Speaking to reporters on Thursday, Rubio said diplomacy “remains our preference with Cuba”, but added: “I’m just being honest with you, you know, the likelihood of that happening, given who we’re dealing with right now, is not high.”
He also accused Cuba of being “one of the leading sponsors of terrorism in the entire region”, which Rodríguez vehemently denied in a post on X.
The Cuban foreign minister criticised Rubio for trying to “instigate a military aggression” and accused the US government of “ruthlessly and systematically” attacking his country.
Cuba is suffering from a fuel crisis exacerbated by an effective US oil blockade, while under pressure from the Trump administration to make a deal.
Its citizens have experienced extended blackouts and food shortages over the last few months.
Rubio said the country had accepted a US offer of $100m (£74.4m) in humanitarian aid.
Trump has repeatedly sought to exert pressure on Cuba and has openly discussed toppling its communist regime.
The US has demanded political and economic reforms but the specifics are unclear beyond a leadership change. They could include a pledge to open up the economy to more foreign investment and a commitment to end the presence of Russian or Chinese intelligence agencies on the island.
Wednesday’s indictment of the former Cuban president is seen by some as reminiscent of Trump’s seizure of Venezuelan President Nicolás Maduro in January.
Asked by reporters whether – and how – his government would get Castro to the US to face the charges, Rubio replied: “I’m not going to talk about how we’re going to get him here, if we were trying to get him here, why would I say to the media what our plans are about that?”
