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.

Tension has been rising between Thailand and Cambodia following the killing of a Cambodian soldier on May 28 during a brief exchange of gunfire at a disputed border area between the two Southeast Asian neighbours.

Defence Minister Phumtham Wechayachai issued a statement on Saturday to reaffirm the government's stance against sovereignty violations, saying Thailand will strengthen defence, as Cambodia rejected the withdrawal of troops from the border area after discussions between the two neighbouring countries.
