THAILAND REVIVES 365 KM SOUTHERN COASTAL HIGHWAY PROJECT
The Government of Thailand is reviving plans to construct a 365 km extension of the Thailand Riviera Coast Road, expanding the country’s coastal highway network to support tourism, regional connectivity and economic development in southern Thailand.
The proposed extension would continue the existing route from Chumphon to Surat Thani, Nakhon Si Thammarat and Songkhla. A feasibility study for the project is scheduled to be prepared in 2027 for the Ministry of Transport.
The original project, also known as the Southern Coastal Road, was approved in 2006, with approx. 515 km of highway constructed between Phetchaburi and Chumphon at a cost of around USD 978 Mn. The revived proposal includes three additional sections of 150 km, 200 km and 85 km, increasing the total length of the Thailand Riviera Coast Road to approx. 880 km.
The extended highway is expected to improve access to key coastal destinations, strengthen regional transport links and boost tourism across southern Thailand. The Ministry of Transport is currently evaluating the construction costs for the remaining sections of the route.
WORLD BANK APPROVES USD 200 MN PROJECT TO ACCELERATE CLEAN ENERGY DEPLOYMENT IN THAILAND
The World Bank has approved a USD 200 Mn project to support the deployment of clean energy across Thailand’s public sector through an innovative financing platform that combines private investment with carbon market mechanisms. The Low Carbon Cities and Carbon Market Development Project (LCC) is designed to enable public organisations to implement renewable energy and energy efficiency projects without requiring large upfront capital investments. The private energy service companies (ESCOs) will finance and implement the projects, while government agencies will repay the investment through long-term service agreements.
The programme will support the installation of rooftop solar systems and energy efficiency upgrades across public buildings, schools, healthcare facilities, district offices, industrial estates and streetlighting. The World Bank estimates that the project will add up to 180 MW of renewable energy capacity and deliver approx. 448 GWh of annual electricity savings. The initiative is also expected to create at least 1,800 job-years during implementation in areas such as renewable energy installation, operations and maintenance, energy services and digital carbon monitoring. Financing for eligible ESCOs will be provided by the Export-Import Bank of Thailand, while Krungthai Bank will aggregate carbon credits generated by the projects and connect them to carbon markets to create an additional revenue stream for future investments.
The project has been developed in partnership with Thailand’s Public Debt Management Office, the Department of Climate Change and Environment, the Bank of Thailand, the Securities and Exchange Commission, the Stock Exchange of Thailand, the Thailand Greenhouse Gas Management Organisation and other government agencies. The initiative is expected to lower public-sector energy costs, attract private investment, strengthen energy security and establish a scalable financing framework to support Thailand’s carbon neutrality and net-zero emissions goals while advancing sustainable economic growth.
THAILAND REVIEWS USD 717.7 MN EV INCENTIVE PROGRAMME TO REPLACE 80,000 COMMERCIAL VEHICLES
The Thai government is reviewing a THB 24 Bn (USD 717.7 Mn) incentive programme to replace up to 80,000 ageing commercial transport vehicles with electric vehicles (EVs) as part of its energy transition strategy. The proposal, submitted by the Ministry of Transport to a government committee chaired by the Ministry of Finance, initially targets taxis, motorcycle taxis, tuk-tuks, buses and trucks, although the government is also considering extending the incentives to all vehicle categories. The support package could include subsidies, low-interest loans and tax incentives for eligible vehicles meeting specified age limits.
The programme gained momentum after Thailand’s Constitutional Court upheld the government’s THB 400 Bn (USD 11.0 Bn) emergency borrowing plan, enabling additional spending on energy transition initiatives. For taxi operators replacing vehicles reaching the 10-year age limit in 2027, the government is considering financing support that would reduce daily EV loan repayments to THB 500 (USD 13.8) from around THB 700 (USD 19.3) over a five-year period. Similar support is being evaluated for minibuses, vans, buses, tuk-tuks, heavy commercial vehicles and pickup trucks, including incentives for EVs and B20 biodiesel-compatible models.
The proposed scheme aims to accelerate transport electrification while supporting Thailand’s automotive industry, which has faced declining domestic demand. In 2025, 621,166 vehicles were sold domestically, including 120,301 passenger EVs, while approx 1.7 million motorcycles were sold during the year. Industry groups have called for any new incentives to prioritise locally manufactured EVs using predominantly domestic components to strengthen local production, employment and supply chains. Thailand has attracted more than USD 4 Bn in EV investments, including from Chinese manufacturers BYD and Great Wall Motor, although the country’s current EV incentive programme is due to expire in 2027.
THAILAND SCRAPS USD 30 BN LAND BRIDGE PROJECT OVER FINANCIAL RISKS
Thailand is officially preparing to cancel its proposed USD 30 Bn land bridge mega-project following a recent comprehensive government review. The ambitious initiative originally aimed to construct a 100-kilometre transport corridor connecting the Gulf of Thailand with the Andaman Sea. This route was designed to cut shipping times between the Indian and Pacific Oceans by bypassing the congested Malacca Strait. The Strait of Malacca is a critical global maritime chokepoint that currently facilitates nearly 40% of all international trade. However, new assessments have fundamentally shifted the government's perspective on the project's overall feasibility and strategic value.
The primary reasons for scrapping the initiative center on severe financial unviability and significant environmental risks. Projected financial returns for the transport corridor unexpectedly plummeted to less than 5%, while estimated cargo volumes dropped by 16% compared to initial forecasts. Furthermore, there is very little commercial interest remaining, as most major global shipping lines have already committed investments to rival regional projects. Ecologically, the construction threatened to inflict severe damage upon highly sensitive areas, including vital wetlands, biosphere reserves, and established marine tourism sites. Consequently, a designated committee has strongly recommended the immediate termination of the proposed corridor to avoid inevitable financial losses.
Instead of the massive land bridge, the government will now shift to a more sustainable and cost-effective logistical strategy. The revised plan focuses on significantly upgrading the existing Ranong Port infrastructure to better handle modern maritime demands. Additionally, a new rail connection will be built to link the Andaman coast directly to the country's pre-existing national railway network. This alternative approach aims to improve domestic freight transport without the exorbitant costs of the original mega-project. Officials noted that no financial losses were incurred regarding the canceled land bridge, as land acquisition and construction had not yet commenced.
THAILAND AIMS TO COMPLETE THE FIRST SECTION OF ITS HSR LINK TO CHINA BY 2030
Thailand has established a new target of 2030 to complete the initial 250 Km phase of its high-speed railway, which will connect Bangkok to Nakhon Ratchasima. This segment is designed to accommodate train speeds of up to 250 Km per hour and represents a major step in regional connectivity. The updated timeline was established following recent diplomatic discussions in China, where officials from both countries agreed to accelerate their joint infrastructure and transportation initiatives.
Following this initial phase, the government plans to construct a second section extending the line to Nong Khai on the Laotian border. This expansion will eventually link up with existing Laotian railway networks, creating a continuous route to Kunming in southwestern China. Ultimately, this Thai initiative serves as a crucial component of a massive 3,900-kilometer regional railway corridor. The overarching long-term vision is to connect southern China with multiple Southeast Asian nations, eventually stretching all the way down to Singapore.
The ambitious infrastructure project originally began in 2017 but has suffered numerous setbacks, including funding disputes, land acquisition issues, and tragic construction accidents. These ongoing challenges forced the government to push the initial completion deadline back from its original target of 2028 to the newly announced 2030 timeframe. Despite these delays, completing this railway remains a significant priority for advancing regional passenger transport and international trade. Once fully operational, the expanded network will solidify the country's position as a central logistics hub for the entire region.

Oman and Thailand have signed a Memorandum of Understanding to significantly boost bilateral cooperation and joint investments within the energy sector. This strategic agreement focuses on exchanging advanced technologies, sharing critical policies, and fostering a more robust energy ecosystem between the two nations. The core initiative stems from a mutual commitment to deepen economic ties and create new operational opportunities for their respective energy companies.
Energy ministers from both countries formalized the pact, which establishes the Oman-Thailand Energy Policy Dialogue to seamlessly unite private sector representatives. This new institutional platform is designed to identify joint projects, streamline bilateral consultations, and develop long-term cooperation programs. Additionally, the agreement heavily emphasizes comprehensive workforce development through shared training, expert visits, and collaborative research initiatives.
