The Tatmadaw is mounting a campaign to restore its grip on the Kalay–Tamu trade passage, a strategic land link between Myanmar and India that has been under the control of People's Defence Force groups for the past two years.

Since 2024, PDF units have maintained a stranglehold on the corridor, extracting tolls from commercial traffic, intimidating travellers, destroying infrastructure and confiscating cargo. This blockade has devastated the local economy, triggering acute shortages of food and basic goods while inflation has driven up prices in nearby communities. The situation has also ravaged public services, with residents struggling to reach hospitals and schoolchildren missing classes as movement across the region has become increasingly dangerous.

On June 7, 2026, the Tatmadaw initiated a coordinated push to clear the route, with military units advancing from both Kalay and Tamu simultaneously. The force moving from Tamu has advanced to near Yan Lin Phai Village, while troops from Kalay have reached the vicinity of Ngar Mile Village. Initial reconnaissance has uncovered extensive damage to critical infrastructure, including the Nanmutta Bridge and the 55-Mile Bridge, both reportedly destroyed by PDF units. Villages throughout the area have been fortified with trenches, bunkers and other defensive installations.

The military campaign is also tasked with removing landmines scattered along the roadway and reconstructing bridges and other damaged facilities. Officials have indicated that reopening the passage remains a priority, with authorities optimistic about achieving access restoration in the coming weeks.

The Kalay–Tamu corridor ranks among Myanmar's most strategically vital transportation arteries, connecting the country's northwest region with India and serving as a crucial artery for cross-border commerce. Beyond trade, the route underpins regional mobility, healthcare access and education provision for communities in both nations.
