Deputy Finance Minister Pruetichai Damrongrat told reporters that the No 68 road will link Chong Chom checkpoint in Surin province to Cambodia.
Meanwhile Deputy Prime Minister Suthep Thaugsuban said that the cabinet will not consider an financial assistance of Bt31 million to Cambodia in its meeting next week.
The proposal is put on hold as a measure of Thailand to protest Cambodia.
In a separate interview, Abhisit said he was considering further measures against Cambodia, but vowed that his government would not seal off checkpoints on the border and said that the rift with Phnom Pen would not lead to violence.
"I don't want the situation going out of control," he said.
