Nanotechnology, an area of science where matter in manipulated on the atomic scale, has been made a national priority in Russia, as part of measures aimed at diversifying the economy away from oil and gas exports.

He had also been a Foreign Ministry official since 1968, serving at Soviet and Russian embassies in Afghanistan, the U.S. and the Philippines. He was also ambassador to a number of countries, notably Australia and Japan. The diplomat had been deputy foreign minister since 2007, and also held the post in 2000-2004.
