Venezuela's vice president is visiting Russia, voicing hope for stronger ties with Moscow amid the U.S. pressure.

Delcy Rodriguez said after Friday's talks with Russian Foreign Minister Sergey Lavrov that Venezuela will rely on supplies of food and medicines from Russia as it faces a U.S.-led blockade and hold the door open for more Russian investments.

Lavrov reaffirmed strong support for Venezuelan President Nicolas Maduro and criticized the U.S. for waging a "cynical campaign aimed at ousting the legitimate government of Venezuela." He strongly warned Washington against military intervention.

Lavrov accused the U.S. and its allies of using economic sanctions and assets freezes to provoke a humanitarian crisis in the country.

He said that Russia has delivered a humanitarian aid shipment to Venezuela and will provide more such assistance.
