Deadly Thai-Cambodian dispute puts Asean's relevance on the line
The escalation underscores Asean's limitations in handling intra-regional disputes and raises fresh questions about its relevance in managing crises among its own members.
Follow our live coverage here.
SINGAPORE – Asean's continuing silence on mounting tensions between Thailand and Cambodia is once again testing its longstanding principle of non-interference.
Deadly clashes between its two member states on July 24 left at least 12 dead more than two months after border hostilities reignited.
The escalation underscores Asean's limitations in handling intra-regional disputes, experts told The Straits Times, and raises fresh questions about its relevance in managing crises among its own members.
'It is institutional inertia,' said Mr Andrew Mantong, a researcher at Indonesia's Centre for Strategic and International Studies (CSIS).
'The region has spent decades building platforms and mechanisms for peace. Yet when war erupts in its backyard, it is diplomacy by absence.'
At least 12 Thais, mostly civilians, have been killed in the latest outbreak of a longstanding border dispute. Fighting erupted in a contested area, with Cambodia accused of firing rockets into a Thai village and attacking a hospital, while Thailand launched air strikes on Cambodian military targets.

In response, Thailand has closed its entire border and urged its citizens to leave Cambodia.
Phnom Penh has downgraded diplomatic ties, accusing Bangkok of using excessive force.
The current flare-up began in May, when a Cambodian soldier was killed during a brief exchange of gunfire. Tensions have steadily escalated since, culminating in the recent air strikes and cross-border shelling.
Asean has remained publicly silent throughout, although some individual member states have called for peace.
The conflict was also not raised at the recent Asean Foreign Ministers' Meeting in Kuala Lumpur.
Malaysia is the current Asean chair and when asked about the issue during a press conference on July 11, Malaysia's Foreign Minister Mohamad Hasan called it a bilateral issue and reaffirmed the group's traditional stance of non-interference.
While Asean has long prided itself on consensus-building and neutrality, Mr Andrew of CSIS said its silence in the face of open conflict is unwise and risks diminishing its standing on the world stage.
That credibility has taken a further hit as Cambodia seems to have bypassed the grouping by appealing directly to the United Nations.
On July 24, the Cambodian media published Cambodia's Prime Minister Hun Manet's letter to the UN Security Council's president, Pakistan's envoy Asim Iftikhar Ahmad, calling for an urgent meeting of the 15-member body.
It is the first time in more than a decade that an Asean member has made such a request.
Cambodia also made the previous request in 2011, when artillery exchanges with Thailand near the Preah Vihear temple prompted Phnom Penh to seek international intervention.
The UN Security Council is expected to convene in the coming days, but observers say any outcome will likely mirror that of 2011, which had included calls for maximum restraint and for Asean to play a more active role in dispute resolution.
Still, the referral itself is telling. If countries in the region feel compelled to turn to New York to manage tensions with their neighbours, it reflects a worrying lack of trust in Asean, or in any regional third party, to help defuse a conflict in its own backyard.
'The gap between Asean's aspirational vision and its operational readiness has rarely been this exposed; and I am worried that the current geopolitical contour will make it more frequently exposed,' said Mr Andrew.
On July 24, Malaysian Prime Minister Anwar Ibrahim said that he had sent messages to the prime ministers of Cambodia and Thailand, hoping to speak with them personally.
Calling the situation worrying, he said that both countries are key members of Asean and close neighbours to Malaysia, adding that he hoped they would de-escalate tensions and return to the negotiating table.
Trust a key issue?
Some analysts say a key factor holding Asean back is the lack of trust between the parties involved. Asean Secretary-General Kao Kim Hourn is Cambodian, and some observers argue that Thailand may not view him as a neutral mediator.
A similar impasse occurred in 2008, when Cambodia rejected mediation by then Asean secretary-general Surin Pitsuwan, a veteran Thai diplomat, during border clashes near the Preah Vihear temple.
After mediation failed, the conflict simmered without formal resolution, until 2011, when Cambodia turned to the UN following renewed violence at the same border area.
However, others say the problem is structural, not personal. Ms Joanne Lin, a senior fellow at the ISEAS – Yusof Ishak Institute, said the issue lies with Asean's institutional design, not the nationality of its representatives.
'The Secretariat does not have the mandate to lead politically, and decisions must come from member states,' she said, noting how back in 2011, Cambodia had similarly turned to the UN.
Eventually, the case went to the International Court of Justice, which ruled in 2013 that Cambodia had sovereignty over the temple and ordered Thai troops to withdraw.
That verdict helped ease tensions, but more than a decade on, diplomatic relations between the two neighbours are at their lowest in years.
Bilateral channels, said Ms Lin, may no longer be viable.
Still, she believes Asean has a narrow window to act. Neutral members like Indonesia or Singapore could potentially step in to broker talks or quietly facilitate de-escalation.
In the last bout of fighting between the two countries in 2011 – when Indonesia was the Asean chair – then Indonesian foreign minister Marty Natalegawa undertook shuttle diplomacy to defuse tensions.
He held talks with both sides in their respective capitals, and also subsequently met with the UN Security Council alongside the two nations' foreign ministers.
With the current ignition of tensions, Ms Lin said, 'if Asean doesn't step up, it risks being sidelined in its own region. China, which has close ties with both countries, has already shown interest in stepping in'.
China on July 24 expressed deep concern over the border clashes and offered to play a constructive role in promoting peace, urging both sides to resolve the dispute through dialogue and pledging to remain fair, impartial and supportive of regional stability.
Asean would prefer that the two countries resolve the conflict bilaterally, as both are members of the regional organisation.
But if that is not possible, they should resolve it peacefully through third-party mediation, said Dr Mustafa Izzuddin, a senior international affairs analyst at business consultancy Solaris Strategies Singapore.
However, the non-response from Asean – as of July 24 – signifies 'collective fatigue' on the part of the group in dealing with conflict in the region, he added.
The group has faced criticism for its failure to implement the five-point peace plan with Myanmar's military regime, as well as its inability to conclude negotiations on a code of conduct for the South China Sea, aimed at managing tensions amid overlapping maritime claims.
'Asean is acting strategically so that it does not need to bite off more than it can chew as a multilateral organisation with a multitude of interests that are focused on regional integration,' said Dr Mustafa.

India to maintain Russian oil imports despite Trump threats, government sources say
Sign up now: Get ST's newsletters delivered to your inbox US President Donald Trump has threatened 100 per cent tariffs on US imports from countries that buy Russian oil unless Moscow reaches a peace deal with Ukraine. NEW DELHI - India will keep purchasing oil from Russia despite US President Donald Trump's threats of penalties, two Indian government sources told Reuters on Aug 2, not wishing to be identified due to the sensitivity of the matter. On top of a new 25 per cent tariff on India's exports to the US, Mr Trump indicated in a Truth Social post in July that India would face additional penalties for purchases of Russian arms and oil. On Aug 1, Mr Trump told reporters he had heard that India would no longer be buying oil from Russia. But the sources said there would be no immediate changes. 'These are long-term oil contracts,' one of the sources said. 'It is not so simple to just stop buying overnight.' Justifying India's oil purchases from Russia, a second source said India's imports of Russian grades had helped avoid a global surge in oil prices, which have remained subdued despite Western curbs on the Russian oil sector. Unlike Iranian and Venezuelan oil, Russian crude is not subject to direct sanctions, and India is buying it below the current price cap fixed by the European Union, the source said.

Indian government authorities did not respond to Reuters' request for official comment on its oil purchasing intentions. However, during a regular press briefing on Aug 1, foreign ministry spokesperson Randhir Jaiswal said India has a 'steady and time-tested partnership' with Russia. 'On our energy sourcing requirements... we look at what is there available in the markets, what is there on offer, and also what is the prevailing global situation or circumstances,' he said. The White House did not immediately respond to requests for comment. India's top supplier Mr Trump, who has made ending Russia's war in Ukraine a priority of his administration since returning to office this year, has expressed growing impatience with Russian President Vladimir Putin in recent weeks. He has threatened 100 per cent tariffs on US imports from countries that buy Russian oil unless Moscow reaches a peace deal with Ukraine. Russia is the leading supplier to India, the world's third-largest oil importer and consumer, accounting for about 35 per cent of its overall supplies. India imported about 1.75 million barrels per day of Russian oil from January to June this year, up 1 per cent from a year ago, according to data provided to Reuters by sources. But while the Indian government may not be deterred by Mr Trump's threats, sources told Reuters this week that Indian state refiners stopped buying Russian oil after July discounts narrowed to their lowest since 2022 - when sanctions were first imposed on Moscow - due to lower Russian exports and steady demand. Indian Oil, Hindustan Petroleum, Bharat Petroleum and Mangalore Refinery Petrochemical have not sought Russian crude in the past week or so, four sources told Reuters. Nayara Energy - a refinery majority-owned by Russian entities, including oil major Rosneft, and major buyer of Russian oil - was recently sanctioned by the EU. Nayara's chief executive resigned following the sanctions, and three vessels laden with oil products from Nayara Energy have yet to discharge their cargoes, hindered by the new EU sanctions, Reuters reported last week.

Amsterdam Pride parade blends celebration and protest in LGBTQ+ show of solidarity
Sign up now: Get ST's newsletters delivered to your inbox AMSTERDAM - Around 80 colorful pride boats sailed through Amsterdam's World Heritage canals on Saturday in the finale of a week-long celebration in the city that stood in stark contrast to recent crackdowns on LGBTQ+ rights in fellow EU member state Hungary. While the flotilla is not political, attendees used the occasion to criticise conflicts or world leaders for their stance on LGBTQ+ rights. Thehany Gilmore, a 43-year-old Dutch-Caribbean dressed in a leather outfit with a whip, said banning of the Budapest pride parade "is a form of oppression." "People everywhere should have their own pride to be able to represent who they are," she said. Palestinian flags were spotted among the crowd of revelers, and Dutch police arrested four activists who had jumped in the water to vandalize the boat in protest over its listings in settlements in Israeli-occupied territories. Others criticized U.S. President Donald Trump, whose administration implemented anti-trans policies and cut funding for international aid programs, dealing a setback to HIV prevention efforts in Africa. Some waved a hybrid U.S./Pride flag, while one boat declared itself a 'Trump-Free Pride Boat' with signs reading 'Trans Rights Are Human Rights.' Another featured mock graveyards and the message 'Trump's Actions Kill. Love Saves Lives,' highlighting fears over U.S. AIDS funding cuts. "Amsterdam Pride is... about expressing yourself, showing who you are, being grateful for the freedom that we have in Europe. The U.S. really needs to reinvent itself... be more open about people," 40-year-old Michael Jacobs, who hails from Dutch port city Rotterdam, said. "Don't judge people for who they are. Just love each other." REUTERS

US envoy Steve Witkoff meets Israeli hostage families in Tel Aviv
Sign up now: Get ST's newsletters delivered to your inbox US envoy Steve Witkoff (left) arriving on Aug 2 for a closed meeting with the families of Israeli hostages still being held by Hamas militants in the Gaza Strip. TEL AVIV - US envoy Steve Witkoff met anguished relatives of Israeli hostages still held in Gaza on Aug 2, as fears for the captives' survival mounted almost 22 months into the war sparked by Hamas' October 2023 attack. Mr Witkoff was greeted with some applause and pleas for assistance from hundreds of protesters gathered in Tel Aviv, before going into a closed meeting with the families. The Hostages and Missing Families Forum confirmed the meeting was under way and videos shared online showed Mr Witkoff arriving as families chanted 'Bring them home!' and 'We need your help.' The visit came one day after Mr Witkoff visited a US-backed aid station in Gaza, to inspect efforts to get food into the devastated Palestinian territory. Mr Yotam Cohen, brother of 21-year-old hostage Nimrod Cohen, told AFP: 'The war needs to end. The Israeli government will not end it willingly. It has refused to do so. 'The Israeli government must be stopped. For our sakes, for our soldiers' sakes, for our hostages' sakes, for our sons and for the future generations of everybody in the Middle East.' Of the 251 hostages taken during the Hamas attack, 49 are still being held in Gaza, including 27 the Israeli military says are dead. Top stories Swipe. Select. Stay informed.

'Horrifying acts' Hamas attempted to maintain pressure on the families, releasing a video of one of the hostages – 24-year-old Mr Evyatar David – for the second time in two days, showing him looking emaciated in a tunnel. The video called for a ceasefire and warned that time was running out for the hostages. Mr David's family said their son was the victim of a 'vile' propaganda campaign and accused Hamas of deliberately starving their son. 'The deliberate starvation of our son as part of a propaganda campaign is one of the most horrifying acts the world has seen. He is being starved purely to serve Hamas' propaganda,' the family said. The United States, along with Egypt and Qatar, had been mediating ceasefire talks between Hamas and Israel that would allow the hostages to be released and humanitarian aid to flow more freely. But talks broke down in July and Prime Minister Benjamin Netanyahu's government is under increasing domestic pressure to come up with another way to secure the missing hostages, alive and dead. He is also facing international calls to open Gaza's borders to more food aid, after UN and humanitarian agencies warned that more than two million Palestinian civilians are facing starvation. 'Without rest' But Israel's top general warned that there would be no respite in fighting if the hostages were not released. 'I estimate that in the coming days we will know whether we can reach an agreement for the release of our hostages,' armed forces chief of staff Eyal Zamir said in a statement. 'If not, the combat will continue without rest.' Lieutenant-General Zamir denied that there was widespread starvation in Gaza. 'The current campaign of false accusations of intentional starvation is a deliberate, timed, and deceitful attempt to accuse the IDF (Israeli military), a moral army, of war crimes,' he said. Alongside reports from UN-mandated experts warning a 'famine is unfolding' in Gaza, more and more evidence is emerging of serious malnutrition and deaths among the most vulnerable Palestinian civilians. Ms Modallala Dawwas, 33, living in a displacement camp in Gaza City told AFP her daughter Mariam had no known illnesses before the war but had now dropped from 25kg to 10kg and was seriously malnourished. Hamas' 2023 attack resulted in the deaths of 1,219 people, mostly civilians, according to a tally based on official figures. Israel's campaign in Gaza has killed at least 60,332 people, mostly civilians, according to figures from the Hamas-run territory's health ministry, deemed reliable by the UN. Gaza's civil defence agency said Israeli fire killed 34 people in the territory on Aug 2. Civil defence spokesman Mahmud Bassal said five people were killed in an Israeli strike on an area of central Gaza where Palestinians were awaiting a food distribution by the US-backed Gaza Humanitarian Foundation. He added that the Aug 2 strikes mostly targeted areas near Gaza City in the north and Khan Younis in the south. AFP
