In Vietnam, since withdrawing its military occupation forces from Cambodia in the late 1980s and the end of Soviet aid in 1991, Vietnam has practiced a non-aligned foreign policy and security doctrine known as the "Four Nos" (no alliances, no siding with one country against another, no foreign bases, and no using force in international relations); despite longstanding tensions with Beijing over maritime boundaries in the South China Sea, Vietnam puts a priority on stable relations with China, given its proximity, size, and status as Vietnam's largest trading partner

the responsibilities of the People's Army of Vietnam (PAVN) include protecting the country's independence, sovereignty, territorial integrity, and national interests, as well as assisting civilian authorities with natural disasters; in recent years, the PAVN has placed additional emphasis on protecting Vietnam's interests in the disputed South China Sea; the military is also involved in economic projects, such as electrical infrastructure, oil and gas services, hydroelectric projects, aviation and seaport services, telecommunications, and the shipbuilding industry, while military-owned factories and enterprises produce weapons and equipment (2025)
