Russian President Vladimir Putin has signed a nuclear energy cooperation deal with Argentina during a visit to Buenos Aires.
Putin and President Cristina Fernandez said the Russian atomic energy corporation, Rosatom, would be involved with the construction of two units at an existing plant.
Argentina has one of the world's largest deposits of shale oil and gas but only a few companies have made commitments to develop the fields, as many fear the government's interventionist energy policies.
Although a deal on the shale deposits was not announced on July 12, Fernandez said members of the Russian delegation traveling with Putin will visit Argentina's Vaca Muerta (Dead Cow) deposit in Neuquen Province.
After a dinner, the Russian leader was heading to Brazil for a summit of leaders from the BRICS nations: Brazil, Russia, India, China, and South Africa.
