A ceasefire was established on December 27, 2025, but the border crossing situation has not changed: all checkpoints including the heavily used Poipet-Aranyaprathet crossing remain shut. The Australian, US, UK, and Canadian governments all advise against travel within 50 kilometers of the Thailand-Cambodia land border.
