MOSCOW (Reuters) - A possible ban on visas for the heads of Russia's two biggest energy firms, Rosneft and Gazprom, may hamper their international partnerships but also harm their Western partners and push the two towards the East.
Rosneft, the world's largest listed oil company by production and reserves, and Gazprom, the top natural gas producer, rely heavily on overseas markets for their sales. Their chief executives travel abroad frequently to promote their businesses and strike deals with international partners.
