Cuban strongman, Raul Castro’s comments to Cuba’s National Assembly were his first on Trump’s June announcement of a partial rollback of the Cuba-U.S. detente achieved by the then-President Barack Obama. They contained echoes of the harsh rhetoric from the past.

“Any strategy that seeks to destroy the revolution either through coercion or pressure or through more subtle methods will fail,” he told legislators.

Surrounded by Cuban-American exiles and Cuban dissidents in Miami, Trump announced last month that the U.S. would impose new limits on U.S. travellers to the island and ban any payments to the military-linked conglomerate that controls much of the island’s tourism industry. He said the U.S. would consider lifting those and other restrictions only after Cuba returned fugitives and made a series of other internal changes including freeing political prisoners, allowing freedom of assembly and holding free elections.

Trump’s policy retained elements of Obama’s reforms but tightened restrictions on travel and employed harsh rhetoric on human rights.

On Friday in Washington, the Trump administration said it was suspending for another six months a provision of the U.S. embargo on Cuba.

The State Department said it told Congress that it will keep suspending a provision of the Helms-Burton Act that deals with property seized from Americans. The provision lets Americans use U.S. courts to sue non-American companies that operate and deal with property confiscated after Fidel Castro’s revolution.

Speaking to the National Assembly, Castro called the Trump administration’s policies a “setback,” though he reiterated his government’s position that it would work to normalize relations with Washington.

Earlier in the legislative session, Economy Minister Ricardo Cabrisas announced that Cuba’s economy is growing again after a dip last year.

Cabrisas said the economy grew around 1% in the first half of 2017. That puts GDP growth on track to hit 2% for the year.

The government said the economy shrank last year by 1 percent amid falling support from troubled Venezuela. That was the first decrease reported in two decades. Cabrisas said that instability in the supply of Venezuelan oil weighs on the country but tourism, construction, transportation and communications were growing.

Foreign media did not have access to the National Assembly session.
