Myanmar’s military authorities have ordered Timor-Leste’s senior diplomatic representative to leave the country, escalating tensions after reports that Dili had initiated legal proceedings accusing Myanmar’s ruling generals of international crimes.
In a statement Myanmar’s junta said it had summoned Timor-Leste’s chargé d’affaires and informed the envoy that his presence was no longer acceptable.
The move followed public disclosures by the Chin Human Rights Organization (CHRO) that prosecutors in Timor-Leste were examining allegations of war crimes and crimes against humanity committed by Myanmar’s military.
The diplomatic rupture underscores widening divisions within the Association of Southeast Asian Nations (ASEAN) over how to respond to Myanmar’s prolonged political and humanitarian crisis since the armed forces seized power in February 2021.
The coup ousted an elected civilian government and triggered nationwide unrest, armed resistance and intensified conflict across several regions.
Myanmar’s military government described the reported legal initiative as a “great disappointment,” accusing Timor-Leste of breaching ASEAN principles that emphasize sovereignty and non-interference in members’ internal affairs.
The junta said the appointment of a foreign prosecutor to examine allegations against its leadership ran counter to those commitments.

Timor-Leste’s government has not publicly detailed the scope of any investigation, and officials in Dili have not immediately responded to the expulsion announcement.
The CHRO said earlier this month that a senior Timorese prosecutor had been assigned to review evidence submitted by the group under the doctrine of universal jurisdiction, a legal principle allowing national courts to pursue serious international crimes regardless of where they occurred.
According to the rights organization, its filing contains documentation alleging abuses against civilians in Myanmar’s western Chin State, including gang rape, the killing of religious figures, a massacre of 10 people and an air strike on a hospital.
Reuters and other international media have not independently verified those claims.
Myanmar’s military has repeatedly rejected accusations of systematic abuses, saying its operations target what it calls “terrorists” opposing state authority.
The legal effort would add to mounting international scrutiny faced by Myanmar’s generals.
The country is already defending itself before the International Court of Justice over allegations that security forces committed genocide against the mostly Muslim Rohingya population during military operations in 2017 that drove hundreds of thousands into neighboring Bangladesh.
Myanmar denies genocidal intent, arguing its actions were legitimate counterinsurgency measures.
The expulsion marks the second diplomatic confrontation between the two countries in recent years.
In August 2023, Myanmar ordered Timor-Leste’s top diplomat to depart after officials from Dili met representatives of Myanmar’s shadow National Unity Government, an opposition administration formed by lawmakers and activists removed from power following the coup and outlawed by the junta.

Timor-Leste became ASEAN’s 11th member in October 2025 after years as an observer, joining a bloc that has struggled to formulate a unified response to Myanmar’s crisis. ASEAN leaders agreed in 2021 on a “Five-Point Consensus” calling for dialogue, cessation of violence and humanitarian access, but implementation has stalled, and the junta has continued military operations across multiple regions.
Analysts say the latest dispute reflects contrasting approaches within ASEAN toward accountability and engagement.
Susannah Patton of the Lowy Institute said it was uncommon for one ASEAN member to pursue legal action against another, highlighting Timor-Leste’s willingness to prioritize human rights principles even at the risk of diplomatic friction.
“It is quite unusual” for an ASEAN state to take such a step, Patton said, adding that Timor-Leste’s position places it at one end of a spectrum within the bloc regarding how firmly members should pursue accountability measures against Myanmar’s military leadership.
ASEAN governments have adopted differing strategies since the coup, ranging from continued engagement with Myanmar’s authorities to restrictions on junta participation in high-level meetings.
Several member states have argued that isolating the military could worsen instability, while others have pressed for stronger measures in response to ongoing violence and humanitarian concerns.
Patton said the legal initiative was unlikely to prompt a fundamental shift in ASEAN’s collective policy but could intensify debates within the organization over its consensus-based decision-making model. “Timor-Leste is now going to represent one extreme end of that spectrum,” she said, referring to calls for stronger international action.
Myanmar has remained diplomatically isolated in parts of the international community since the coup, facing sanctions from Western governments and criticism from United Nations investigators who have documented alleged abuses against civilians.
The military leadership maintains that foreign pressure interferes with domestic affairs and insists it is preparing for elections, though critics and opposition groups have dismissed those plans as lacking credibility.
The immediate consequence of the dispute will be the departure of Timor-Leste’s senior envoy from Yangon, further reducing formal diplomatic engagement between the countries.
It remains unclear whether Timor-Leste will proceed publicly with any prosecution or how Myanmar might respond beyond the expulsion order.
The junta said the diplomat had been given one week to leave the country, setting a near-term deadline that could determine whether tensions ease through quiet diplomacy or deepen into a broader rift within ASEAN as legal proceedings develop.
