Andrew Kramer at the Times digs into the Oleg Shvartsman story, and gives particular attention to Renault’s due diligence and business dealings with AvtoVaz and Sergei V. Chemezov:

For big Western companies, the prevalence of former Federal Security Service agents in Russian business is raising questions of ethics and due diligence, as a growing number — including Boeing, Exxon Mobil and Renault — have business transactions with Russian companies linked to former spies or members of the political police. Boeing and Exxon declined to comment on their companies’ due-diligence criteria for deals with former K.G.B. officials. A spokeswoman for Renault said her company was “not concerned” with the matter.
