Chinese-Backed Training Center Near Vientiane Raises Concerns Over Beijing’s Growing Security Footprint in Southeast Asia

A new Chinese-backed military training facility outside Vientiane is adding to concerns in Southeast Asia that Beijing is steadily expanding its security footprint around Vietnam, complementing its already deepening ties with Cambodia.

The center, located near Laos’ capital, is intended to train Lao security personnel and improve interoperability with Chinese forces, according to regional analysts and local reporting. While Laos has long maintained close political and economic links with China, the addition of a dedicated training hub is being read as another step from infrastructure-heavy cooperation into more overt defense collaboration.

The development comes as Cambodia continues to draw attention for its increasingly visible military relationship with Beijing. In early April 2025, Cambodia officially inaugurated upgrades at Ream Naval Base in Sihanoukville in a ceremony attended by senior Cambodian military officials. The event, covered by the Associated Press, underscored the scale of the base’s redevelopment and the degree of Chinese involvement that has been alleged by Western governments and some regional observers for years.

Together, the Laos training center and Cambodia’s naval-base upgrades feed a broader narrative: that China is building a network of logistical access, training partnerships, and potential dual-use facilities across mainland Southeast Asia. Vietnam sits geographically between China and many of these developments, and it has its own history of tension with Beijing—particularly in the South China Sea, where competing territorial claims have driven repeated stand-offs.

From Beijing’s perspective, closer security ties with neighboring states can be framed as routine cooperation—helping partners professionalize forces, improve disaster response, and strengthen border management. For Laos and Cambodia, Chinese support often comes with equipment, funding, and training that can be difficult to obtain elsewhere, especially for governments facing limited defense budgets and pressure to modernize.

But in Hanoi, the optics are more complicated. Vietnam has pursued a careful strategy of diversifying security relationships—expanding ties with the United States, Japan, India, and Australia—while trying to avoid provoking China. Any perception that Chinese-linked facilities in Laos and Cambodia could one day provide strategic leverage, intelligence advantages, or forward access for Chinese forces is likely to intensify Vietnam’s threat calculations.

Questions about intent remain central. Cambodian officials have repeatedly denied that Ream Naval Base will host an exclusive foreign military presence, insisting the facility is open to friendly navies and serves national defense needs. China has likewise rejected allegations that it is seeking overseas bases in the region, arguing that its activities reflect legitimate bilateral cooperation.

Still, the pattern of incremental steps—training initiatives here, port upgrades there—matters in a region where military access can reshape influence without a formal base agreement. Analysts say the most important signals to watch will be the basing arrangements that follow: who has priority access, what kinds of vessels and aircraft regularly appear, how information-sharing is structured, and whether new facilities expand into intelligence, surveillance, and reconnaissance capabilities.

Why it matters

Vietnam’s security planners, regional navies, and investors watching Southeast Asian stability all have a stake in whether these projects remain limited partnerships or evolve into strategic footholds. Expanded Chinese defense cooperation with Laos and Cambodia could shift the balance of influence on Vietnam’s western and southern flanks and complicate crisis dynamics in the South China Sea. The next key indicators will be transparency around access rights, the pace of new construction, and the frequency and scale of joint training and visits.
