MOSCOW, Dec. 10 - Ukraine has started revising its cooperation with the CIS to see whether it could be more involved in its various programs, said President Viktor Yanukovych.

"This [a CIS summit] is a forum that has proven its efficiency. This is why Ukraine is inventorying its participation in the Commonwealth. In particular, we are considering opportunities to join various branch organizations of the CIS and lift reservations on a number of CIS documents that were made earlier," Yanukovych said at an expanded session of the CIS heads of state.
