We are about to move into a new phase when Russian state-controlled energy companies are opened for investment with cooperative foreign firms. It makes sense to have someone with international experience ? either corporate or political ? leading that process at the head of those companies.

In practice, we are not expected to see much volume in the following two weeks.
