Thai soldiers put a razor wire fence on land allegedly reclaimed from Cambodia.

The troops laid around two kilometres (1.24 miles) of concertina wire to secure the border line at the disputed Thmor Da area in Pursat, Cambodia, on January 6.

Spools of barbed wire stretched out in front of restaurants and shops, blocking Cambodian villagers from returning to their homes after both countries signed a peace agreement in late December.

The fence also blocked the Thmor Da casino, with Thai soldiers strictly preventing access to the area.

Thai forces have also built a Trump-style wall of shipping containers in Sa Kaeo province. They also converted the captured Ban Nong Chan area into a military stronghold with bunkers and rest areas for soldiers.

Thailand and Cambodia declared a ceasefire on December 27, ending weeks of conflict that left at least 26 Thai soldiers dead and one Thai civilian injured.

In Cambodia, the number of military fatalities is believed to be much higher, though regime chiefs have not revealed the actual figure.

At least 600,000 people have been displaced on both sides of the border.

Defence ministers from both nations signed the agreement at a border checkpoint. Among the conditions stipulated was the repatriation of 18 Cambodian soldiers being held by Thailand since July.

The second truce follows the collapse of an earlier flimsy peace pact brokered by US President Donald Trump in July, in a bid for a Nobel Peace Prize nomination.

Thai and Cambodian diplomats have travelled to China's Yunnan province for trilateral talks to 'consolidate' the ceasefire.
