To your list of law firm associations, add one more: the CIUS Leading Counsel Network. From the write-up in the European Lawyer, Issue 91, Nov./Dec. 2009 at 9, the nine firms cover Turkmenistan, Kazakhstan, Armenia, Russia, Azerbaijan, Kyrgyzstan, Ukraine, Moldova, and Belarus (my spell checker collapsed).
For general counsel who have to find local counsel in any of those countries, contacting a member of the group would be a reasonable step (See my post of Feb. 21, 2008 #2: law firm networks with 7 references.).
