Indonesia said yesterday that it was still waiting for approval from Thailand and Cambodia before dispatching teams of military observers to the countries’ contentious border, where four days of fighting last month left at least 10 people dead and dozens injured.

At a meeting of foreign ministers of the Association of Southeast Asian Nations in Indonesia in February that followed the clashes, Cambodia and Thailand agreed to accept the observers in order to help preserve the fragile peace along the border near Preah Vihear temple. While Cambodia has already approved the terms of reference outlining the observers’ mission, Thailand has yet to do so.

“We’re still waiting for further approvals from both countries before we can proceed to go to the area,” Indonesia foreign ministry spokeswoman Kusuma Habir said yesterday, according to Agence-France Presse. “We hope that we will receive their approvals as soon as possible.”

Thailand and Cambodia are also scheduled to hold talks in Indonesia on April 7-8 in relation to the border dispute. Earlier this week, however, the Bangkok Post reported that Thai Army Chief Prayuth Chan-ocha and defence minister Prawit Wongsuwon had said they would not attend the talks because they did not believe a third country should be involved.
