Senator Marco Rubio will be heading to New York from September 20 to 23 to attend the High-Level Week of the 81st United Nations General Assembly alongside President Donald Trump, as announced by the State Department on Friday.

President Trump is scheduled to address the Assembly on September 23, taking the podium as the second speaker of the morning session, following Brazil's opening remarks.

The official statement outlined that the U.S. delegation will carry an agenda focused on "peace, prosperity, and the primacy of nations," aiming to encourage the multilateral body to return to its core mission of maintaining international peace and security while respecting each state's sovereignty.

The State Department highlighted that Washington intends to use the week as an opportunity to collaborate with other member countries in achieving tangible outcomes for the American people, building upon the historic UN reforms enacted in the past year.

Beyond the plenary activities, Rubio will engage in bilateral meetings with foreign ministers from various countries to discuss shared priorities in security and economic matters. Among the anticipated meetings is one with Russian Foreign Minister Serguéi Lavrov, focusing on Ukraine and bilateral relations between the two powers.

This trip occurs amid heightened pressure from Washington on Havana. Just a day before the announcement, Rubio declared new sanctions against eight entities and three individuals linked to Cuba's military apparatus and the nickel sector.

These measures add to those implemented at the beginning of September, when the Trump administration expanded restrictions against five Cuban state entities and a grandson of Raúl Castro, including the Banco Exterior de Cuba.

Rubio has described the Trump administration's strategy as closing "every escape valve" for the Cuban regime, a policy that has intensified in the months leading up to the gathering in New York.

In July, a leaked diplomatic cable revealed that Rubio instructed U.S. embassies to pressure foreign governments ahead of a UN debate on Cuba, categorizing countries based on their expected stance. The debate concluded with 136 votes in favor of the resolution on the embargo.

The general debate of the 81st UNGA will span from September 22 to 26 and on September 28, with major global issues like the war in Ukraine, the situation in Gaza, international trade, and migration dominating the agenda.
