Explainer-Border tensions: What's behind the row between Thailand and Cambodia?
BANGKOK - Tension has been rising between Thailand and Cambodia following the killing of a Cambodian soldier in May during a brief exchange of gunfire at a disputed border area between the two Southeast Asian neighbours.
WHERE DOES THE DISPUTE ORIGINATE?
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. That map, which Thailand later contested, was based on an agreement that the border would be demarcated along the natural watershed line between the two countries.
In 2000, the two countries agreed to establish a Joint Border Commission to peacefully address overlapping claims, but little progress has been made towards settling disputes.
Claims over ownership of historical sites have raised nationalist tension between the two countries, notably in 2003 when rioters torched the Thai embassy and Thai businesses in Phnom Penh over an alleged remark by a Thai celebrity questioning jurisdiction over Cambodia's World Heritage-listed Angkor Wat temple.
WHAT WERE PREVIOUS FLASHPOINTS?
An 11th century Hindu temple called Preah Vihear, or Khao Phra Viharn in Thailand, has been at the heart of the dispute for decades, with both Bangkok and Phnom Penh claiming historical ownership. The International Court of Justice awarded the temple to Cambodia in 1962, but Thailand has continued to lay claim to the surrounding land.
Tension escalated in 2008 after Cambodia attempted to list the Preah Vihear temple as a UNESCO World Heritage site, leading to skirmishes over several years and at least a dozen deaths, including during a weeklong exchange of artillery in 2011.
Two years later, Cambodia sought interpretation of the 1962 verdict and the ICJ again ruled in its favour, saying the land around the temple was also part of Cambodia and ordering Thai troops to withdraw.
WHAT'S BEHIND RECENT TROUBLES?
Despite the historic rivalry, the current governments of Thailand and Cambodia enjoy warm ties, partly due to the close relationship between their influential former leaders, Thailand's Thaksin Shinawatra and Cambodia's Hun Sen, whose daughter and son respectively are now the respective prime ministers in their countries. Thaksin and Hun Sen also remain active in politics.
But nationalist sentiment has risen in Thailand after conservatives last year questioned the government's plan to negotiate with Cambodia to jointly explore energy resources in undemarcated maritime areas, warning such a move could risk Thailand losing the island of Koh Kood in the Gulf of Thailand.
Tensions also rose in February when a group of Cambodians escorted by troops sang their national anthem at another ancient Hindu temple that both countries claim, Ta Moan Thom, before being stopped by Thai soldiers.
The issue is a problem for Thai Prime Minister Paetongtarn Shinawatra, whose government is facing multiple challenges on the domestic front, including a stuttering economy facing steep U.S. tariffs.
Thailand's military, however, has ramped up the rhetoric with statements that have contrasted with the government's conciliatory tone, expressing readiness for a "high-level operation" if sovereignty comes under threat.
Paetongtarn later echoed the military's position but said a peaceful resolution of the disputes was Thailand's priority. The mixed messaging underlines the troubled history between the billionaire Shinawatra family and the royalist military, which toppled its governments in 2006 and 2014.
HOW IS THE ISSUE BEING RESOLVED?
After the May 28 clash, both countries quickly promised to ease tension, prevent more conflict and seek dialogue via their joint border commission at a meeting planned for June 14.
The neighbours have issued diplomatically worded statements committing to peace while vowing to protect sovereignty, but their militaries have been mobilising near the border, raising concerns about another flare-up.
Cambodia, meanwhile, said existing mechanisms were not working and it planned to refer disputes in four border areas to the ICJ to settle "unresolved and sensitive" issues that it said could escalate tensions.
Thailand has not recognised the ICJ's rulings on the row and wants to settle it bilaterally. REUTERS

Thailand and Cambodia reinforcing troops on disputed border after May skirmish, Thai minister says

For days, the two South-east Asian governments have exchanged carefully worded statements committing to dialogue after a brief skirmish in an undemarcated border area on May 28 in which a Cambodian soldier was killed. But Mr Phumtham Wechayachai, who also serves as Thailand's deputy prime minister, said that during talks bilateral talks held on June 5, Cambodia had rejected proposals that could have led to a de-escalation. "Furthermore, there has been a reinforcement of military presence, which has exacerbated tensions along the border," Mr 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 June 7, 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. A spokesperson for Cambodia's foreign ministry did not immediately respond to questions from Reuters. The military reinforcements come despite efforts by Malaysian Prime Minister Anwar Ibrahim, who is the current chair of the Association of South-east Asian Nations (Asean) bloc, and China to reduce tensions. Thailand and Cambodia have for more than a century contested sovereignty at various undemarcated points along their 817km 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 weeklong 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 Mr Thaksin's daughter and Mr 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 June 6 that 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. Mr Phumtham reiterated in his June 7 statement that Thailand does not recognise the jurisdiction of the court and proposed that all boundary-related issues be resolved through bilateral negotiations.

India PM Modi opens strategic railway in contested ‘crown jewel' Kashmir
Prime Minister Narendra Modi on June 6 opened a strategic railway line to Kashmir he called 'the crown jewel of India'. PHOTO: EPA-EFE SRINAGAR - Prime Minister Narendra Modi made his first visit to Kashmir on June 6 since a conflict with arch-rival Pakistan, opening a strategic railway line to the contested region he called 'the crown jewel of India'. Mr Modi launched a string of projects worth billions of dollars for the divided Muslim-majority territory, the centre of bitter rivalry between India and Pakistan since their independence from British rule in 1947. Nuclear-armed India and Pakistan fought a four-day conflict in May, their worst standoff since 1999, before a ceasefire was agreed on May 10. 'Pakistan will never forget... its shameful loss,' the Hindu nationalist premier told crowds a month since India launched strikes on its neighbour after an attack on tourists in Kashmir. 'Friends, today's event is a grand festival of India's unity and firm resolve,' Mr Modi said after striding across the soaring bridge to formally launch it for rail traffic. 'This is a symbol and celebration of rising India,' he said of the Chenab Bridge which connects two mountains. New Delhi calls the Chenab span the 'world's highest railway arch bridge', sitting 359m above a river. While several road and pipeline bridges are higher, Guinness World Records confirmed that Chenab trumps the previous highest railway bridge, the Najiehe in China. 'Our troubles' Mr Modi said the railway was 'an extraordinary feat of architecture' that 'will improve connectivity' by providing the first rail link from the Indian plains up to mountainous Kashmir. With 36 tunnels and 943 bridges, the new railway runs for 272km and connects Udhampur, Srinagar and Baramulla. It is expected to halve the travel time between the town of Katra in the Hindu-majority Jammu region and Srinagar, the main city in Kashmir, to around three hours. The new route will facilitate the movement of people and goods, as well as troops, that was previously possible only via treacherous mountain roads and by air. Mr Modi's Hindu nationalist government revoked Kashmir's limited autonomy and took the state under direct rule in 2019. Pakistan's foreign ministry in a statement said India's 'claims of development... ring hollow against the backdrop of an unprecedented military presence, suppression of fundamental freedoms, arbitrary arrests, and a concerted effort to alter the region's demography'. Around 150 people protested against the project on the outskirts of Muzaffarabad, the capital of Pakistan-administered Kashmir. 'We want to tell India that building bridges and laying roads in the name of development will not make the people of Kashmir give up their demand for freedom,' said Mr Azir Ahmad Ghazali, who organised the rally attended by Kashmiris who fled unrest on the Indian side in the 1990s. 'In clear and unequivocal terms, we want to say to the Indian government that the people of Kashmir have never accepted India's forced rule.' More than 70 people were killed in missile, drone and artillery fire during last month's conflict. The fighting was triggered by an April 22 attack on civilians in Indian-administered Kashmir that New Delhi accused Pakistan of backing, a charge denied by Islamabad. Rebel groups in Indian-run Kashmir have waged an insurgency for 35 years demanding independence for the territory or its merger with Pakistan. Mr Modi also announced further government financial support for families whose relatives were killed, or whose homes were damaged, during the brief conflict –- mainly in shelling along the heavily militarised de facto border with Pakistan, known as the Line of Control. 'Their troubles are our troubles,' Mr Modi said. REUTERS Join ST's Telegram channel and get the latest breaking news delivered to you.

India vows to keep up development in Kashmir after tourist attack
FILE PHOTO: Chairs and tables are scattered at the site of a suspected militant attack on tourists in Baisaran near Pahalgam in south Kashmir's Anantnag district, April 24, 2025. REUTERS/Adnan Abidi/File Photo India vows to keep up development in Kashmir after tourist attack NEW DELHI - India is committed to efforts to develop its restive territory of Jammu and Kashmir, Prime Minister Narendra Modi said on Friday, accusing neighbour Pakistan of seeking to destroy livelihoods there with April's deadly attack on tourists. He was speaking on his first visit to the Himalayan region since Islamist attackers targeted Hindu tourists in the popular Pahalgam area, killing 26 men, triggering hostilities between the nuclear-armed neighbours that ended in ceasefire last month. "The atmosphere of development that emerged in Jammu and Kashmir will not be hindered by the attack ... I will not let development stop here," Modi said in remarks after inaugurating infrastructure projects. Key among these was a $5-billion rail link between the Kashmir Valley and the rest of India, which has been more than 40 years in the making and features the world's highest railway arch bridge. Others include highways, city roads and a new medical college. India has accused Pakistan of backing the April attack, a claim denied by Islamabad, and they engaged in four days of fierce fighting last month before agreeing to a ceasefire. Pakistan aimed to disrupt the livelihoods of the poor in Kashmir, who rely heavily on tourism, Modi said, adding that he would face down any obstacle to regional development. Pakistan's foreign ministry did not immediately respond to a request for comment on Modi's remarks. Last month, Islamabad said a just and peaceful resolution of the Kashmir dispute was essential to ensure lasting peace in the region, known for its snow-topped mountains, scenic lakes, lush meadows, and tulip gardens. The region, which drew more than 3 million visitors last year, is at the heart of the hostility between the old foes, both of which claim it in full, but rule it in part and have fought two of their three wars over it. India also accuses Pakistan of supporting Islamist militants battling security forces in Jammu and Kashmir, but Islamabad denies the accusation. Trains run in the Kashmir Valley but the new link is its first to the wider Indian railway network. Apart from boosting the regional economy, it is expected to help revive tourism, which plummeted after the April attack.
