All relevant agencies, including the Ministry of Defense, the Ministry of Foreign Affairs, and the National Security Council, have worked in unified operations to resolve the Thailand-Cambodia border situation. The main objective is to seek a peaceful solution to the issue for the benefit of the people of both countries and for ASEAN as a whole.

Deputy Minister of Defense General Nattaphon Narkphanit on 10 June 2025 summarized details of the joint operations after the Cabinet meeting on 10 June 2025 at Government House. He said that all relevant agencies have been working closely together since 28 May 2025, following a border clash between Thai and Cambodian troops.

On 5 June, he said, Deputy Prime Minister and Minister of Defense Phumtham Wechayachai met the Cambodian Deputy Prime Minister and Minister of National Defense in Aranyaprathet District, Sa Kaeo Province, to exchange views concerning the border situation. Thailand stressed the need to reduce the level of tension and avoid any confrontation between troops in the area of Chong Bok, Ubon Ratchathani Province.

The Cambodian side wanted to bring the border issue to the International Court of Justice (ICJ), while Thailand reaffirmed its intention to use bilateral mechanisms to find a peaceful solution, especially the Thailand-Cambodia Joint Boundary Commission (JBC). Thailand also proposed troop redeployment in order to reduce confrontation.

On 6 June, Mr. Phumtham held a meeting of the National Security Council at the instruction of the Prime Minister, who also attended the meeting to discuss guidance to resolve the border situation. The meeting proposed the closure of some border crossings and the use of control measures. It was of the view that the control measures were needed, as the movement of Cambodian troops to the border area might lead to unwanted incidents affecting the security and safety of the people living along the border. 

Concerned over the people who need crossings for trading, working, education, and medical services, the Thai government decided not to close all border checkpoints immediately. Instead, the procedure is divided into four steps depending on the circumstances in specific areas. These steps include (1) limits on crossings, (2) reduction of the time periods for crossings, (3) closure of certain checkpoints, if necessary, and (4) should the situation escalate to crisis-level, all checkpoints along the border may be closed, to allow for the highest levels of control. The meeting of the National Security Council approved these four steps.

Also, on 6 June, the Cambodian side rejected the proposal by Thailand for troop redeployment. The Prime Minister, therefore, instructed relevant agencies to implement step 1 (limits on crossings) and step 2 (reduction of the time periods for crossings) at the same time, in accordance with the decision of the National Security Council.

Concerning the announcement of martial law in parts of Chanthaburi Province to control the border situation, as reported in some media, General Nattaphon explained that, in fact, martial law is already in effect in all border districts across the country, and that the military is able to act in accordance with the law. However, the National Security Council was of the view that, in the present era, it is not appropriate to enforce martial law.
