Beijing offered to help Thailand and Cambodia patch up relations after their deadliest border clashes in decades, as their foreign ministers met for talks in China.

Recall that a long-running border row between the Southeast Asian neighbors boiled over into conflict last month involving artillery bombardments, air strikes and infantry clashes, killing at least 43 people and forcing more than 300,000 others to flee their homes.

The two sides struck a ceasefire after five days of violence, following intervention from US President Donald Trump and agreed last week to extend the deal after talks between defence officials in Malaysia.

Beijing, Phnom Penh's main ally, has also been involved in mediation efforts, just as Chinese Foreign Minister Wang Yi met his Thai and Cambodian counterparts on the sidelines of a Mekong regional conference in Yunnan.

According to a Chinese foreign ministry statement, Wang told his counterparts that China is currently showing support to Cambodia and Thailand in engaging in dialogue, eliminating misunderstandings, and rebuilding mutual trust.

Wang also revealed that he believes the two sides can properly manage specific disputes and work hand in hand to tackle various global challenges.

Meanwhile, Thai Foreign Minister Maris Sangiampongsa thanked China for its mediating role and called for greater cooperation with Cambodia on removing landmines from the border area.

Local reports also have it that clashes have stopped since the ceasefire but several Thai soldiers have been wounded by landmine blasts, keeping tensions high.
