The United States has imposed a fresh round of sanctions on five Cuban entities and eight individuals, citing their involvement in securing weapons and maintaining military relationships with foreign powers, including China and Russia.

Secretary of State Marco Rubio announced the designations on Thursday, which fall under an executive order signed by President Donald Trump in May that expanded sanctions against Cuban government officials, security forces, and their supporters.

Among the targeted entities are subsidiaries of the military conglomerate GAESA, a military holding company, and a military aircraft repair business, according to the U.S. State Department.

Key individuals sanctioned include Álvaro López Miera, minister of the Cuban Ministry of the Revolutionary Armed Forces (MINFAR), Chief of the General Staff Roberto Legra Sotolongo, and Cuba's military attachés to both Russia and China.

Rubio asserted that the Cuban government utilizes its military and intelligence services to spy on the U.S., further accusing the nation of serving as a staging ground for operations against America by Russia, China, and Iran.

This action builds upon earlier designations this year targeting GAESA and MINFAR directly.

Cuban authorities did not immediately respond to requests for comment.

Washington has consistently applied sanctions against a range of Cuban entities and individuals, including the island nation's president, in an effort to intensify pressure on Cuba's communist leadership.

These latest measures follow a national emergency declaration earlier this year by the United States, which imposed tariffs on any country supplying oil to the island, a move that has contributed to frequent power outages across Cuba.
