Why International Law Matters to Cambodia
The award of the 2026 Nobel Peace Prize to Navi Pillay comes at a time when international law and the institutions charged with upholding it, face growing political pressure. Honouring a jurist with the Nobel Prize for Peace, whose career has been closely associated with human rights and international accountability is therefore more than a recognition of individual achievement. It is also an affirmation of the principles on which peaceful relations between states depend.
Yet international institutions have never been insulated from political power. The history of the Nobel Peace Prize, like Cambodia’s own experience of international recognition and accountability, reveals the tensions between universal principles and geopolitical interests.
For Cambodia, these tensions are not merely a matter of international debate. The country has experienced the consequences of international decisions shaped by strategic calculations, as well as the possibilities and limitations of international legal processes. Its history offers a compelling reason to defend international law without idealising the institutions through which it operates.
Recognition, Reputation and Responsibility
The Nobel Peace Prize carries considerable moral authority, but that authority is not beyond question. Its history includes decisions that have raised doubts about the relationship between political achievement and the values the prize is meant to represent.
For Cambodia, the 1973 award to Henry Kissinger remains a particularly stark example. Kissinger, then US National Security Adviser and later Secretary of State, shared the prize with North Vietnamese negotiator Lê Đức Thọ for negotiating a ceasefire in Vietnam. Yet Kissinger had also played a central role in US policy in Indochina, including the secret bombing of Cambodia and Laos. The contradiction was stark: a man associated with the conduct of a devastating war was being honoured for negotiating its end. Lê Đức Thọ refused the prize, arguing that peace had not yet been established. The award provoked controversy, including the resignation of two members of the Nobel Committee.[1]
The lesson is not that diplomacy should go unrecognised, or that political negotiations can only be judged by their eventual outcomes. It is that an achievement cannot always be separated from the wider record of the person being honoured.
Recognition carries a political message: whose suffering is acknowledged, whose responsibility is overlooked, and what, ultimately, is being affirmed in the name of peace?
The later trajectory of Aung San Suu Kyi offers a different but equally troubling illustration. Awarded the Nobel Peace Prize in 1991 for her non-violent struggle for democracy and human rights in Burma, she became an international symbol of resistance to military rule. Her subsequent defence of Myanmar’s military before the International Court of Justice (ICJ), however, profoundly damaged that reputation.
In December 2019, Suu Kyi appeared before the Court as Myanmar’s Agent in proceedings brought by The Gambia, which accused Myanmar of violating the Genocide Convention through its treatment of the Rohingya. Navi Pillay, who would later receive the Nobel Peace Prize, sat in the same proceedings as a judge ad hoc appointed by The Gambia.[2] The two women occupied very different institutional roles: Suu Kyi represented her government’s position, while Pillay served in a judicial capacity.
Their presence in the same courtroom brought into sharp contrast a central question: what happens when political loyalties come into conflict with the principles of human rights and accountability?
The Nobel Peace Prize cannot guarantee that the values it celebrates will guide its recipients’ actions thereafter. Nor can recognition, by itself, establish the moral legitimacy of an individual or an institution. These distinctions matter when considering the role of international institutions more broadly. Their authority depends not simply on the principles they proclaim, but on how consistently those principles are upheld when political interests point in another direction.
Cambodia’s Experience of International Legitimacy
Cambodia’s own history offers a particularly telling perspective on the gap between international recognition and moral legitimacy.
After Vietnamese forces toppled the Khmer Rouge regime in 1979, a new government was established in Phnom Penh. The question of who could legitimately represent Cambodia became entangled in Cold War politics. Many Western countries, China and ASEAN opposed Vietnam’s intervention and did not recognise the People’s Republic of Kampuchea. The dispute concerned not only the Khmer Rouge’s crimes, but also Vietnam’s military presence in Cambodia and the regional balance of power.[3]
In 1982, three factions opposed to the Phnom Penh government formed the Coalition Government of Democratic Kampuchea. It brought together the Khmer Rouge, Prince Norodom Sihanouk’s royalist movement and Son Sann’s Khmer People’s National Liberation Front. The coalition continued to occupy Cambodia’s seat at the United Nations, despite the Khmer Rouge’s responsibility for mass atrocities.
The contradiction was profound. International representation was shaped by strategic opposition to Vietnam’s intervention, even when this meant accepting the credentials of a coalition that included the Khmer Rouge. Sovereignty and self-determination were invoked in ways that reflected competing geopolitical interests, while the suffering of Cambodians under the Khmer Rouge did not determine the international response.
This episode illustrates why international recognition and moral legitimacy cannot be treated as interchangeable. It also demonstrates how principles that are intended to apply universally can be interpreted selectively when powerful states pursue strategic objectives.
The Paris Peace Agreements of October 1991 opened a different chapter. They established the basis for a negotiated political settlement and an internationally supervised transition. The United Nations Transitional Authority in Cambodia (UNTAC) was tasked with overseeing elections, supporting the return of refugees, monitoring human rights and helping establish the conditions for a new political order.[4] The process was neither simple nor without shortcomings, but it demonstrated that international engagement could contribute to a settlement after years of conflict.
The subsequent establishment of the Extraordinary Chambers in the Courts of Cambodia (ECCC) represented another attempt to address the legacy of the Khmer Rouge period through legal accountability.
The ECCC secured convictions of senior Khmer Rouge leaders, including Nuon Chea and Khieu Samphan. At the same time, its record was marked by controversy over the scope of prosecutions, particularly the stalled or terminated investigations in Cases 003 and 004. These proceedings prompted concerns about political interference and judicial independence, including following disagreements within the tribunal and the resignations of international investigating judges.[5]
The ECCC thus demonstrated both the possibilities and the limitations of international justice. It enabled legal proceedings against senior leaders responsible for grave crimes, while exposing the difficulties of pursuing accountability in a politically sensitive environment.
These episodes belong to different historical and legal contexts. Together, however, they reveal a persistent challenge.
International institutions can help advance peace, sovereignty and accountability, but their decisions and effectiveness are not insulated from political power.
The Limits and Necessity of International Law
Criticism of double standards in international justice is justified when powerful states or political interests influence which violations receive attention and which perpetrators face consequences. But inconsistency is not a reason to abandon accountability. It is a reason to demand that legal principles be applied more consistently.
International law is not a single institution, nor does it offer one universal route to justice. The International Court of Justice adjudicates legal disputes between states, while the International Criminal Court prosecutes individuals accused of genocide, war crimes, crimes against humanity and the crime of aggression, within its jurisdiction. Their mandates differ, and neither can by itself guarantee that states or individuals will comply with the law.[6]
International law cannot eliminate political interests, and legal institutions cannot ensure that every violation will be investigated or every judgment enforced. Yet without independent institutions and credible procedures, the powerful have even greater freedom to determine when rules apply and to whom.
For Cambodia, this is not an abstract question. The country’s experience demonstrates both the consequences of international decisions shaped by geopolitical calculations and the value of legal processes that offer alternatives to confrontation.
The dispute over the Temple of Preah Vihear provides a clear example. In 1962, the ICJ ruled that the temple was situated in Cambodian territory. In a further judgment in 2013, the Court clarified that Cambodia’s sovereignty extended over the whole promontory on which the temple stands.[7]
The case did not settle every aspect of the Cambodia–Thailand border, nor did it eliminate tensions between the two countries. But it established a legal position on a contested question of sovereignty. Cambodia was able to take its case before an international court and obtain a binding judgment based on law rather than military or economic strength alone.
That is significant for any smaller country.
International legal mechanisms do not remove unequal power relations, but they can create a framework in which claims must be argued, evidence considered and decisions justified in legal terms.
The current tensions between Cambodia and Thailand underline the continuing importance of peaceful mechanisms for resolving disputes. The maritime-boundary dispute in the Gulf of Thailand is separate from the Preah Vihear case. In 2026, Cambodia initiated conciliation under the United Nations Convention on the Law of the Sea (UNCLOS), and Thailand agreed to participate. According to the Permanent Court of Arbitration’s update of 19 October 2026, the second session of the Conciliation Commission took place from 14 to 18 October, and the parties finalised a set of confidence-building measures.[8]
Conciliation is intended to help the countries find a negotiated solution; unlike adjudication, it does not produce a binding judicial judgment. Its significance lies in creating a structured process for dialogue and agreement, even where the parties’ positions differ.
Neither international courts nor conciliation can guarantee that disputes will be resolved quickly, or that governments will always accept outcomes they dislike. But legal procedures provide rules, a basis for negotiation and a means of addressing competing claims without leaving the outcome to military strength alone.
For Cambodia, that is extremely important.
Why Navi Pillay’s Recognition Matters
Navi Pillay’s career, from defending anti-apartheid activists in South Africa to serving as a judge at the International Criminal Tribunal for Rwanda and as UN High Commissioner for Human Rights, has been closely associated with advancing accountability and the rule of law. At the Rwanda tribunal, her work contributed to jurisprudence recognising that rape and sexual violence could constitute acts of genocide.[9]
Her recognition matters not because it resolves the contradictions of international justice, but because it draws attention to the institutions and principles that her career has helped advance. This is particularly significant at a time when independent judicial mechanisms face political pressure and the application of international law remains contested.
The controversy surrounding international courts and the individuals who serve them raises a wider question: what happens when legal accountability threatens powerful political interests? Threats of sanctions against independent judges and pressure on international judicial institutions illustrate the vulnerability of legal processes when their work challenges those with political or economic power.
Pillay’s recognition is therefore a reminder that the rule of law depends on more than formal institutions. It requires political actors to respect judicial independence, governments to accept legal constraints, and societies to defend the principle that no one should be beyond accountability.
For Cambodia, the message is especially relevant. Its history shows that international recognition can be shaped by strategic interests, and that international justice can be constrained by political considerations and power. But it also shows that international legal processes can establish rights, create avenues for accountability and offer alternatives to confrontation.
Conclusion: The Force of Law
Cambodia’s history reveals the costs of international decisions shaped by geopolitical calculations. It also demonstrates the value of legal processes that allow disputes to be addressed and rights to be asserted without leaving the outcome to military or economic strength alone.
The defence of international law does not require us to idealise international institutions or overlook their shortcomings. It requires us to insist that legal principles be applied consistently, independently and without deference to political power.
International law will never eliminate political interests or guarantee justice. But abandoning it would leave those with the greatest military and economic power even freer to impose their will.
