Jakarta, CNN Indonesia --

Thailand's military said it was considering halting fuel exports to Cambodia as fighting between the two countries spread to coastal areas along their disputed border. The clashes came two days after US President Donald Trump said the two sides had agreed to a new ceasefire.

The two Southeast Asian neighbors have been at war several times since a Cambodian soldier was killed in a clash in May. The incident reignited a conflict that has displaced hundreds of thousands of people on both sides of the border.

Thailand's military commanders have discussed blocking fuel exports to Cambodia, including asking the navy to be wary of ships carrying strategic supplies and designating maritime zones near Cambodian ports as"high risk."

"There are currently no orders regarding these measures," said Captain Nara Khunkothom, assistant spokesman for the Royal Thai Navy, as reported by Reuters, Sunday (14/12).

He added that the issue would be discussed at a security meeting on Monday.

Thailand's Energy Ministry said on Friday that it had halted oil exports to Cambodia since June. According to Energy Ministry data, Thailand exported 2.2 billion liters of fuel to Cambodia last year.

Attack each other

Cambodia has accused Thailand of attacking civilian infrastructure, including the use of fighter jets and shelling civilian areas. Thailand says it only targets military targets.

Thailand declared a curfew in southeastern Trat province on Sunday as fighting continued along the two countries' 817-km border.

A soldier and a civilian were killed by a BM-21 rocket fired by Cambodia on Sunday, Thai authorities said.

At least 16 soldiers and 10 civilians have been killed and hundreds more injured since the latest clashes began on Monday with 258,626 civilians displaced, according to Thai authorities.

Cambodia reported no new deaths or injuries on Sunday. According to the Cambodian Ministry of Interior, at least 11 people have been killed, 74 injured, and 394,706 displaced since Monday.

Thai troops said Saturday they had destroyed a bridge used by Cambodia to transport heavy weapons and other equipment into the region and launched an operation targeting artillery in Cambodia's coastal province of Koh Kong.

"Overall, there have been continuous clashes" since Cambodia reaffirmed its openness to a ceasefire on Saturday, Thai Defense Ministry spokesman Rear Admiral Surasant Kongsiri told a news conference in Bangkok on Sunday.
