Cambodia’s powerful former leader Hun Sen and Thailand’s prime minister have made separate visits to border areas

The reescalation of conflict was sparked on May 28, when a Cambodian soldier was killed in an early morning clash between both nations’ troops, in an area called the Emerald Triangle—the shared border between Thailand, Cambodia, and Laos. The area remains disputed as both Thailand and Cambodia lay claims to parts of the region.

The leaders of Thailand and Cambodia are visiting different parts of their disputed land border on Thursday as tensions between the two neighbours simmer over a territorial dispute and the Thai government teeters on the brink of collapse.
