CUBAN President Miguel Diaz-Canel has slammed United States efforts aimed at overthrowing the Caribbean nation’s constitutional order, including threats to use force.

President Diaz-Canel took to social media on Tuesday to issue a warning against the “imperial ambitions” of the US to seize Cuba’s resources, properties and economy.

US President Donald Trump suggested on Tuesday that action against Cuba was imminent.

After strangling Cuba’s economy by stopping vital oil imports from Venezuela, President Trump and his Secretary of State Marco Rubio have made it clear they see the Caribbean nation as their next target.

President Trump said: “Cuba right now is in very bad shape.

“And we’ll be doing something with Cuba very soon.”

The Trump administration has also made it clear it wants President Diaz-Canel to step down as the US continues negotiating with the Cuban government, according to a source.

Mr Diaz-Canel said the US was engaged in a strategy of economic strangulation that has paralysed vital services such as hospitals and transportation, leaving the country without crude oil for more than three months.

He said the blockade is clearly a violation of international law, attempting to subdue the Cuban people through hunger and energy deprivation.

The entire island was blacked out earlier this week after the electrical grid failed.

Cuba’s Ministry of Energy and Mines said on social media that it had managed to restore the electrical system in the western town of Pinar del Rio and the south eastern province of Holguin, while some “microsystems” were beginning to operate in various territories.

President Diaz-Canel said the current energy crisis is the direct result of a fierce economic war meticulously orchestrated by the White House.

He said: “They use an outrageous pretext: the severe limitations of the weakened economy that they have attacked and attempted to isolate for more than six decades.”

The actions of the US amounted to “collective punishment against the entire Cuban people, with the aim of forcing them to surrender by suffocating vital sectors, such as energy and food,” he added.

“They seek to suffocate in order to force us to surrender.”

The Cuban President insisted that faced with any external aggression, the country possesses unwavering resolve, declaring: “Cuba is accompanied by one certainty — any external aggressor will encounter an impregnable resistance.”
