The deployment signals the urgency around a flagship project that has already slipped past its original 2025 opening date.

Hundreds of officers and enlisted soldiers have been brought onto the site in Dong Nai City in the country's south to reinforce a civilian workforce that has struggled to keep pace with one of Southeast Asia's biggest construction projects.

The move was confirmed during a June 13 inspection by Construction Minister Tran Hong Minh, who was told by an Airports Corporation of Vietnam (ACV) representative that more than 76% of the total project value had been completed.

The workforce has been topped up in recent weeks but still falls nearly 2,000 short of the roughly 9,000 workers the site needs, with several units calling in military personnel to bridge the gap.

The labor crunch reflects a wider squeeze in southern Vietnam, where a cluster of megaprojects is competing for the same pool of skilled construction workers.
