The Thai Canal Project as an Alternative to the Strait of Malacca in the Emerging Multipolar Order

This article examines the proposed deep-water canal across the Kra Isthmus as a potential alternative to the Strait of Malacca in the context of shifting global power dynamics. Combining historical analysis with economic assessment and geopolitical evaluation, the study traces the evolution of the project from its seventeenth-century origins to its renewed strategic relevance in the twenty-first century.

The canal has re-emerged in policy debates amid increasing congestion in the Strait of Malacca – through which up to 90,000 vessels transit annually – and growing concerns over the vulnerability of critical maritime chokepoints. From a logistical standpoint, the project promises to shorten maritime routes by approximately 700 miles and reduce transit time by up to three days. For Thailand, it could serve as a catalyst for regional development and a means of enhancing its strategic leverage in Southeast Asia.

At the geopolitical level, the canal is analyzed within the framework of China’s “Malacca dilemma” and the broader transformation of maritime connectivity in the Asia-Pacific region. An alternative route linking the Andaman Sea and the Gulf of Thailand could reduce China’s dependence on the Strait of Malacca and influence regional balances of power, including the positions of Singapore and the United States. The article also considers the potential role of BRICS and the New Development Bank as alternative financing mechanisms.

However, the project faces significant obstacles, including high capital costs (estimated at over $30 billion), environmental risks, domestic political constraints, and external strategic pressures. Although the Kra Canal remains hypothetical, its strategic implications ensure its continued relevance in regional and global debates. The study concludes by assessing possible implications for Russia within emerging multilateral and transport frameworks.
