As a centre of trade and economic hubs in mainland Southeast Asia, Thailand persistently keeps on maintaining a strategic approach to maintain its economic growth and regional influence. This is evident through its ambitious Land Bridge Initiative, a project that connects the South Economic Corridor (SEC) provinces and links the Andaman Sea to the Gulf of Thailand. The project plans to further execute construction and revitalisation of infrastructure such as highway roads and ports to advance geographical mobility for all stakeholders, domestically or internationally; providing a mutual economic framework once it operates in 2030. However, this project will significantly impact the Southeast Asian geopolitical realm once it operates as it changes the conventional trade route within the region.
Background
The Land Bridge Initiative is not a new project the Thai Government starts. Instead, it is a modern conceptualisation of the Kra Canal in the 1930s — a canal construction plan that cuts the Southern part of Thailand to connect its eastern and western oceans, as a quicker alternative trade route to the Malacca Strait. The canal has never become successful due to the large construction costs and weak economic rationale. However, as modernisation takes place and the nation oversees a stable growth over the years, the Government sought an opportunity to execute these initial plans through infrastructure advancement. One of which is through the Land Bridge Project that plans to build deep-sea ports located in the Andaman Sea and the Gulf of Thailand, connected by approximately 90 kilometer highway and railway.
In 2021, The Land Bridge Project was revived and promoted by the Thai Government under Prime Minister Prayut Chan-O-Cha. This movement is welcomed, nevertheless it also receives lots of criticism and feedback from the public as it lacks feasibility. However, the Thai Government recognises the significance of public engagement for the success of this project, which includes securing the safeguarding and wellbeing of people in the SEC provinces, not solely in infrastructure. The Thai Office of Transport and Traffic Policy Planning (OTP) attempts to reveal its commitment through specialised geographical analysis, in addition to holding public hearings and official seminars attended by stakeholders in Bangkok and Surat Thani. The outcome of the aforementioned meetings has then been brought forward as the foundation of the South Economic Corridor (SEC) Bill, as a guide to the construction and future development of the 1 Trillion Baht (29 Billion USD) Project. According to the current Deputy Prime Minister, Ms Suriya, the Bill is expected to be approved and implemented this year — signalling a fast-paced and committed move towards the ambitious project. On the international level, Thailand has also promoted the Landbridge project to other countries. A couple of foreign state visitations held by Thailand have also involved a discussion on the future of this project, as it seeks for economic collaboration, particularly on investments. Reportedly, China and Middle Eastern countries were interested in partnerships, alongside with other foreign investors. Despite this, Thailand minimises the possibility of China’s domination in the project, welcoming more opportunities from other foreign nations.
What It Means For Thailand's Economy
As the megaproject has been formally assembled with support from local and international economic actors,
Thailand will potentially experience a rise in its economic growth. The vision of connecting Southeast Southwest Thailand has been an ideal route to boost trade mobility domestically and internationally. The Landbridge Project would shift the ordinary trade route passing through the Malacca strait — which tends to be time-consuming and costly. Consequently, this would alternate the preference of containerisation through the Thai route that potentially may bring about new economic opportunities and activity within the Southern Thai provinces. As this proceeds, this will contribute to a positive economic growth and development. An equalised development within the Southern part of Thailand would also then keep up with the ones on the Central/Upper part of Thailand, ensuring a balance in living standards and economic progress domestically.
Several countries’ interests on the project have also supported optimism for Thailand’s economy. As companies from foreign nations willingly invest in this ambitious project, it would mean more effectiveness for the project execution. The rise in Foreign Direct Investments (FDI) here was again due to the strategic project providing a potential for high returns. This provides a chance for high growth as investments and effectiveness rises.
In a larger context, it is evident that the project would bring about benefit and progression to Thailand’s
economy. Nonetheless, there are concerns on environmental costs the local people will need to face and the
possible impact on their wellbeing. As the crossing bridge passes through houses and lands throughout provinces, it is definite that environmental damages would occur. It is reported that individuals within the Southern province such as Ranong, have been advocating for the Government to conduct sustainable projects that possess lesser negative effects. This has encouraged the Thai government to balance construction and local environment preservation, which would bring about a sustainable economic growth once came into work.
A Change To Southeast Asian Geopolitics?
It is inevitable that the project could significantly reshape Southeast Asia's geopolitical and economic dynamics. By offering a strategic alternative to the ideal Strait of Malacca, the project challenges the maritime and port dominance of Singapore and Malaysia and may shift the region’s logistics and trade routes. This move could elevate Thailand’s status as a major transport hub, attracting infrastructure investments and increasing its geopolitical leverage. As China has shown its interests as the project is on the same mission to the Chinese Belt & Road Initiative, this may provoke counterbalancing efforts from the U.S., Japan, and India. This project may move the ASEAN stance on Indo-Pacific and abandon ASEAN’s centrality and attempts on minimising Chinese influence. In conditions where Thailand did not align to these values, it may contribute to a shift in ASEAN’s solidarity when it comes to its stable and neutral stance between China-Indo-Pacific relations.
The landbridge could also rebalance economic power within ASEAN, redistributing growth from established maritime centers to southern Thailand. While this promises economic benefits, it raises risks of environmental disruption and social unrest, especially in areas with histories of political tension. If local concerns are not addressed, instability could undermine the project and invite broader regional complications. Moreover, the landbridge may force Thailand to rethink its traditionally neutral stance, as major powers fight for influence over this critical corridor. As a result, the project not only shifts trade routes but also introduces new layers of strategic competition in Southeast Asia, which potentially could restrain relations between Singapore/Malaysia with Thailand if one significantly threatens the other.
Conclusion
The Thailand Landbridge Project has the potential to boost national economic growth and reshape Southeast
Asia’s trade routes and geopolitical dynamics. However, it also brings challenges, including environmental
concerns, local resistance, and regional tensions.
To ensure its success, Thailand should prioritise sustainable development, transparent public engagement, and environmental protection. It must also diversify foreign partnerships to avoid overdependence on any single country and work closely with ASEAN to maintain regional unity and stability.
