On August 15, 2025, China, Laos, Myanmar and Thailand held an informal discussion between foreign ministers in Anning, Yunnan. Member of the Political Bureau of the CPC Central Committee and Foreign Minister Wang Yi, Lao Foreign Minister Thongsavanh Phomvihane, Foreign Minister of Myanmar Than Swe, and Thai Foreign Minister Maris Sangiampongsa were present.

Wang Yi said that China, Laos, and Thailand, as friendly neighbors of Myanmar, have a better understanding of Myanmar's unique national conditions and are more eager to see Myanmar restore stability, achieve national reconciliation, hold an open and fair general election, and pursue a development path suited to its national conditions and supported by its people. Since the first quadrilateral meeting last year, the situation in Myanmar has generally stabilized, and efforts are underway to advance post-earthquake reconstruction and safeguard its sovereignty, independence and national stability. Wang Yi called for adhering to a "Myanmar-led, Myanmar-owned" approach, supporting the choices of the Myanmar people, and resolving differences through dialogue. Wang Yi stressed the importance of mediation by ASEAN and assistance from neighboring countries, with ASEAN serving as the main channel, while also giving full play to mechanisms like the Informal Discussion between the Foreign Ministers of China, Laos, Myanmar and Thailand and the Foreign Ministers' Meeting among the Neighboring Countries of Myanmar. He also urged prioritizing people's livelihoods and development, supporting Myanmar in improving people's well-being and post-earthquake reconstruction, and promoting cooperation in various fields for people's benefit, while warning against improper interference by external forces that could undermine regional stability.

The Myanmar side briefed on the domestic situation and preparations for the upcoming general election, stating that since the last meeting, the domestic situation in Myanmar has generally deescalated and stabilized. The Myanmar side expressed gratitude for the support and assistance provided by China, Laos and Thailand, as friendly neighboring countries, in addressing challenges. The Myanmar side reiterated its commitment to advancing domestic peace and reconciliation process through political dialogue, and stated that it is actively preparing for an open and transparent general election at the end of the year to return power to the people.

The Lao side expressed its support for a "Myanmar-led, Myanmar-owned" political process and for Myanmar's general election to achieve peace, stability and national reconciliation.

The Thai side stated that the Myanmar issue is an internal affair of the country, and the international community should respect the choices of the Myanmar people. The general election is an important step in Myanmar's political transition. Thailand is willing to work with other ASEAN countries to provide support and assistance for the smooth progress of Myanmar's general election based on the principle of non-interference in internal affairs.

The four foreign ministers exchanged views on joint efforts to combat cross-border crimes. Wang Yi pointed out that combating cross-border crimes bears on the well-being and safety of the people, represents a common concern of the four countries, and requires coordinated action. Since the last meeting, the four parties have closely cooperated, strengthened border control, and achieved notable results in jointly combating cross-border crimes. However, the regional security situation is still not optimistic, requiring continued coordinated efforts. First, strengthen conceptual guidance and institutional building to implement the Global Security Initiative. Second, strengthen joint operations and border control to block any attempt by lawbreakers to commit cross-border crimes. Third, strengthen capacity building and judicial coordination, and enhance publicity, education, and law enforcement training. Fourth, strengthen transformation development and social governance, coordinate security and development, continuously improve local socioeconomic conditions, and eradicate the breeding ground for illicit and gray industries.

The four parties agreed to continue to strengthen law enforcement and security cooperation, step up efforts to combat cross-border crimes, including online gambling, telecom fraud, drug and weapon trafficking, and human trafficking, and jointly safeguard regional peace and stability.
