A Thai shop owner offered free supplies to soldiers on duty during the ongoing border clash with Cambodia.

CCTV footage shows Nirawit Somphakdi packing bags of snacks for a pair of troops visiting his store in Surin, Thailand, on July 28.

The officers then thanked him with a Thai gesture of gratitude.

Nirawit said the pair had driven several miles through deserted areas in search of a store after residents had fled from the fighting. His was the only one still open.

He said: ‘I had already planned that if soldiers passed my shop, I would give them supplies for free. I did not tell them immediately because I was worried they would be too embarrassed to get anything if all of it was free, so I waited until they finished shopping before telling them.

'I told them they could always visit my shop and thanked them for taking care of civilians.'

Despite the ongoing conflict, Nirawit said he chose to stay and man his shop because he felt sorry for the other locals who refused to evacuate.

The bloody military confrontation flared in long-disputed border areas as Thailand and Cambodia accused each other of instigating the violence on July 24.

The Thai army claimed the clash began when six armed Cambodian soldiers approached a Thai outpost after a drone was heard near a disputed Khmer temple. Thai troops said they shouted warnings and claimed the Cambodians opened fire first.

However, Cambodia's Defence Ministry accused Thailand of provoking the violence, saying its forces acted in self-defence.

Officials said at least 43 people have been killed and more than 300,000 displaced on both sides of the border.

Both sides have reached a truce at midnight on Monday, following talks facilitated by Malaysian Prime Minister Anwar Ibrahim, chair of the Association of Southeast Asian Nations (ASEAN).

He said: 'This is a vital first step toward de-escalation and the restoration of peace and security.'

US President Donald Trump had earlier threatened to pause trade deals with both countries if clashes continued.

He said after the ceasefire was forged: 'By ending this War, we have saved thousands of lives ... I have now ended many Wars in just six months — I am proud to be the President of PEACE!'

However, Thai authorities accused Cambodia of allegedly violating the armistice, claiming Khmer soldiers were firing into Thai territory until Wednesday morning.

Thai government spokesman Jirayu Huangsab said the Thai army have 'maintained control of the situation' and the general conditions along the border were 'normal'.
