Cuba, China, and the Limits of the Containment Doctrine

Secretary of State Marco Rubio has reframed Cuba as an acute national security concern. Cuba hosts Russian and Chinese intelligence assets on the island, he told reporters on 21 May 2026, and that presence — combined with the island's proximity to American shores — constitutes a threat requiring the full range of presidential options, including potential military action. "Ebola is in Africa. Cuba is 90 miles from our shore," Rubio said, drawing a parallel designed to stress urgency over geography.
The framing is structurally coherent. Cuba is indeed 90 miles from Florida. A hostile intelligence footprint that close to American territory is not a comfortable reality. But the framing also contains a logical sleight of hand: proximity does not equal dependency, and dependency is the actual metric that has historically determined whether a small-state presence near a great power becomes a strategic liability.
Cuba is not a Chinese forward base. It is a client state with leverage — leverage that derives precisely from its location within an American sphere of influence that Washington has spent decades trying to shrink. The island's value to Beijing lies not in what it can do to America, but in what it can do to American credibility in a region that has been, by doctrine, a US preserve. That is the structural reality Rubio's rhetoric flattens.
The Containment Trap
The problem with Rubio's framework is not the diagnosis. It is the prescription. "The president always has the option to do whatever it takes to support and protect the national security of the United States" — that formulation sounds robust. It is, in practice, an invitation to repeat a policy that has produced diminishing returns for six decades.
American policy toward Cuba has been defined by isolation since 1961. The embargo, the travel restrictions, the designation as a state sponsor of terrorism — these measures were designed to strangle the Castro government into democratic reform. Instead, they have produced a stagnant economy, a diaspora that has fractured along political lines, and a government that has survived by swapping one patron for another. The Soviet subsidy era ended. Russian diplomatic and commercial engagement filled part of that vacuum. Chinese infrastructure investment — ports, cables, agricultural partnerships — followed. The pattern is not ideological. It is structural: a desperate economy opens itself to whoever offers capital without conditions.
Rubio's implied remedy — more pressure, more visibility, more military signaling — would accelerate the very dynamic he is trying to reverse. Chinese and Russian presence deepens when American presence retreats. It is not clear why the third iteration of the same strategy should produce a different outcome.
Beijing's Calculus, Plainly
Beijing's interest in the Caribbean is not analogous to Cold War containment theory, and treating it as such produces bad policy. China is not seeking a military foothold in Cuba — not in the traditional sense that phrase implies. It is building infrastructure, acquiring port access, and creating diplomatic leverage through investment rather than occupation. The 2019 agreement to route an undersea internet cable through Cuba, and ongoing discussions about expanded satellite and port infrastructure, are consistent with a broader Chinese strategy of embedding itself in Latin American and Caribbean economies through commercial ties that come with political obligations attached.
This is not containment in reverse. It is the same playbook Beijing has deployed across the Global South — from port deals in the Eastern Mediterranean to railway concessions in East Africa. China builds infrastructure where others will not, and collects geopolitical goodwill as a byproduct. Washington finds this threatening because it erodes the unipolar assumptions that have governed the hemisphere since the Monroe Doctrine. But the threat is not military in any near-term sense. It is structural: a region that finds Chinese capital more reliable than American goodwill will align accordingly.
Rubio is right that this represents a challenge. He is less clear about what a constructive American response looks like. The US cannot out-invest China in the Caribbean — not at the scale required to offset decades of infrastructure deficits and political indifference. What it can do is offer an alternative. That alternative has, historically, involved engagement rather than isolation. The normalised diplomatic relations that briefly existed under the Obama administration were not an act of generosity toward Havana. They were a recognition that the embargo had failed its own objectives and that the only lever worth pulling was a different one.
Migration as Symptom, Not Security
The migratory dimension of Rubio's framing deserves separate examination. The secretary linked the Chinese and Russian footprint directly to the "migratory crisis" that proximity to Cuba creates. Cubans attempting to reach American shores by sea and via Central American land routes represent a genuine policy challenge — one that the United States has struggled to address through enforcement alone.
The problem is that migration is a symptom of economic failure, not a security threat in the conventional sense. Cubans leave because the domestic situation is untenable. Tighter sanctions will not reduce that pressure; they will intensify it. A Havana that is more isolated, more financially constrained, and more dependent on external patronage will produce more departures, not fewer. The refugee corridors that Rubio identifies as a national security concern are, in significant part, downstream of the policy he is defending.
This is not an argument that the Cuban government's behaviour is acceptable. It is an observation that the policy instrument being proposed has a documented track record of aggravating the problem it is designed to solve. A hemispheric policy that addresses the conditions driving migration — economic development, institutional reform supported by engagement rather than embargo — would do more to address the security dimension Rubio raises than the full weight of American coercive pressure.
What the Doctrine Misses
The stakes are concrete. If the United States continues to treat Cuba as a containment problem rather than a development challenge, the likely trajectory is clear: Chinese and Russian presence deepens as American influence contracts, the island becomes a permanent feature of a contested Caribbean, and the hemisphere's southern tier continues its drift toward whoever offers infrastructure and investment rather than sanctions and ideology. The alternative is not naïve engagement — it is strategic recognition that a client state held under permanent pressure will seek relief from whoever offers it. That is not a failure of Cuban character. It is a structural outcome of American policy choices.
Rubio's alarm is legitimate. The alarm is not, however, an argument for the prescription he implies. The doctrine he invokes has run for sixty years and produced the opposite of its stated objective at every turn. The question the United States should be asking is not whether to pressure Cuba harder — it is whether to continue pursuing a strategy that has, at each iteration, produced the conditions it claims to be addressing. The Chinese presence in Cuba is not destiny. It is the result of choices — Cuban choices, Beijing's choices, and American choices. Of those three, only the last one is within Washington's direct control.
