Venezuelan President Nicolas Maduro has described his last week's meeting with Russian President Vladimir Putin as the most useful session in his whole political career.

"This was the most useful meeting in my career. We strengthened the process of cooperation between Russia and Venezuela in the sphere of military-technical cooperation," Maduro told a press conference.

Last Friday Maduro finished his visit to Moscow. As a result, the sides signed agreements on cooperation in the oil extraction and mining industries, servicing Venezeulan weapons systems and delivering wheat to the South American country. According to the Venezuelan president, bilateral projects are worth over $6 billion of investment.

Russia and Venezuela are implementing joint investment projects in energy, agriculture, geological exploration, pharmaceuticals, as well as in the spheres of information technologies, nuclear medicine, military-technical cooperation and others.
