"In the short term, I do not see any significant investments coming from the United States into the energy sector of Russia despite the political warming of relations between Moscow and Washington," Millian said on the sidelines of the ongoing Russian oil and gas industry week in Moscow.
According to the official, US corporations will not "break the rules of the game" and violate the anti-Russia sanctions.
"In regards to the energy sector, currently, there is a limited cooperation in the energy sphere in terms of investment opportunities," Millian added.
Relations between Russia and the United States went downhill in 2014, when Washington accused Moscow of fueling the Ukrainian crisis and imposed several rounds of sanctions as a punitive measure. The restrictions targeted Russia's banking, energy and defense sectors.
The Russian authorities have refuted the allegations, warning that the Western sanctions are counterproductive. In response to the Western restrictive measures, in August 2014, Russia announced a one-year food embargo on some products originating in states that imposed sanctions against it. The ban has since been extended for another year.
