"In a display of double moral standards, the United States announces ‘humanitarian aid’ to the people of Venezuela after having strangled it by economic means in the form of sanctions and illegal confiscations. The United States is destroying the principle of international law by providing ‘humanitarian aid’ to the coup d'etat," Morales wrote on Twitter.
The statement comes after media reported on 7 February that the first batch of US humanitarian aid to Venezuela — two 50-tonne containers and at least six trucks — had reached the Colombian border city of Cucuta.
Meanwhile, the opposition also plans to hold an international conference for humanitarian aid donors in Washington on February 14.
Venezuela has been suffering from political and economic crisis triggered by the fall of global oil prices, with the opposition actively using the deteriorating humanitarian situation in its rhetoric.
