Such an obligation will be imposed by the Commission for the Control of Foreign Investment, which approves deals on the withdrawal of foreigners from assets in Russia. In its latest decision the commission has already obliged the buyers to place 20% of the shares on the stock exchange, Finance Minister Anton Siluanov told Izvestia, without specifying the name of the company.
