Bangkok: The dispute in the area of Chong Bok, Nam Yuen District, Ubon Ratchathani Province, saw a notable development when Cambodia decided to withdraw its forces following a minor clash with Thai soldiers. This decision marked a shift towards 'modern security', where economic pressure, rather than military confrontation, became the deciding factor. Thailand employed 'border restriction measures' to control the movement of people, goods, and logistics systems, particularly at the strategically vital Aranyaprathet Checkpoint, a hub of Thai-Cambodian border trade.
According to Thai News Agency, Thailand's strategy involved 'peaceful economic pressure' alongside negotiations, with measures such as prohibiting Thais from gambling in Poipet-Cambodia's main income source-limiting checkpoint operating hours, and tightening control on large goods transportation, especially those at risk of being illegal. Thailand has indicated its readiness to intensify these measures if border tensions persist, which puts pressure on Cambodia's economy, heavily reliant on cross-border trade.
Thailand's economic leverage is underscored by trade data. The Department of Foreign Trade reported that Thai-Cambodian border trade amounted to 64,612 million baht in the first four months of 2025, a 12.3% increase from the previous year, with Thailand enjoying a trade surplus of 35,838 million baht. Key Thai exports, including beverages, milk, sugar, automotive parts, and agricultural machinery, are crucial to Cambodian public consumption and basic industries.
The strategic significance of border checkpoints is highlighted by the Department of International Trade, Ministry of Commerce, which states that Thailand has 18 border crossings with Cambodia. The Aranyaprathet checkpoint alone contributes to 63.4% of border trade value, and when combined with Khlong Yai and Ban Pakkat checkpoints, it comprises over 95% of the total trade value. Restricting or closing these checkpoints would severely impact Cambodia's trade and logistics systems.
The repercussions for Cambodia are manifold: shortages in essential goods like milk, sugar, and beverages, increased logistics costs due to route diversions, disruptions in agriculture and automotive industries, and loss of revenue in casino cities such as Poipet. Samdech Hun Sen, President of the Cambodian Senate, emphasized this dynamic, warning that continued restrictions could hinder Thai access to the Cambodian market, affecting Thai farmers.
Cambodia serves as both an export market and a raw material supplier for Thailand, particularly in cassava, scrap metal, and electronics industry components. Thus, border restrictions could also disrupt Thailand's industrial chain.
The Ministry of Commerce's impact assessment divides the effects into three timelines: short-term (0-3 months) market and logistics disruptions, medium-term (3-12 months) rising production costs and adaptation needs for exporters, and long-term (1 year or more) potential investor confidence loss and strategic opportunity risks for Thailand.
Thailand's use of economic power as a pressure tool-described as Soft Security-demonstrates that military force is no longer the sole determinant of power dynamics. Cambodia's decision to withdraw without escalating conflict reflects the profound strategic implications of economic moves. As the lines between 'security' and 'economy' blur, border crossings have become a measure of inter-state pressure and a pivotal point in power relations. In the Chong Bok confrontation, the economy emerged as a formidable strategy, proving that silent pressure can significantly alter the geopolitical landscape.
