A fresh clash between Thailand and Cambodia near their disputed border region has raised regional security concerns and drawn calls for de-escalation from China, which maintains close diplomatic ties with both Southeast Asian nations. The renewed conflict, which took place Thursday morning, involved an exchange of gunfire near the site of two ancient temples long at the heart of a territorial dispute.
At a press conference in Beijing, Chinese Foreign Ministry spokesperson Guo Jiakun emphasized China’s position as a neutral yet concerned regional actor. He urged both Thailand and Cambodia to resolve their differences through diplomatic means and pledged Beijing’s continued support for dialogue and peace-building efforts within the ASEAN framework.
“Thailand and Cambodia are both friendly neighbors of China and important members of ASEAN,” Guo stated. “Maintaining good-neighborly relations and properly handling differences serve the fundamental and long-term interests of both sides.”
He further added, “China is deeply concerned about the current escalation and hopes both parties will resolve the issue through dialogue and consultation… China, upholding a fair and impartial stance, has been and will continue to play a constructive role in promoting dialogue and de-escalation in its own way.”
The renewed fighting represents the most serious flare-up in recent years between the two ASEAN members, whose ties have historically oscillated between cooperation and confrontation.
According to initial reports from Agence France-Presse (AFP) and local media, exchanges of fire broke out shortly after dawn along a contested stretch of land near the Preah Vihear temple—an 11th-century Hindu shrine designated as a UNESCO World Heritage site in 2008. Both sides have blamed each other for initiating the violence.
A Cambodian military spokesperson claimed that Thai troops crossed into Cambodian territory and opened fire, prompting a defensive response. Meanwhile, Thai military officials accused Cambodian forces of firing first during what they described as a routine patrol on Thai soil.
Though no fatalities have yet been confirmed, local sources reported injuries on both sides and the evacuation of villagers from nearby settlements. Heavy artillery and small arms fire reportedly damaged infrastructure in the disputed zone.
The flare-up comes amid rising nationalist sentiment in both countries and a regional environment increasingly shaped by complex geopolitical rivalries.
The Thailand-Cambodia border has been a point of contention for more than a century, particularly around the Preah Vihear and Ta Moan Thom temples, both located in rugged terrain along the Dangrek Mountains. In 1962, the International Court of Justice (ICJ) awarded the Preah Vihear temple to Cambodia, a ruling Thailand reluctantly accepted. However, disputes over adjacent land persist.
The situation escalated sharply in 2008 after Cambodia successfully lobbied for the Preah Vihear temple to be listed by UNESCO as a World Heritage site. Thailand objected, arguing that the designation implicitly awarded Cambodia sovereignty over disputed territory. A series of violent border skirmishes followed between 2008 and 2011, resulting in dozens of deaths and extensive damage.
Although the ICJ issued a subsequent ruling in 2013 reaffirming Cambodian sovereignty over the immediate vicinity of the temple, it failed to fully resolve the underlying territorial disagreements. Tensions simmered throughout the 2010s, periodically flaring during military exercises or nationalist demonstrations in either country.
China’s reaction to the latest clash underscores its delicate balancing act in Southeast Asia. As the region’s largest economic power and a permanent member of the UN Security Council, Beijing has often styled itself as a proponent of “win-win cooperation” in the region. But that role is increasingly complicated by its own disputes in the South China Sea and its growing strategic rivalry with the United States and its allies.
China enjoys strong bilateral relationships with both Cambodia and Thailand. Cambodia is considered one of China’s staunchest allies in the region, with Phnom Penh repeatedly backing Beijing on contentious issues, including the South China Sea. China is also Cambodia’s largest investor and donor, funding infrastructure, defense, and industrial projects under the Belt and Road Initiative (BRI).
Thailand, on the other hand, while historically aligned with the United States through military and economic partnerships, has increasingly turned toward China in recent years, deepening cooperation in trade, infrastructure, and arms procurement.
By offering to play a “constructive role” while maintaining an “impartial stance,” Beijing seeks to preserve its relationships with both sides while promoting an image of regional stability and leadership within the ASEAN+3 framework.
