Tensions Explode Across the Border

 

Border clashes between Thailand and Cambodia have resulted in a deadly standoff, killing at least 16 and displacing tens of thousands. Artillery fire marks the worst fighting in over a decade, as disputes over ancient temples fuel ongoing hostilities, leaving both countries on high alert.

 

Current Situation: A Nation on Edge

 

Heavy fighting erupted early Thursday near a contested ancient temple, quickly spreading along the disputed frontier. Thailand retaliated by withdrawing its ambassador, expelling Cambodia’s envoy, and deploying F-16 fighter jets, while Cambodia responded with truck-mounted rocket launchers. The escalating violence has led to the evacuation of approximately 130,000 Thais and 12,000 Cambodian families.

 

Roots of Dispute: A Century-Old Rivalry

 

The conflict dates back to 1907, when the border was first mapped by France during its colonial rule over Cambodia. A contentious map based on a natural watershed line sparked disagreements. Despite the formation of a Joint Boundary Commission in 2000, progress has stalled, with unresolved claims, particularly involving historical sites, heightening tensions.

 

Historical Flashpoints: Preah Vihear Temple

 

A significant flashpoint is the Preah Vihear temple, a historic Hindu site claimed by both nations. In 1962, the International Court of Justice awarded the temple to Cambodia, but surrounding land disputes persisted. Tensions peaked in 2008 when Cambodia proposed the temple for UNESCO World Heritage status, resulting in recurrent military clashes and casualties.

 

Recent Triggers: National Pride and Energy Disputes

 

Despite close governmental ties, nationalist fervour flared in Thailand after debates over joint energy resource explorations with Cambodia. In February, tensions worsened when Cambodians sang their anthem at a contested temple, prompting a military response from Thai soldiers.

 

Further complications arose when a conversation between Thailand's then-premier Paetongtarn Shinawatra and Cambodia’s Hun Sen was leaked, leading to political backlash and her suspension.

 

Resolving the Crisis: Diplomatic Moves and Military Mobilisation

 

In the wake of recent conflicts, both countries committed to seeking dialogue via their joint border commission. However, Cambodia plans to escalate unresolved issues to the International Court of Justice, a move Thailand opposes in favour of bilateral resolution.

 

Following Thursday’s clashes, Cambodia appealed to the United Nations Security Council to address what it terms as Thai aggression, while Thailand insists negotiations can only proceed if Cambodia halts its military actions, reported the Bangkok Post.

 

The fragile peace along the Thailand-Cambodia border remains in jeopardy as both nations struggle to balance territorial sovereignty with diplomatic compromise.

So there we have the nub of the issue - colonialism. The French draw an arbitrary border in 1907 and the nations are fighting still.

The British drew an arbitrary line through Punjab in 1948 and we have two nuclear armed nations snarling at each other.

The Balfour Declaration of 1918 didn't actually draw any lines and now we have mass starvation and bombing of already long oppressed people.

All stand for your relevant national anthems please.

Exactly, which is why the colonizers should keep their noses out of it. Let Thailand and Cambodia figure it out, if someone has to get their ass kicked to put and end to this, then so be it!

[Sydebolle]

The French demarcation of 1906 was presented to the court of Siam and Cambodia; both accepted and that dealt with that issue. In 1929 a Royal Princess of the Thai court wanted to visit a Khmer temple (Khao Phra Viharn) and requested permission to do so with the Cambodia Crown. 
Needless to say that she was of course granted the placet. Only once UNESCO got involved the whole thing escalated at the ICJ in the early 60s when the Thais started to refuse acceptances which had been sealed more than half a century before. 

Nowadays it is a token of excuse to explain Thailands bickering on the political stage; 2011 it was the yellow shirts against the red shirts and this time it is Pheu Thai (i.e. former red shirts) against Hun Sen as both leaders, Thaksin and Hun Sen think they are smarter than their opponent. 

Do you think that any Thai is seriously interested in the rugged jungle area of the Dong Rak mountains; nor do you think any Cambodian in Phnom Penh would really care? Both, Thailand and Cambodia were nowhere when those magnificent temple compounds with Hindu traces were built in the heydays of the Khmer Kingdom. Neither state existed so it is nothing but two naughty kids which need a proper smack to put the back into their pen!

Kindergarten warfare explained!

Very good summary, but I think the Treaty was 1907, and it included the 11 map set which defined the border. There is little doubt in my mind that Captain Bertrand was deliberately tricky in diverting the border around Prah Vihear, but there was no-one watching him. Not only did the Siamese not send surveyors they didn't even send observers, and they accepted the 11 maps drawn up by the French and issued them to foreign governments and local officials (all from ICJ Court documents). Then before the ICJ in 1962 they tried to claim that (i) they hadn't agreed to the maps, even though they were attached to the Treaty they had signed, or (ii) they didn't understand that the line had been drawn in the wrong place by Captain Bertrand. Since it was 55 years later it is hardly surprising that the ICJ basically said, you have left it a bit late to claim the maps are wrong.

Now we are left with the incredible difficulty of defining an inernational border. To do so on paper is quite easy, by darwing a line such as the 49th parallel, but then it is quite hard to define that line on the ground. Today we can do it instantly with GPS, but back in 1907 when they only had theodolites it was very much more difficult. That was why the Joint Border Commission opted to change it from a line on a map to follow geographical features such as a river or a mountain ridge. That is much easier to identify on the ground, but very difficult to draw on a map, and also rivers do move with time. Throw into the mix a tricky French surveyor being left to his own devices by the Siamese surveyors, and you have the current mess. When there are two parties, and one says "the border is here", while the other says "No it isn't, it's here", there is unlikely to be any agreement, which is why someone like the ICJ is necessary. I am quite sure Thailand would have accepted the ICJ decision if it had been in their favour, but it wasn't, so they didn't. Just bad losers.

In the end, an agreed shared zone for the land which has changed hands over rmany centuries may be the best solution, but the nationalists probably won't allow it.

Nobody. My understanding is that the conflict is all about potential natural gas deposits off Koh Koot. Something about profit sharing.

That one didn't draw any lines for a reason.  The mission here was expansion and land grabbing from the start.

The autocorrect was creating this confusion. A "plazet" roots in the German language and is used in other languages also as "agreement", "approval" - like the "déjà-vu" being borrowed from French for "seen already", "happened before" etc. 

A play of words .......

Construction of the Preah Vihear temple began in the 9th century A.D..  It wasn't until the 11th century that rulers of the Khmer Empire began to convert from Hinduism to Buddhism.

[Hellfire]

Do Cambodians really need that plot of land? Is it truly a priority for them? I doubt it. The ones stirring all this up are nothing but criminals, playing with human lives.

In old French it means "Writing addressed to a king, to a minister to be granted a grace, a favor, a petition..." From the latin verb "placere" (to please)

No, in French, the word "placet" comes from the Latin placet, meaning "it pleases" or "may it please." And indeed, it directly ties in with the expression "please the king"—a classic expression of deference in petitions addressed to the sovereign. Which makes perfect sense here. "Plazet" comes from latin too. The French borrowed it from latin as the German did.

Close, but no coconut.

 

When Thaksin was PM, he signed a Memorandum of Understanding with Hun Sen to explore ways of resolving the disputed offshore waters, the overlapping claims area, or OCA, with a view to joint exploration and mutual benefit. Then he lost the job, ran away, self-imposed exile, return, etc..

 

About 6 or 8 months ago, Pheu Thai raised the prospect of progressing the languishing MoU into reality. I recall this happened after Thaksin visited his old chum, or vice versa. The oil and gas industry pricked up its ears, such was the interest in a chunk of prospective subsurface finally being opened up in the OCA.

 

However, the opposition, nationalists and the navy all got on the "surrendering sovereignty" bandwagon and sunk the whole idea. That's where the notion of giving up Koh Koot first gained traction although the maps that popped up on Thai media to support this were not based on any agreed cartography. They also ignored the Cambodians when they said that they had no claim, and no plans to claim Koh Koot. The opponents also argued that Cambodia could get more oil or gas than Thailand, ignoring the fact that what lies below the sea bed isn't determined by any straight line on the surface, be it agreed or otherwise. Fundamentally, they don't want to share anything.

 

Since it's believed that Cambodian military build-up started last February, it's not too much of a stretch to consider that Hun Sen, pissed off by his buddy's inability to deliver on their agreement, and also needing to get an increasingly disillusioned population firmly behind his son, who only became PM in the summer of 2023, came up with this border folly.

You're all wrong. This is a proxy war between China for the Cambodian side USA for the Thai side. It's all about USA trying to reduce China's influence in the region. Plus it's about the casinos (existing and planned) and the gang call centers. Together. A multi million dollar income for the Sen family.

This might be a reason:

A disputed area in the Gulf of Thailand, known as the Overlapping Claims Area (OCA), is believed to contain significant natural gas and oil reserves, but exploration has been stalled due to a territorial dispute between Thailand and Cambodia. This 27,000 sq km area is estimated to hold up to 11 trillion cubic feet of natural gas, and potentially large quantities of condensate and oil.
