Preliminary talks between Thailand and Cambodia defense officials started on Monday in Malaysia ahead of a key ministerial level meeting on Thursday, as a fragile truce continues to hold a week after the two sides agreed on a ceasefire.

The situation on the border between Cambodia and Thailand remains “sensitive and tense” as talks between the sides continued in Kuala Lumpur, Malaysian Prime Minister Anwar Ibrahim said Tuesday, adding that a decision on sending a military presence from the regional bloc will be made later.
