Cuban former Leader Fidel Castro said on Tuesday that the US "measure to lighten the restriction of trips by Cuban-Americans to Cuba is positive, however it is minimum."

Castro said in his column "Reflections" published on Tuesday by Cuba Debate website that still "many other measures are missing, including the elimination of the killer Law of Cuban Adjustment."

The 1966 law, which the US exclusively applies to Cuba, grants Cubans who reach US soil automatic residency.

In his article entitled "Days that can not be forgotten," Castro mentioned the attack against Cuba on April 1961 made by anti-Cuba forces supported by Washington.

He urged the US to make self-criticism and guarantee that what happened in 1961 would never repeat.

Castro said, "the great power" could do the same to any Latin American country, and this already has happened, for example in Dominican Republic, Panama, Guatemala, Chile, Argentina and Venezuela, either by directly sending troops or by supporting their domestic opposition.

The US president Barack Obama lifted restrictions on travel and money transfer to Cuba, opening a crack in a 47-year-old embargo against Havana.

In his article, Castro also recognized Obama's disposition to cooperate on issues like climate change.
