China has expressed support for Thailand and Cambodia in resolving their border dispute and offered to provide assistance based on the wishes of both nations, Foreign Minister Wang Yi said.

Wang said China supports the Southeast Asian countries in strengthening dialogue and eliminating misunderstandings, adding he hopes they would rebuild mutual trust and restore friendship.

He met his Thai and Cambodian counterparts separately and also convened a three-way conversation on the sidelines of the Lancang-Mekong Cooperation Foreign Ministers' Meeting in Yunnan province.

Wang said China hopes the two countries could reopen border crossings as soon as possible, a Foreign Ministry statement said.

China also promised support and assistance for landmine clearance in the border areas of Cambodia and Thailand, and the three ministers agreed to continue communication in a "flexible manner".

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, his ministry said in a statement on social media platform X.

Cambodian Foreign Minister Prak Sokhonn said his country is fully committed to the peace efforts.

Thailand and Cambodia have wrangled for decades over border territory and a border conflict erupted last month after the killing of a Cambodian soldier in a skirmish late in May. It was the worst fighting in more than a decade and only eased after a ceasefire was struck in late July. (Agencies)
