Why Siamese Commissioners Neither Approved Nor Objected to the 1907 French Map Placing Preah Vihear on Cambodia's Side

Introduction

The controversy surrounding the Temple of Preah Vihear, a majestic Khmer temple perched atop a cliff on the border between Thailand and Cambodia, has been a long-standing source of tension between the two Southeast Asian nations. A key element in this dispute is the 1907 French map, which placed the temple within Cambodian territory. This map, drawn by French cartographers acting on behalf of the Siamese (Thai) government at the time, has been a subject of intense debate, particularly regarding the Siamese commissioners' apparent silence on its accuracy. This article delves into the complex historical context surrounding the 1907 map, exploring the reasons why the Siamese members of the Mixed Commission neither explicitly approved nor objected to it, and shedding light on the intricate geopolitical dynamics that shaped the Preah Vihear dispute.

The dispute over Preah Vihear is not merely a territorial squabble; it is deeply intertwined with issues of national identity, sovereignty, and historical legacy. Understanding the historical context, including the treaties, maps, and the actions (or inactions) of key figures, is crucial to grasping the complexities of the conflict. The silence of the Siamese commissioners regarding the 1907 map is a pivotal point in this history, raising questions about their understanding of the map's implications, the political pressures they faced, and the broader context of French colonial influence in the region. This article aims to provide a comprehensive analysis of these factors, drawing upon historical sources and scholarly interpretations to offer a nuanced perspective on this critical episode in Thai-Cambodian relations. The exploration of the 1907 French map and the Siamese commissioners' response will provide a basis for understanding the ongoing contentions surrounding Preah Vihear and the quest for a lasting resolution.

The 1904 Franco-Siamese Treaty and the Mixed Commission

In order to fully comprehend the silence of the Siamese commissioners, it is essential to first understand the historical backdrop against which the 1907 map was produced. The 1904 Franco-Siamese Treaty was a pivotal agreement that aimed to delineate the border between Siam (now Thailand) and French Indochina (which included Cambodia, Laos, and Vietnam). This treaty emerged from a period of intense colonial rivalry in Southeast Asia, where France sought to expand its influence at the expense of Siam. The treaty stipulated that the border in the Preah Vihear region would follow the watershed line, a geographical feature that naturally divides drainage basins. This principle seemed straightforward, but its practical application proved to be highly contentious.

To implement the 1904 treaty, a Mixed Commission was established, comprising French and Siamese representatives. This commission was tasked with surveying the border and producing a map that accurately reflected the treaty's provisions. The French, with their superior cartographic expertise and colonial ambitions, played a dominant role in this process. The Siamese commissioners, on the other hand, were operating in a context of political pressure and limited resources. Their ability to effectively challenge the French interpretations and mapping was constrained. The 1904 treaty and the establishment of the Mixed Commission were, therefore, critical precursors to the creation of the 1907 map and the subsequent dispute. The dynamics within the Mixed Commission, the relative power of the French and Siamese representatives, and the specific instructions given to the commissioners all played a role in shaping the outcome. This background understanding is essential to analyze the commissioners’ response to the contentious 1907 map and the implications of their actions or inactions.

The 1907 French Map: A Point of Contention

The 1907 French map is at the heart of the Preah Vihear dispute. This map, produced by French cartographers, placed the entire Preah Vihear temple complex on the Cambodian side of the border. This delineation deviated from a strict interpretation of the watershed line, which some argued would have placed at least a portion of the temple on Siamese territory. The map was presented to the Siamese government, and copies were distributed. It is the Siamese commissioners' response to this map, or rather the lack thereof, that has fueled much of the controversy.

The map's significance stems from its legal implications. Cambodia has consistently argued that the 1907 map represents an authoritative demarcation of the border, accepted by Siam at the time. Thailand, however, has contested the map's accuracy and the validity of Siam's acceptance, arguing that the Siamese commissioners did not have the authority to cede territory and that the map was not properly scrutinized. The map's depiction of Preah Vihear within Cambodian territory became a crucial piece of evidence in the International Court of Justice (ICJ) case that ultimately awarded the temple to Cambodia in 1962. The ICJ placed significant weight on the map and the Siamese government's initial lack of protest, interpreting this as tacit acceptance. Therefore, the 1907 map is not simply a historical artifact; it is a legal document with profound consequences for the territorial integrity and sovereignty of both Thailand and Cambodia. The debate over its interpretation and validity continues to shape relations between the two countries.

Why No Objection? Exploring the Silence of the Siamese Commissioners

The central question in the Preah Vihear dispute is: Why didn't the Siamese commissioners object to the 1907 map if they believed it misrepresented the border? There are several possible explanations, ranging from genuine acceptance of the map's accuracy to political constraints and a lack of understanding of the long-term implications. One argument is that the Siamese commissioners, lacking the technical expertise of their French counterparts, may have simply accepted the French interpretation of the watershed line and the map's depiction. The French had significantly more resources and experience in cartography, and the Siamese commissioners may have deferred to their judgment.

Another explanation centers on the political context of the time. Siam was under considerable pressure from France, which was actively expanding its colonial empire in Southeast Asia. Objecting to the map could have provoked a more assertive stance from the French, potentially leading to further territorial concessions or even military intervention. The Siamese government may have calculated that accepting the map, even if it meant ceding some territory, was the lesser of two evils. Furthermore, the Siamese commissioners may not have fully grasped the long-term implications of the map. The temple itself may not have been seen as particularly valuable at the time, and the focus may have been on securing the broader border demarcation. It's also possible that internal communication and coordination within the Siamese government were lacking, and the commissioners did not receive clear instructions or support in challenging the French. The complex interplay of these factors likely contributed to the Siamese commissioners' silence, making it a pivotal and controversial moment in the history of the Preah Vihear dispute. Understanding these explanations provides insight into the complexities of the historical context and the political pressures shaping the decisions of the Siamese commissioners.

Factors Contributing to the Siamese Commissioners' Inaction

Several factors likely converged to explain the Siamese commissioners' inaction regarding the 1907 map.

Limited Cartographic Expertise: The Siamese commissioners may have lacked the technical skills and resources to effectively challenge the French cartographers. Cartography was a relatively new science in Siam at the time, and the French had a clear advantage in terms of expertise and technology. This disparity in capabilities could have led the Siamese commissioners to defer to the French interpretation of the border.
Political Pressure from France: Siam was in a vulnerable position vis-à-vis France, which was actively expanding its colonial empire in Indochina. Objecting to the map could have been seen as a risky move that might provoke further French aggression. The Siamese government may have prioritized maintaining peaceful relations with France, even at the cost of some territorial concessions.
Lack of Clear Instructions: The Siamese commissioners may not have received clear instructions from their government on how to handle the border demarcation in the Preah Vihear region. This ambiguity could have led to a cautious approach, where the commissioners were hesitant to take a firm stance without explicit authorization.
Misunderstanding of the Map's Implications: It is possible that the Siamese commissioners did not fully appreciate the long-term implications of the map's depiction of Preah Vihear. The temple itself may not have been seen as a strategically or culturally significant site at the time, and the focus may have been on the overall border demarcation.
Internal Political Dynamics: Internal political divisions within the Siamese government may have also played a role. Different factions may have had different views on how to deal with the French and the border issue, making it difficult to formulate a unified response. These complex factors show the difficult position the Siamese commissioners were in when facing French authority and cartographic expertise. Understanding the map's significance and having clear directives from their government may have seemed secondary in preserving Siam's sovereignty.

The Aftermath and the ICJ Ruling

The Siamese commissioners' silence had profound consequences in the decades that followed. In the 1950s, after Cambodia gained independence from France, the dispute over Preah Vihear resurfaced. Cambodia argued that the 1907 map clearly placed the temple within its territory and that Siam's initial acceptance of the map was legally binding. Thailand, however, contested the map's validity and argued that the border should be determined based on the watershed line, which would have placed at least part of the temple in Thailand.

The dispute ultimately went to the International Court of Justice (ICJ), which issued its landmark ruling in 1962. The ICJ sided with Cambodia, ruling that Thailand was precluded from denying that it had accepted the map as representing the correct frontier. The court placed considerable weight on the Siamese government's failure to object to the map in the years following its publication. This ruling was a major victory for Cambodia and a setback for Thailand, but it did not fully resolve the underlying tensions. In fact, clashes between Thai and Cambodian forces have occurred near the temple in recent years, highlighting the ongoing sensitivity of the issue.

The ICJ's decision in 1962 underscored the lasting impact of the Siamese commissioners' silence. Had they raised objections to the map at the time, the course of history might have been very different. The case demonstrates the importance of clear communication, thorough scrutiny, and assertive action in international boundary disputes. The Preah Vihear case serves as a cautionary tale about the long-term consequences of seemingly minor decisions and the enduring significance of historical maps in shaping territorial claims and international relations. The aftermath of the Siamese commissioners' inaction shows that decisions made in the past can have lasting repercussions on international relations and territorial integrity, emphasizing the importance of understanding the historical context of current disputes.

Conclusion

The story of the 1907 French map and the silence of the Siamese commissioners is a complex and multifaceted one. It involves a confluence of factors, including colonial pressures, cartographic expertise, political calculations, and perhaps a lack of foresight. The Siamese commissioners' failure to object to the map, whether due to genuine acceptance, political constraints, or a misunderstanding of its implications, had far-reaching consequences. It paved the way for the ICJ ruling in 1962, which awarded Preah Vihear to Cambodia, and it continues to shape relations between Thailand and Cambodia today.

The Preah Vihear dispute serves as a valuable case study in the complexities of international boundary disputes and the enduring legacy of colonial-era treaties and maps. It highlights the importance of historical context, the significance of clear communication and assertive action, and the long-term ramifications of decisions made in the face of political pressure. The lesson learned from this historical episode is the importance of understanding the historical context when interpreting treaties and maps in border disputes. Understanding the historical context of this dispute is crucial for fostering a peaceful and mutually beneficial resolution to the Preah Vihear issue and for promoting regional stability in Southeast Asia.
