Hundreds of Cambodians were seen gathering at the border checkpoint awaiting for border passes from the Thai immigration office to travel to Rong Klua market on the Thai side of the border.
The resumption of border trading followed the closure of the border on Saturday after a group of Cambodian traders rallied at the border to protest against the arrest of 18 Cambodians by Thai police and paramilitary rangers on smuggling charges on August 14.
The Thai authorities found smuggled goods hidden in sacks of second-hand garments brought into the Thai side of the border by the 18 Cambodians.
Later on, Cambodian immigration officials tried to bail out the 18 suspects but this was rejected by the Thai police claiming that the suspects would have to be tried in the court first.
Talk was later held between Sa Kaew governor Pakkarathorn Thienchai and his Cambodian counterpart of Bantey Meanchey. It was reported that the Thai side would withhold the imposition of a new tax system and would not make any more arrests but the 18 detained Cambodians would face trial.
