Castro, who stepped down as president in April but remains the leader of the Communist Party until 2021, spoke on Tuesday in Santiago de Cuba at the grave of his brother Fidel Castro, Cuba's revolutionary leader who died in 2016, Al Jazeera reported.
"Increasingly, senior officials of [US President Donald Trump's] administration, with the complicity of some lackeys, disseminate new falsehoods and once again seek to blame Cuba for all the ills of the region," he said in the presence of Cuba's current President Miguel Diaz-Canel.
After the restoration of diplomatic ties and a friendlier tone under former administration of US president Barack Obama, "once again the US government seems to take the course of confrontation with Cuba", he said.
Clad in military fatigues and cap, the 87-year-old Castro said that Cuba had proven throughout six decades of revolution it could not be intimidated by threats. Instead, it remained open, he said, to peaceful and respectful coexistence.
On January 1, 1959, Fidel Castro overthrew a US-backed authoritarian leader Fulgencio Batista and installed a Communist-run country on the doorstep of the United States, setting the scene for decades of Cold War hostility.
Currently, Cuba remains one of only a handful of communist states left in the world, and has been under a US economic embargo since 1962.
Trump's national security adviser, John Bolton, said in November that Washington would take a tougher line against Cuba, Venezuela and Nicaragua, calling them a "troika of tyranny".
