Thailand and Cambodia have reached an agreement to withdraw their troops to their original positions in a disputed border area.

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 imposed severe restrictions along its 817km border with Cambodia as both sides continue to deploy troops around the Emerald Triangle while talks have yielded little results as Phnom Penh pushes the dispute into an international court.
