BANGKOK/PHNOM PENH (Reuters) -Cambodia's Defence Ministry confirmed on Sunday that Thailand and Cambodia had agreed to return their troops to previous border positions after a clash in which a Cambodian soldier was killed prompted both to reinforce their military presence.

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 shortened operating hours at 10 border crossings with Cambodia, citing security concerns, as tensions between the two countries simmered after a deadly clash last month. A day earlier, both the Southeast Asian countries reinforced their military presence along disputed border areas,
