China's New Laos Military Base Signals Expanding Southeast Asia Foothold

China has quietly opened a military training facility in Laos that signals something larger than pilot instruction. The Joint Support and Training Center at Ban Keun Airport, located north of Vientiane, began formal operations last month alongside a new aviation academy. Beijing frames it as a joint venture to train Lao air force pilots—a modest, cooperative endeavor. But analysts across the region are reading it as a strategic foothold that could reshape the military balance in mainland Southeast Asia.

The facility represents China's first dedicated air force presence overseas, a gap that has long constrained Beijing's ability to project power across the Indo-Pacific. Until now, China maintained only two foreign military installations: a base in Djibouti since 2017, and expanded access to Cambodia's Ream Naval Base, which was formally inaugurated last year. Ban Keun fills a different kind of void. It gives the Chinese military a location on the mainland, positioned to train personnel, maintain equipment, and potentially stockpile supplies in a region where the United States still dominates through alliances with the Philippines, Japan, and Australia.

What makes Ban Keun particularly significant is not what it is today, but what it could become. Hunter Marston, director of the Southeast Asia Program at Australia's Lowy Institute, told analysts that the facility's infrastructure provides Beijing with options for expansion. The political conditions are favorable too. Laos has become deeply dependent on Chinese capital over the past two decades—so dependent that the International Monetary Fund estimates the country's public debt at roughly 81 percent of GDP, with China as the largest bilateral creditor by a wide margin. In 2020, China's state-owned power company acquired a 90 percent stake in the company that operates most of Laos' electricity transmission network. This financial leverage gives Beijing considerable room to demand expanded military access if it chooses to do so.

The development carries particular weight for Vietnam, which has long viewed Laos and Cambodia as strategic buffers protecting its western border. Hanoi and Beijing maintain economic ties and party-to-party relations, but they remain locked in competition over the South China Sea, where their territorial claims have repeatedly sparked tension. A more permanent Chinese military presence in Laos threatens to complicate Vietnam's defense planning by potentially positioning Chinese forces on its flank. Euan Graham, a senior fellow at the Australian Strategic Policy Institute, described the scenario as an "alarming possibility of strategic encirclement." For decades, Vietnam worked to maintain considerable political and military influence across the Indochinese peninsula. Now it faces the prospect of Chinese military infrastructure taking root in what it has traditionally considered its sphere of influence.

Yet some analysts urge caution about overstating Ban Keun's immediate military value. Collin Koh, a senior fellow at Singapore's Nanyang Technological University, notes that geography imposes real constraints. Laos is landlocked, which means Ban Keun offers no sea access—a significant limitation compared to Ream. Chinese military aircraft already operate from larger, better-equipped bases in southern China, so the facility does not immediately give Beijing a major operational advantage for projecting power into the South China Sea. The site could gradually accumulate more personnel, training aircraft, and eventually more advanced equipment, but its usefulness remains bounded by its location.

Laos itself has maintained a formal policy of non-alignment since 1986, a balancing act it has preserved despite close relations with Vietnam, China, and Russia. Simon Creak, a historian of Laos at Singapore's National Institute of Education, noted that the country has historically resisted hosting foreign military bases—a sensitivity rooted in memories of CIA operations during the Indochina Wars. He considers it "highly unlikely" that Laos will abandon its effort to balance relations among its larger neighbors, even as it deepens military cooperation with Beijing. The facility at Ban Keun may represent something less than a permanent Chinese base and something more than a training center—a middle ground that allows Laos to deepen ties with China while maintaining the appearance of strategic independence. What remains unclear is whether that balance can hold as China's military footprint in the region continues to expand.
