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

Thailand's prime minister and Cambodia's influential former premier are visiting different parts of their disputed land border on Thursday as tensions simmer between the two neighbours over a territorial dispute and the Thai government teeters on the brink of collapse.

The fate of Thailand’s prime minister, Paetongtarn Shinawatra, is hanging in the balance after only ten months in office. A recent flare-up in a historical border conflict between Cambodia and Thailand could become her ultimate undoing.
