Cambodia's ambitions to become a major connectivity hub in the Greater Mekong Subregion have faced significant challenges following a brief but intense armed conflict with Thailand in 2025. Until May 2025, the border between Cambodia and Thailand served as a crucial entry point for Cambodian goods into the global economy, leveraging Thailand's port infrastructure and established maritime networks.

The border closures resulting from the conflict sent major shock waves through Cambodia's economy, raising questions about the country's economic resilience. Analysts have pointed to Cambodia's reliance on Thai companies and exports in strategic sectors such as oil and energy, as well as the heavy use of Thai roads and ports, as factors that could undermine its short-term economic prospects.

For Cambodia's connectivity plans, the border conflict initially appeared to signal an end. However, Phnom Penh had already been pursuing investments in transport logistics as a political and diplomatic priority for at least two decades, aiming to strengthen its position amid the complex interplay of economics, trade necessities, and geopolitics in Southeast Asia.

The situation highlights the challenges Cambodia faces in balancing its aspirations to reduce dependencies while maintaining regional connections.
