Many people today ask an important question: Why do Cambodia and Thailand continue to face border disputes more than a century after the borders were supposedly defined?. To understand the issue clearly, we must look back in history, to the French colonial era in Indochina.. The Beginning of the Problem In the late 1800s and early 1900s, Cambodia was under French protection as part of French Indochina, while Siam — now modern Thailand — remained
an independent kingdom.. At that time, the borders between Cambodia and Siam were not fully clear, especially in mountainous areas near ancient Khmer temples along the Dângrêk mountain range.. To avoid conflict, France and Siam signed border treaties in 1904 and 1907 to officially define the frontier.. The agreements stated that parts of the border should follow the “watershed line”, meaning the natural ridge of the mountains where rainwater flows in different directions.. However, after
the treaties were signed, French surveyors and cartographers produced official maps showing the border line in more detail.. These French colonial maps later became the centre of controversy.. The French Colonial Maps One of the most important maps was created around 1907.. These maps were prepared by French surveyors and became known internationally as the “Annex I Map”.. On these maps, important ancient Khmer temples, including Preah Vihear Temple, appeared on the Cambodian side of
the border.. Cambodia continues to rely heavily on these French colonial maps as historical and legal evidence because: – they were created during official treaty implementation; – Siam accepted and used them for many years; and – they were later recognised by the International Court of Justice (ICJ).. Cambodia therefore argues that these maps form part of the legitimate historical border settlement.. Thailand’s Modern Maps and the Cold War Era Thailand, however, later developed and
different maps.. During the Cold War era — particularly from the 1950s through the 1970s — Thailand received significant military and technical assistance from the US and Western allies as part of anti-communist regional security cooperation in Southeast Asia.. Advanced aerial photography, military surveys, geodetic systems and topographic mapping technologies were introduced during this period.. As a result, Thailand later produced and relied on modern military-based maps, including highly detailed 1:50,000 topographic maps developed during
the Cold War years.. Thai authorities have argued that these later maps are geographically more accurate because they were based on modern aerial and military surveying technology.. Thailand’s position is that: – the original 1904 treaty should strictly follow the watershed line, – and some French-drawn borders did not perfectly match the natural geography of the mountain range.. However, Cambodia argues that these newer military-era maps were created decades later and were never part of
the original internationally recognised agreements between France and Siam.. This created an inconclusive situation and continuing confusion because: – Cambodia relies mainly on the French treaty maps accepted internationally, – while Thailand relies more heavily on later military and watershed interpretations developed during the Cold War period.. As a result, both sides continue to interpret the border differently.. Why the Issue Became So Serious For many decades, Siam did not formally protest the French maps..
This later became extremely important in international law.. In 1962, the International Court of Justice ruled that the Preah Vihear Temple belonged to Cambodia because the Court determined that Thailand had effectively accepted the French maps through years of non-objection and official usage.. The Court focused heavily on legal acceptance and historical conduct, not just on geographical interpretation.. However, disputes over nearby surrounding areas continued because some sections of the border were never completely demarcated
on the ground.. A Call for Historical Clarity Because many questions still remain sensitive and politically disputed, greater historical transparency is important for both countries and for future generations.. For this reason, many Cambodians hope that France will continue providing archival records, historical documents, and original colonial-era maps created during the French Indochina period.. Such historical materials may help scholars, legal experts and the public of both neighbouring kingdoms better understand how the borders were
originally surveyed and interpreted during that era.. Access to complete historical archives may contribute to greater clarity, reduced misunderstanding, peaceful dialogue and long-term regional stability.. A Lesson From History The Cambodia–Thailand border issue reminds us that many modern conflicts around the world were shaped during the colonial era, when borders were often drawn by foreign powers without fully considering future consequences.. Understanding the historical roots of the issue is important not to create hostility, but
to encourage peaceful dialogue, mutual understanding, and respect for international law between neighbouring nations.. Tesh Chanthorn is a Cambodian citizen who longs for peace.. The views and opinions expressed are his own.
