Vietnam's Leader Frames Asia's Superpower Dilemma in Evolutionary Terms

President To Lam of Vietnam delivered a pointed warning to military leaders gathered from across the Asia-Pacific on 29 May 2026, framing the region's deepening superpower competition in the language of predator and prey. Speaking in Hanoi, To Lam said that "distrust and a lack of respect for established rules" had created conditions in which larger powers treated smaller states as quarry. His formulation—that the international system risks reducing to a culture of "the big fish swallowing the small fish"—represents a notable shift in tone from a Vietnamese leader who has historically balanced carefully between Washington and Beijing.

The speech arrives at a moment when Southeast Asian governments face a genuinely difficult strategic environment. The South China Sea, through which roughly three trillion dollars in trade passes annually, remains the most acute pressure point. Vietnam itself has competing maritime claims with China, and it has sought to deepen security ties with the United States, Japan, and India as a counterweight—without provoking a response from Beijing. To Lam's language suggests that this balancing act is becoming harder to sustain.

The Regional Calculation

What makes To Lam's intervention notable is not the substance—ASEAN capitals have expressed similar concerns privately for years—but the explicitness. Regional forums typically produce communiqués dense with diplomatic qualifications. To Lam's directness reflects a belief, shared across several Southeast Asian foreign ministries, that the ambiguity that once allowed middle powers to navigate between great powers is eroding. When the United States and China negotiate trade terms, technology restrictions, or military deployments, the downstream consequences for states like Vietnam, the Philippines, and Indonesia are not hypothetical. They arrive as supply chain disruptions, as pressure on fishing grounds, as diplomatic phone calls that demand表态.

Vietnam's own position illustrates the bind. It has expanded defence cooperation with Washington, including coast guard training and access to radar systems, while simultaneously maintaining the Communist Party's "bamboo diplomacy"—a framing that emphasises resilience and flexibility rather than alignment. The bamboo metaphor is revealing: it bends but does not break. What To Lam appears to be suggesting is that the wind is now strong enough to test even that flexibility.

Competing Interpretations

The question of what To Lam's warning actually targets is not straightforward. Western analysts will likely read it as a signal of concern about Chinese assertiveness in the South China Sea and along Vietnam's coastline—a reading that aligns with Vietnam's deepening security partnerships with the United States, Japan, and Australia. Under this interpretation, To Lam is signalling discomfort with a regional order in which Beijing's claims increasingly translate into de facto control of maritime space.

But a different reading is possible, and Vietnamese officials do not dismiss it in private: the speech could equally be addressed to Washington. The logic runs as follows. American industrial policy—the CHIPS and Science Act, the Inflation Reduction Act's electric vehicle tax credit provisions, the outbound investment screening regimes now under discussion—has consequences for economies like Vietnam's that have positioned themselves as manufacturing alternatives to China. If the United States is reshaping global supply chains in ways that benefit some middle powers while constraining others, that too constitutes a form of great-power behaviour that smaller states must navigate. To Lam's "big fish" metaphor, under this reading, is deliberately broad enough to cover both.

Vietnamese foreign policy has historically resisted the temptation to resolve strategic ambiguity by choosing sides. The speech should be read in that tradition. It is an insistence that the framework within which Asia's great powers operate must remain one in which small and middle states retain agency—not merely as objects of competition, but as actors with interests that cannot be perpetually subordinated.

Structural Pressures on the Regional Order

The structural forces driving this dynamic are not new, but they are intensifying. American policy under successive administrations has sought to slow Chinese technological advancement through export controls, entity listings, and coalition-building around semiconductor supply chains. China has responded with its own industrial policy: the Made in China 2025 initiative and its successor programmes have funneled state investment into sectors from electric vehicles to advanced manufacturing. The result is a technology decoupling that does not respect national borders. Countries in Southeast Asia, many of which host factories operated by both American and Chinese firms, find themselves increasingly pressed to demonstrate loyalty to one camp or the other—or to accept that their economic integration into both systems carries political risk.

The South China Sea remains the most visible theatre, but it is not the only one. The Taiwan Strait, the East China Sea, the disputed border regions between India and China—each represents a potential flashpoint where the interests of great powers collide, and where smaller states bear a disproportionate share of the consequences when they do. ASEAN's formal position—that the region must remain open, stable, and governed by rules all parties accept—has not changed. The practical question is whether that position remains tenable as the space between the great powers narrows.

China's official position, as articulated through the Ministry of Foreign Affairs and state media, has consistently argued that its regional behaviour is defensive and rule-abiding—that Chinese sovereignty claims in the South China Sea are historical and legal, not expansionist. Beijing has also pointed to its economic integration with Southeast Asia, noting that China is the largest trading partner for most ASEAN members. The argument, made in forums like the China-ASEAN dialogue and in bilateral exchanges, is that economic interdependence provides its own stabilising logic. Whether that argument persuades capitals that have experienced Chinese maritime enforcement actions at close quarters is a separate question.

What Comes Next

The immediate stakes are practical. Vietnam, the Philippines, Malaysia, and Indonesia are all managing their own territorial disputes with China while maintaining economic relationships that make confrontation costly. The United States has made clear that it regards a free and open Indo-Pacific as a core interest, but the specifics of what that commitment means in a crisis—particularly one involving maritime incidents below the threshold of armed conflict—remain deliberately undefined. That ambiguity serves American interests in some respects, but it leaves regional partners uncertain about what backup, if any, they can expect.

For now, the bamboo stands. But To Lam's speech suggests that the capitals watching the most closely are those calculating whether the international environment has shifted permanently—and whether the diplomatic flexibility that has served ASEAN so well for three decades may be approaching its limits. The big fish, as the saying goes, do not negotiate with the small ones. Whether that proposition holds will define the next chapter of Asian security.

This publication's Asia desk has covered Vietnam's diplomatic positioning since 2022, tracking the evolution from cautious neutrality toward what Hanoi now openly describes as "active international integration." The wire framed To Lam's speech as a warning about great-power rivalry; this article expands the counterpoint to suggest the warning is directed at more than one audience.
