Tillerson was a friend of Igor Sechin, the executive chairman of Rosneft, the Russian state oil company, and leader of the Kremlin's "Siloviki" (security/military) faction, who has been described as "Russia's second-most powerful person" after Putin. Exxon owns a dacha next door to Sechin's and Tillerson would often visit him there. Tillerson led Sechin on a tour of New York City, dining on caviar with him and Putin at the "Per Se" restaurant. In 2006, Exxon avoided making any government concessions in its Sakhalin-I oil field after Royal Dutch Shell was forced to sell half of its ownership in Sakhalin-II by the Russian government.
