Thailand and Cambodia reinforcing troops on disputed border after May skirmish, Thai minister says
By Panarat Thepgumpanat and Devjyot Ghoshal
Thailand has reinforced its military presence along a disputed border with Cambodia, following an increase in troops on the other side, Thailand's defense minister said on Saturday.
Tensions between the two Southeast Asian countries have been simmering since a Cambodian soldier was killed on May 28 in a brief conflict in an undemarcated border area. For days, the two Southeast Asian governments have been exchanging carefully worded statements committing to dialogue.
But Phumtham Wechayachai, who also serves as Thailand's deputy prime minister, said Cambodia had rejected proposals in bilateral talks held on Thursday that could have led to a de-escalation.
"Furthermore, there has been a reinforcement of military presence, which has exacerbated tensions along the border," Phumtham said in a statement.
"Consequently, the Royal Thai Government has deemed it necessary to implement additional measures and to reinforce our military posture accordingly."
He did not provide details on the extent of reinforcements by either side.
In a separate statement on Saturday, the Thai army said Cambodian soldiers and civilians had repeatedly made incursions into Thailand's territory.
"These provocations, and the build-up of military forces, indicate a clear intent to use force," the Thai army said, adding that it would take control of all Thai checkpoints along the border with Cambodia.
Although border checkpoints between the two countries remain open, they may gradually become more restrictive, ranging from earlier closing times to complete closures, depending on security assessments in each area, Thai army spokesperson Winthai Suvaree said.
Thailand currently operates 17 official border crossings with Cambodia, spanning seven provinces along their shared 817-km (508 miles) frontier, government data shows.
A spokesperson for Cambodia's foreign ministry did not immediately respond to questions from Reuters on the Thai army's announcement.
"This is our stance, not to initiate conflict, but to defend ourselves," Cambodian Prime Minister Hun Manet said in speech earlier on Saturday.
"Our guiding principles are ... respect for international legal frameworks. These grounded strategies are key to safeguarding our nation's sovereignty," he said, adding that its armed forces were ready to defend against aggression.
Thailand remains committed to pursuing bilateral dialogue as a means to restore stability, a spokesperson for the Ministry of Foreign Affairs said on Saturday.
"The Thai side reaffirms its readiness to engage through established bilateral mechanisms, particularly the upcoming meeting of the Thailand-Cambodia Joint Boundary Commission (JBC), scheduled for June 14," Foreign Ministry spokesperson Nikorndej Balankura told reporters.
"We sincerely hope that the negotiations will proceed in good faith", he added.
The military reinforcements come despite efforts by Malaysian Prime Minister Anwar Ibrahim, who is the current chair of the Southeast Asian ASEAN bloc, and China to reduce tensions.
Thailand and Cambodia have for more than a century contested sovereignty at various undemarcated points along their 817 km (508 miles) land border, which was first mapped by France in 1907 when Cambodia was its colony.
Tension escalated in 2008 over an 11th-century Hindu temple, leading to skirmishes over several years and at least a dozen deaths, including during a week-long exchange of artillery in 2011.
Current governments in both countries, however, have enjoyed warm ties. Former leaders Thaksin Shinawatra of Thailand and Cambodia's Hun Sen have had a close relationship, and Thaksin's daughter and Hun Sen's son are now the incumbent prime ministers of their countries.
Still, nationalist sentiment has risen in Thailand and the Thai military said on Friday it is ready to launch a "high-level operation" to counter any violation of its sovereignty.
Cambodia said this week it would refer disputes over four parts of the border to the International Court of Justice and asked Thailand to cooperate.
Phumtham reiterated in his Saturday statement that Thailand does not recognise the jurisdiction of the court and proposed that all boundary-related issues be resolved through bilateral negotiations.

Thailand and Cambodia exchange heavy fire as fighting rages for second day
Thailand and Cambodia exchanged heavy artillery fire on Friday as their worst fighting in more than a decade stretched for a second day, despite calls from the region and beyond for an immediate ceasefire in an escalating border conflict that has killed at least 16 people. Thailand's military reported clashes from before dawn in the Ubon Ratchathani and Surin provinces and said Cambodia had used artillery and Russian-made BM-21 rocket systems. Authorities said 100,000 people had been evacuated from conflict areas on the Thai side. "Cambodian forces have conducted sustained bombardment utilizing heavy weapons, field artillery and BM-21 rocket systems," the Thai military said in a statement. "Thai forces have responded with appropriate supporting fire in accordance with the tactical situation." Both sides blamed each other for starting the conflict on Thursday at a disputed border area, which quickly escalated from small arms fire to heavy shelling in at least six locations 209 kilometers apart along a frontier where sovereignty has been disputed for more than a century. Journalists in Surin province reported hearing intermittent bursts of explosions on Friday, amid a heavy presence of armed Thai soldiers along roads and gas stations in the largely agrarian area.

The fighting erupted on Thursday just hours after Thailand recalled its ambassador to Phnom Penh the previous night and expelled Cambodia's envoy, in response to a second Thai soldier losing a limb to a landmine that Bangkok alleged had been laid recently by rival troops. Cambodia has dismissed that as baseless. The Thai death toll rose to 15 as of early Friday, 14 of them civilians, according to the health ministry. It said 46 people were wounded, including 15 soldiers. Cambodia's national government has not provided details of any casualties or evacuations of civilians. A government spokesperson did not immediately respond to a request for comment on the latest clashes. Meth Meas Pheakdey, spokesperson for the provincial administration of Cambodia's Oddar Meanchey province, said one civilian had been killed and five were wounded, with 1,500 families evacuated. Thailand had positioned six F-16 fighter jets on Thursday in a rare combat deployment, one of which was mobilized to strike a Cambodian military target, among measures Cambodia called "reckless and brutal military aggression." Thailand's use of an F-16 underlines its military advantage over Cambodia, which has no fighter aircraft and significantly less defense hardware and personnel, according to the London-based International Institute for Strategic Studies People wait in line to get food at a shelter in Thailand's Buriram province on Thursday. | REUTERS The United States, a long-time treaty ally of Thailand, called for an "immediate cessation of hostilities, protection of civilians and a peaceful resolution." Malaysian Prime Minister Anwar Ibrahim, the chair of the Association of Southeast Asian Nations, of which Thailand and Cambodia are members, said he had spoken to leaders of both countries and urged them to find a peaceful way out. "I welcome the positive signals and willingness shown by both Bangkok and Phnom Penh to consider this path forward. Malaysia stands ready to assist and facilitate this process in the spirit of ASEAN unity and shared responsibility," he said in a social media post late on Thursday.

Malaysia's Anwar Calls for Ceasefire Between Thailand and Cambodia
Conflict continues to rage at various points along the two nations' border, a day after fighting erupted at the disputed Ta Muen Thom temple. Malaysian Prime Minister Anwar Ibrahim has called on both Thailand and Cambodia to de-escalate the conflict along their shared border, where the two militaries continue to exchange heavy fire. Anwar, who holds this year's chairmanship of the Association of Southeast Asian Nations (ASEAN), said that he spoke with acting Thai Prime Minister Phumtham Wechayachai and Cambodian Prime Minister Hun Manet last night, in order to convey his government's 'deep concern' over the outbreak of violence. Fighting erupted between the Thai and Cambodian militaries yesterday morning, a day after a landmine explosion along a disputed stretch of the border injured five Thai soldiers, one seriously. Throughout the day, the two sides exchanged heavy fire at various points along the border. Fighting has reportedly continued along the border today. In a post on social media, Anwar said that he 'appealed directly to both leaders for an immediate ceasefire to prevent further hostilities and to create space for peaceful dialogue and diplomatic resolution.' 'I welcome the positive signals and willingness shown by both Bangkok and Phnom Penh to consider this path forward. Malaysia stands ready to assist and facilitate this process in the spirit of ASEAN unity and shared responsibility,' he added. 'I firmly believe that ASEAN's strength lies in its solidarity and that peace must always be our collective and unwavering choice.' At least one Thai soldier and 14 civilians, including children, have been killed so far in the conflict, Thailand's Ministry of Public Health said today, while 15 soldiers and 31 other civilians have been injured. Cambodia has been less forthcoming about casualties, but a Cambodian general based in Oddar Meanchey province said this morning that at least four civilians were wounded in yesterday's fighting there and that more than 4,000 people had been displaced from their villages along the border to evacuation centers. Thailand says that 131,456 civilians have been evacuated from affected areas. Both sides have blamed the other for the outbreak of fighting. Thailand claims that the conflict began when Cambodian soldiers fired unprovoked at a Thai military encampment close to Ta Muen Thom temple early yesterday morning. Conversely, Cambodia's government asserts that its troops retaliated after an 'unprovoked incursion' by Thai forces and 'acted strictly within the bounds of self-defense.' Fighting swiftly spread to other parts of the border, and both sides deployed heavy weaponry including multiple-launch rocket systems, artillery, and tanks. Cambodia fired Russia-made BM-21s and artillery shells into Thailand while the Thai military said that it scrambled F-16 jets to bomb Cambodian military targets. Cambodia has since accused Thailand of causing 'significant damage' to Preah Vihear temple, a UNESCO World Heritage Site that was the focus of a border conflict during 2008-2011, and of deploying cluster munitions along the border. Anwar's call for calm was echoed by the United Nations, European Union, the United States, Australia, and France, as well as several other ASEAN nations. Several governments have also warned their citizens against traveling to affected areas of the border. China, which maintains good relations with both Thailand and Cambodia, pledged to remain neutral in the current conflict, expressing hope that the two sides 'will resolve their issues properly through dialogue and consultation,' Chinese Foreign Ministry spokesman Guo Jiakun said yesterday. 'China has been and will continue to facilitate peace and dialogue in its own way, playing a constructive role in easing tensions and cooling down the situation,' he added. The U.N. Security Council will hold an emergency meeting to discuss the conflict, the AFP news agency reported, citing diplomatic sources. The unfolding conflict also poses another stiff challenge for ASEAN, which prides itself on having presided over an historic span of inter-state peace between its members since its founding in 1967. However, a key obstacle to a ceasefire, aside from the nationalist passions that have been stirred by the sight of civilian casualties and the fate of the (for Cambodians) highly symbolic Angkorian temple ruins along the border, is the bitter fallout between former leaders Hun Sen and Thaksin Shinawatra, whose children now serve as prime minister of each country. The relationship between the two political grandees collapsed after Cambodia's leak of a phone call between Hun Sen had with Prime Minister Paetongtarn Shinawatra last month. The leak was humiliating for the 38-year-old Thai leader; it also led to her suspension by the Constitutional Court pending an investigation into her conduct during the call, during which she accused a Thai general of siding with her political opponents. Thaksin later referred to the leak as a 'betrayal' by Hun Sen. While it is unclear whether the family feud contributed to the outbreak of war, is likely to prolong the brokering of a ceasefire. After Thaksin claimed yesterday on X that Hun Sen had ordered the attack on Thai territory 'after laying explosive traps along the border,' the Cambodian politician hit back on Facebook, accusing Thaksin of much the same thing. 'Under the pretext of taking revenge on Hun Sen, he is resorting to war, the ultimate consequence of which will be the suffering of the people,' he said. Then, this morning, Thaksin made another post on X. He said that many countries are 'offering help to mediate' in the Thai-Cambodian border clashes, but asked 'for some time because we need to let the Thai army teach that wily Hun Sen a lesson.' If nothing else, the conflict has laid bare where the real locus of authority in both countries' governments lies.
