Havana - The United States has no right to impose unilateral measures on entities from Cuba or any other country that do business with Venezuela, Cuban Foreign Minister Bruno Rodriguez said on Twitter.

The minister's statement came after the Government of the United States included the company Cubametales in its unilateral list of sanctioned enterprises for doing business with Venezuela, as the firm continues to import oil from the South American country.

The United States has no right to impose unilateral measures on entities from Cuba or any other country that do business with Venezuela. It is a violation of international law, of the norms that govern trade and an attack on relations among sovereign States, Rodriguez wrote on his account @BrunoRguezP.

According to the US Department of the Treasury, Cuba, in exchange for oil, continues to provide support, including defense, intelligence and assistance to security, to the administration of President Nicolas Maduro.

Washington has used Cuba's support for Venezuela on several occasions to justify new measures against the Caribbean island.

In light of that interfering stance, Havana has repeated that its solidarity with Venezuela is not negotiable.
