South East Asia's top diplomats are set to meet Monday in Malaysia to end deadly border clashes between Thailand and Cambodia that have killed at least 41 people and displaced close to one million others.

They will seek to revive a ceasefire that was brokered in July by Malaysia as chair of the Association of Southeast Asian Nations (ASEAN) and US President Donald Trump.

This meeting marks the first official discussions since the fighting resumed on December 8, with both countries exchanging blame for the resurgence of hostilities.

The roots of this conflict date back over a century to the period following the French colonial administration of Cambodia.

The ongoing violence has seen artillery exchanges along the complex 800 km (500-mile) border, with Thailand conducting air strikes targeting Cambodian military positions.

Malaysian Prime Minister Anwar Ibrahim expressed cautious optimism for the upcoming talks, emphasizing the need for both parties to secure a lasting peace.

Cambodia is advocating for the restoration of peace and neighborly relations, while Thailand stresses the need for a declaration of ceasefire before any genuine dialogue can commence.

Efforts for mediation are also being made by the US and China, with US Secretary of State Marco Rubio expressing hopes for a ceasefire resolution within the coming days.

China's commitment to facilitating dialogue was reaffirmed by its special envoy for Asian affairs, enhancing international efforts aimed at resolving tensions in the region.
