Due to recurrent altercations and a worsening humanitarian crises, the long-running border dispute between Thailand and Cambodia has intensified in recent weeks, gaining much international attention. A disputed group of historic Hindu temples, including the Preah Vihear temple, which is located along the boundary between the two Southeast Asian countries, is at the heart of this dispute. The situation raises serious concerns for regional stability and foreign visitors, as violence has forced over 120,000 citizens to flee their homes and governments have issued travel recommendations.
The main point of contention in the Thailand-Cambodia border conflict is the 11th-century Preah Vihear temple. Though the International Court of Justice (ICJ) ruled in 1962 that the temple lies within Cambodian territory, the surrounding 4.6-square-kilometre land remains disputed.
Tensions reignited after the temple was designated a UNESCO World Heritage Site in 2008, with both nations deploying troops to the border shortly thereafter. Sporadic clashes have ever since broken out, with periodic ceasefires violations failing to resolve the territorial differences. The temple complex and surrounding archaeological zones are historically significant to both countries, and associated with deepening nationalist sentiments and diplomatic impasses.
Since early July 2025, clashes have only intensified along the contentious border zone. According to a news source, artillery shelling and ground skirmishes have been reported near the disputed area, leading to hostility and as a result over 120,000 civilians fleeing their homes. Both Cambodian and Thai militaries have accused each other of violating ceasefire terms.
The Cambodian Red Cross has stated that at least 90,000 civilians have been displaced within Cambodian provinces bordering Thailand. In Thailand, more than 30,000 residents have been relocated from border districts.
While sporadic fighting has been reported since 2008, the scale of this month’s violence is the most significant since 2011, when both countries saw dozens of casualties over similar disputes.
The ICJ ruling in 1962 awarded the temple to Cambodia, but ambiguity over the adjacent land kept the matter in a grey area. In 2013, the ICJ reaffirmed Cambodia’s sovereignty over the temple complex and urged both nations to withdraw troops from the vicinity.
Despite the verdict, Thailand did not fully vacate its military presence from surrounding hills and access roads. In 2024, Cambodia submitted further evidence to the ICJ requesting enforcement measures, but no resolution has been reached.
The ASEAN regional bloc has also called for diplomatic engagement, but bilateral talks between the two governments remain stalled as military tensions override negotiations.
As the border conflict escalates, several countries have issued travel advisories for their citizens. India, in particular, has released a detailed advisory urging nationals to avoid specific areas.
According to various news sources, the Indian Embassy has recommended avoiding the following areas:
1. Preah Vihear Province (Cambodia)
2. Oddar Meanchey Province (Cambodia)
3. Banteay Meanchey Province (Cambodia)
4. Surin Province (Thailand)
5. Sisaket Province (Thailand)
6. Buriram Province (Thailand)
7. Ubon Ratchathani Province (Thailand)
The advisory, released on 24 July 2025, cites security concerns and the risk of escalation in border zones. It also urges Indian nationals already in these provinces to remain in contact with the embassy and local authorities.
Embassies of other countries including the United States, United Kingdom, and Australia have also issued similar advisories, instructing their citizens to avoid travel to the affected regions and to exercise caution if travelling elsewhere in both countries.
Tourism, which is a vital economic sector for both Thailand and Cambodia, is already witnessing deep disruption. Popular temple circuits in northern Cambodia have seen sharp declination in footfall. Several border crossings, especially the Chong Chom–O Smach checkpoint, have been closed indefinitely.
Airlines operating between Bangkok and Siem Reap have not yet suspended services, but security screenings and delays have lengthened. Tour operators across Southeast Asia are re-routing itineraries to avoid affected areas, particularly around the Dangrek Mountain Range where most clashes are concentrated.
Thailand's Defence Ministry has stated that the military is acting in defence after “provocations” from Cambodian forces. Meanwhile, Cambodian officials claim that Thai troops shelled civilian areas near Preah Vihear.
Both sides have indicated willingness to return to negotiations but have not yet agreed on terms. International agencies including the UNHCR and ICRC are coordinating relief efforts for displaced populations.
