Thailand's foreign ministry said on Friday it was taken aback by an unprecedented public attack on the Thai premier and her family by Cambodia's influential former leader, but stressed the need for diplomacy to resolve an escalating bilateral dispute.

The General Department of Immigration (GDI) has announced that it will not permit any type of cargo transport to enter, exit, or transit through any international border checkpoints or regional checkpoints along the Cambodian-Thai border.

Cambodia’s most influential politician called for a leadership change in Thailand, citing doubts about the prime minister’s ability to manage a border dispute between the two countries.
