Cambodia has agreed to attend a General Border Committee meeting with Thailand in Indonesia on Mar 24-25, Foreign Ministry spokesman Thani Thongphakdi said on Wednesday.
The GBC is co-chaired by defence ministers of the two countries.
Mr Thani said that on this occasion Thailand could consult with Cambodia over the terms for Indonesia to send observers to the Thai-Cambodian border.
A source at the Thai Armed Forces Command said the Border Affairs Department had sent a letter to notify Defence Minister Prawit Wongsuwon about the meeting, which has been set to be held in Bogor, Indonesia.
If all sides agree to attend the meeting as proposed by Indonesia, it would be the first GBC meeting to be held in a third country, the source said.
Gen Prawit last week called Cambodian counterpart Gen Tea Banh on the telephone asking him to move forward from April to March the 8th GBC meeting which was originally to be hosted by Cambodia in Siem Reap.
"But Gen Tea Banh has not yet replied. This is because Cambodian Prime Minister Hun Sen does not want the meeting to be held bilaterally," the source said.
The source said the Thai side in fact wants the GBC to be a forum for military leaders of the two countries to meet and talk without the presence of a third person.
However, since Cambodia and the Foreign Ministry have agreed to the proposal from Indonesia, the Thai military is expected to also agree, the source said.
