- To Lam at the 2026 Shangri-La Dialogue pledged Vietnam would not seek to be a 'center of power' in Southeast Asia, reaffirming Hanoi's Four Nos policy — no military alliances, no siding against any country, no foreign bases on Vietnamese soil, and no use or threat of force.
- Vietnam shares a 3,400-kilometer border with Laos and Cambodia and has 103 million people, roughly four times their combined populations, making friendly governments in Vientiane and Phnom Penh essential to its western security against hostile great powers.
- Hanoi toppled the Khmer Rouge in December 1978 and installed a pro-Vietnamese government, stationing 50,000 troops in Laos and 200,000 in Cambodia to neutralize Chinese influence — a posture that drew Western, ASEAN, and Chinese condemnation as regional hegemony and forced retrenchment after 1988-89.
- Vietnam now relies on the 1977 Vietnam-Laos Treaty of Friendship and Cooperation, support for the Hun family in Cambodia, and the 1993 Cambodian constitutional ban on foreign bases — commitments also binding China, the U.S., and France under the 1991 Paris Peace Agreements.
- Vietnam is countering China's expanding presence at Cambodia's Ream Naval Base through its own infrastructure push in Laos and Cambodia, the article's framing of an 'infrastructure war' against Beijing in western Indochina.
Why it matters: To Lam's renunciation of 'center of power' status masks a deeply practical contest: with China expanding at Ream Naval Base and a 3,400-km border to defend, Vietnam's pivot from 200,000 occupation troops to treaty-based influence and infrastructure competition is Hanoi's only affordable counter to Beijing's western push without its old Soviet patron.
