Thailand has reinforced its military presence along a disputed border with Cambodia, following an increase in troops on the other side, Thailand's defence minister said on Saturday. Tensions between the two Southeast Asian countries have been simmering since a Cambodian soldier was killed on May 28 in a brief conflict in an undemarcated border area.

Thailand’s top army official designated commanders of two task forces to oversee border crossings with Cambodia as tensions simmer following a skirmish in late May.

Tensions have escalated between Thailand and Cambodia following the death of a Cambodian soldier in May during a brief exchange of gunfire in a disputed border area. The two Southeast Asian neighbours have contested sovereignty over various undemarcated points along their 817km land border for over a century.
