Myanmar Junta Loses Key Northern City to Resistance Forces in Biggest Territorial Shift in Two Years

Myanmar's Military Loses Major Northern City in Biggest Blow Since 2021 Coup

It took three weeks of fighting. But on Wednesday, February 26, 2026, the Myanmar military — the Tatmadaw — formally lost control of Lashio, the administrative capital of northern Shan State and the largest city in Myanmar's north, to a combined force of the Three Brotherhood Alliance resistance groups and units of the People's Defence Force, the armed wing of the opposition National Unity Government.

Lashio has a population of approximately 160,000 people and sits at the junction of critical road and trade routes connecting Myanmar to China. Its fall is not merely symbolic. It represents a genuine strategic loss for the junta — control of a major urban center, a functioning military base, and a key node in the supply chain that has sustained Tatmadaw operations in the north.

How the Battle for Lashio Unfolded

The offensive began on February 5 when the Myanmar National Democratic Alliance Army, the Ta'ang National Liberation Army, and the Arakan Army — the three groups comprising the Brotherhood Alliance — launched a coordinated assault on Tatmadaw positions surrounding Lashio from multiple directions simultaneously. The junta's forces, already stretched thin across a country where resistance operations are now active in virtually every state and region, were unable to mount an effective reinforcing response.

The junta deployed airstrikes extensively throughout the battle, including strikes on civilian neighborhoods that human rights monitors documented in real time. Médecins Sans Frontières reported treating 140 civilians with conflict-related injuries at field clinics in Shan State between February 5 and February 24. Satellite imagery showed extensive damage to residential areas of Lashio's eastern districts.

According to David Mathieson, independent analyst on Myanmar affairs based in Southeast Asia, Lashio matters in ways that go well beyond the city itself. The Tatmadaw has now lost a provincial capital to resistance forces. That has not happened since the coup. It breaks a psychological ceiling and demonstrates that the junta cannot hold urban centers if the resistance coordinates effectively.

China's Uncomfortable Position and Regional Implications

China shares a long border with Shan State and has significant economic interests in the region — including pipelines, road infrastructure, and border trade routes that run through areas now contested or controlled by resistance forces. Beijing has maintained an awkward dual posture throughout Myanmar's civil war: nominally neutral while conducting back-channel communications with multiple armed actors and quietly discouraging attacks on Chinese economic assets.

The fall of Lashio puts China in a more difficult position. The Brotherhood Alliance groups that captured the city are not hostile to China — they have generally protected Chinese economic interests in areas they control — but their victory nonetheless represents a shift in the power balance that Beijing did not engineer and does not fully control.

The Association of Southeast Asian Nations, which has been largely paralyzed on Myanmar since the coup, issued a statement calling for all parties to protect civilians and allow humanitarian access. The statement contained no condemnation of either side and no concrete mechanism for action — a reflection of ASEAN's continued inability to respond coherently to what is now one of Asia's most serious ongoing conflicts.

With the junta now controlling less territory than at any point since the 2021 coup, the question of whether Myanmar's military government can survive — and what comes after it if it cannot — is becoming less hypothetical with every passing week.
