Russia has bilateral extradition treaties with a number of states — primarily CIS members and a selection of other jurisdictions. For most Western European countries, the United States, Canada, Australia, and other major commercial partners, Russia does not have bilateral extradition treaties. In the absence of a treaty, extradition from Russia to those countries is not available on a legal basis, and Russia will not extradite its own citizens in any circumstance.
For a foreign national who is outside Russia and becomes the subject of a Russian criminal investigation, the theoretical extradition risk from Russia is therefore limited — but not eliminated. For a foreign national from a CIS country, an extradition treaty may exist. For transit through jurisdictions that have different extradition relationships with Russia than the foreign national's home country, case-by-case assessment is necessary.
