U.S. Ties Cuba Talks to Political Change After UN Clash
U.S. Secretary of State Marco Rubio said on September 23, 2026, in New York City that Washington is prepared to help Cuba move toward political transition if Havana is open to changing its government. Al Jazeera
By transition he meant a shift away from Cuba's current communist system.
What happened at the UN
The offer followed a confrontation at the United Nations a day earlier. On September 22, President Donald Trump called Cuba a "failed state" in his address to the UN General Assembly. The Cuban delegation walked out. Trump said his administration seeks fundamental change in Cuba and that the communist regime is under great pressure. He also said the United States was willing to use military power against Cuba when necessary.
Trump used the same address to defend military action against Iran and Venezuela, according to UN coverage of the speech. UN News The Assembly's General Debate was scheduled for September 22-28.
Rubio conditioned any engagement on a break with the current system. He said Washington would work with some Cuban leaders whose "hands are not stained with blood." Cuban officials have denied that any talks with the United States are going on.
Why talks are linked to pressure
The offer of talks sits alongside sustained economic and energy pressure. The United States imposed an oil blockade on Cuba earlier in 2026, contributing to fuel shortages and ongoing blackouts. An embargo is a ban on trade. A blockade goes further and tries to stop key deliveries from reaching the island.
Rubio said on May 5 that the status quo in Cuba was unacceptable and that the United States would address it. Later in May, he said the likelihood of a negotiated agreement was not high. In February, Trump had raised the prospect of a friendly takeover of Cuba. In July remarks to the press, Rubio said the United States wants Cuba to be prosperous and free.
Havana frames the pressure as coercion, not diplomacy. Earlier in September, Foreign Minister Bruno Rodríguez called the U.S. embargo a policy of "economic asphyxiation" and described the blockade as "genocidal." Cuba says the embargo cost its economy $8 billion between March 2025 and February 2026, the highest figure yet and 7 percent more than the previous period. Rodríguez said that total does not include U.S. restrictions on energy supply imposed in January 2026 and secondary sanctions imposed in May 2026. Secondary sanctions penalize other countries or firms for dealing with Cuba. Al Jazeera
Brazilian President Luiz Inacio Lula da Silva criticized the U.S. blockade in his 2026 General Assembly speech, saying 10 million people face collective punishment from an embargo and energy siege. Every year since 1992, the General Assembly has adopted by a large majority a non-binding resolution calling for lifting the U.S. embargo. Non-binding means it states the view of most states but cannot compel action. In July 2026, a vote on whether to hold debate on the Cuba embargo resolution drew 136 in favour, nine against and 30 abstentions.
What to watch next
The broader context here is a dual track that leaves little middle ground. Washington pairs a conditional opening with threats of force and tightening sanctions. Havana denies contact and tallies rising economic costs. For diplomats who work the Cuba file daily, the sequence matters. Pressure precedes outreach, and outreach is defined as transition, not coexistence.
Looking at what this means for General Assembly week, the test is whether any third party can create space for contact. The annual embargo resolution commands wide support, and Lula's intervention signals Latin American unease with the energy measures. Yet resolutions do not bind Washington, and Havana has rejected preconditions. Short declaratives will dominate. The risk of miscalculation is real.
