo flows, information flows, and capital flows, shortening cross-border customs clearance times by more than 50% and significantly improving the turnover efficiency of e-commerce, energy, and chemical bulk logistics.
5. Industry outlook
Over the next 2-3 years, ASEAN port investment will concentrate on three areas: deep-water berths, methanol bunkering, and automation equipment. Singapore will continue to consolidate its position as Asia's green bunkering and shipping-finance hub, while ports in Vietnam, Cambodia, and Indonesia will absorb incremental regional trade.
Supported by the three policy dividends of the green shipping corridor, cross-border multimodal transport, and local-currency settlement, ASEAN will form an integrated low-carbon port-and-shipping logistics network. Methanol dual-fuel fleets and port bunkering infrastructure will create a closed loop, reshaping the energy-transport and regional bulk-commodity supply-chain landscape between the Middle East and Southeast Asia.
