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.

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.

BANGKOK (Reuters) -Thailand's military said it is ready to launch a "high-level operation" to counter any violation of its sovereignty, in the strongest words yet in a simmering border dispute with Cambodia that re-erupted with a deadly clash last week.
