The agreements were signed by Rosneff President Igor Sechin, and Zarubezhneft General Director Serguei Kudriachov, while the Cuban party was represented in the signing by Cupet General Director Juan Torres.
The signing ceremony was also attended by Cuban Deputy Minister of Energy and Mines Ruben Cid and Cuban ambassador to Russia Emilio Loazada.
During its stay in RussiaÂ�s second most important city, the Cuban delegation took part in a panel about the compatibility between the Russian and the Latin America and the Caribbean economies.
In his speech at the panel, Lozada highlighted that the member nations of the Bolivarian Alliance for the Peoples of Our America (ALBA) chiefly offer big opportunities to Russian investments.
The Cuban diplomat said that the interest in economic relations is not only important, but also the political rapprochement between Moscow and ALBA.
Loazada told Prensa latina that the presence of the Cuban delegation to the Economic Forum in Saint Petersburg is an expression of the rejection to the US and its allies' attempts to isolate Russia with its sanctions.
