BANGKOK, Dec 14 - Thailand's military said it was considering blocking fuel exports to Cambodia, as fighting between the two countries spread to coastal areas of a disputed border region two days after U.S. President Donald Trump said the sides had agreed to a new ceasefire.

The Southeast Asian neighbours have resorted to ‍arms ​several times this year since a Cambodian soldier was killed in a May skirmish, reigniting ‍a conflict that has displaced hundreds of thousands of people on both sides of the border.
