Thailand Rebuts Cambodia at UN Forum, Defends Years of Aid Amid Border Tensions
At a UN ECOSOC development meeting in New York, Thailand invoked decades of assistance to Cambodia while accusing it of recent armed attacks that Bangkok says killed civilians and displaced hundreds of thousands.
Thailand used a United Nations economic development forum in New York to sharply rebut Cambodia’s remarks, arguing that decades of Thai support for Cambodian peacebuilding and development have been undermined by recent cross-border violence.
The exchange took place on April 22 during the UN Economic and Social Council (ECOSOC) Forum on Financing for Development Follow-up, where Thailand exercised a formal right of reply after a Cambodian delegation statement.
What is confirmed is that Thailand’s UN representative used the session to present a detailed account of both historical cooperation and recent tensions with Cambodia.
Thai officials said their country had supported Cambodia over several decades, including during its post-conflict reconstruction period, and had provided more than 17 million US dollars in development assistance, technical cooperation, and scholarships since the COVID-19 pandemic.
They also referenced Thailand’s role in hosting large numbers of Cambodian refugees during earlier conflicts and its broader contribution to Cambodia’s reintegration into regional and international frameworks.
At the same time, Thailand accused Cambodia of launching armed attacks in July and December 2025. According to the Thai statement, those incidents resulted in 19 civilian deaths, 51 injuries, and the displacement of more than 400,000 people, along with reported damage to civilian infrastructure.
These figures were presented as Thailand’s account to the UN forum and have not been independently verified within the same session records.
Thailand said it regarded the incidents as unprovoked and described its response as an exercise of self-defence under the UN Charter.
It also raised broader concerns about border instability, including landmine contamination and allegations of continued planting of mines, despite Cambodia’s longstanding demining commitments.
Cambodia’s specific response at the forum was not detailed in the same Thai statement, and it remains unclear how Phnom Penh addressed the allegations in real time during the exchange.
Previous UN discussions between the two countries have seen each side reject the other’s narrative, particularly regarding responsibility for border incidents and casualty figures.
The confrontation at ECOSOC reflects a broader deterioration in Thailand–Cambodia relations following renewed border clashes in 2025 that both sides have previously blamed on one another.
While ceasefire arrangements and diplomatic contacts have periodically been reported, the underlying disputes over security incidents and accountability remain unresolved.
For now, both governments continue to frame the relationship in sharply contrasting terms: Thailand emphasizing long-term assistance and regional cooperation, and also citing recent security threats, while Cambodia has in other fora rejected allegations of aggression and disputed responsibility for border violence.
