You’ve seen the photos of Russian warships docking in Havana harbor, gray steel against the turquoise Caribbean. It looks like a 1962 rerun. But honestly, if you think the Cuba and Russia relationship is just a Cold War sequel, you’re missing the actual story. It’s way more complicated than just missiles and cigars now.
Basically, Havana is broke and Moscow is isolated. That’s a powerful glue.
In early 2026, the vibe in Havana is tense. The economy contracted by over 4% last year. People are dealing with "wartime economy" measures—Joaquín Alonso, the Minister of Economy, basically told the National Assembly that things are going to stay rough. So, when Vladimir Putin signs a massive military cooperation pact, like he did in late 2025, it’s not just about ego. It’s about survival for one and leverage for the other.
The 2025 Military Pact: More Than Just Posturing?
Last October, Russia’s Federation Council ratified a new intergovernmental agreement on military cooperation. It sounds scary. On paper, it’s a "strategic framework" to strengthen defense ties.
But what does that actually mean on the ground?

There’s a lot of talk about "protecting Russian interests" and establishing legal bases for future accords. Some analysts, like those at Chatham House, suggest this is a psychological signal to Washington. If the U.S. keeps pushing in Ukraine, Russia pushes back in the Caribbean. It’s a classic move. But let's be real: there are no nuclear missiles moving into the Sierra Maestra right now. Instead, we’re seeing "symbolic reciprocity." Russia sends a frigate; Cuba sends a diplomatic "thank you" by backing Russia’s narrative on NATO expansion.
Kinda makes you wonder who’s getting the better deal.
Money, Power, and "Science Fiction" Investments
Russia has pledged to dump over $1 billion into Cuba by 2030. Deputy Prime Minister Dmitry Chernyshenko has been touting this "Plan 2030" everywhere. They’re looking at:
- Modernizing old Soviet-era steel mills and sugar plants.
- Building a logistics hub at the Port of Mariel (about 40km west of Havana).
- Fixing the crumbling energy grid with new thermal power units.
- "Smart hotels" where AI and digitization supposedly make up for a lack of staff.
Here’s the catch. At the St. Petersburg International Economic Forum (SPIEF) in 2025, some Russian delegates were a bit more blunt. One official literally said he hoped the plans were "real and not science fiction."

Why? Because Cuba owes a lot of money. They’re a "reliable partner" politically, but a nightmare for an accountant. Russian banks are only stepping in because the Russian government is subsidizing the interest rates. Without that, no sane businessman would touch these projects.
The Ukraine Factor: A New Kind of Debt
You might have heard the rumors about Cubans fighting in Ukraine. It’s not just a rumor. Estimates suggest thousands of Cubans have ended up on the front lines. Havana officially says they hate "mercenarism" and even busted a trafficking ring in 2023, but the flow of people hasn't totally stopped.
It’s a grim exchange. Cuba gets shipments of oil—roughly 1.64 million tons a year—and Russia gets bodies and a loyal vote in international forums. In 2025, Miguel Díaz-Canel was right there in Red Square for the 80th anniversary of Victory Day. He wasn't just there for the parade. He was there to ensure the lights stay on in Havana.
Why This Matters for 2026 and Beyond
The Cuba and Russia relationship is shifting into a "multipolar" strategy. Cuba officially joined BRICS as a partner recently. They’re trying to move away from the U.S. dollar, using the Mir card system so Russian tourists can spend rubles at Varadero beaches.

Actually, the tourists are a huge deal. In 2024, a record 186,000 Russians visited the island. Moscow wants to become the #1 source of tourists for Cuba. If you walk through Old Havana today, you’re as likely to hear Russian as you are Spanish or English.
But the relationship has limits. Russia is busy. The war in Ukraine is expensive and draining. While they want a "logistics hub" in the Gulf of Mexico, they don't have the endless pockets the Soviet Union once had.
Actionable Insights for Following This Trend:
- Watch the Port of Mariel: If the Russian logistics hub actually breaks ground with heavy machinery, the "science fiction" is becoming reality. This is the best indicator of long-term Russian commitment.
- Monitor the Mir Card Expansion: The more Cuba integrates with Russian financial systems, the less impact U.S. banking sanctions have on day-to-day tourism and small business.
- Follow BRICS Developments: As a partner nation, Cuba’s role in "de-dollarization" will be a bellwether for how other Latin American countries might lean if the U.S. doesn't change its regional policy.
- Energy Grid Stability: Russia promised to fix the power plants. If the blackouts in Havana continue through 2026, it means the $1 billion investment plan is stalling.
The bond between these two is built on a shared "animosity" toward U.S. hegemony. As long as the embargo stays and the war in Ukraine continues, Havana and Moscow will keep dancing. It’s a marriage of convenience, maybe, but neither side is looking for a divorce anytime soon.
