Russia seems to be in no hurry to crack down on corporate bribery. It was back on April 1 that the U.S. Justice Department unsealed documents showing in remarkable detail how the German carmaker Daimler had paid millions of euros in bribes to Russian government officials. The bribes, according to the Justice Department, were paid to clinch sales of patrol cars for the police and sedans for the presidential motorcade. In Russia, the response was weeks of official silence. Finally, late last week, the Russian Ministry of Interior announced an internal investigation into its car purchases. This week, the prosecutor general vowed in a televised meeting with government officials that there would be no cover-up. Still, the Daimler case is the latest in a series of cross-border investigations into corporate bribery that show a stark difference in how Russia and other nations approach corruption. A reluctance to prosecute cases in Russia, even when foreign courts have already handed down verdicts, casts doubt on repeated pledges of President Dmitri A. Medvedev to open a broad front against corruption. The governments of Germany and the United States, in particular, have made headway in going after companies that pay bribes, part of an international crackdown promoted by the Organization for Economic Cooperation and Development. The Russians, who are not part of that group, seem highly reluctant to do anything about such bribes. In case in 2007 involving the engineering giant Siemens, prosecutors in Germany published a list of two dozen names and positions of Russian officials they said had taken bribes. Even then, the police in Russia did not pick up the lead. 'I thought I might be questioned, but that never happened,' Nikolai I. Galevko, one of the officials whose names appeared on the list, said by telephone Wednesday from his home in a provincial town south of Moscow. 'I was never afraid I would be arrested,' said Galevko, whom the German court found that Siemens had paid 147,600 euros, or $195,100, in bribes for business at the provincial telephone company where he was a vice president. Galevko denied he ever took money from Siemens. Even as details of the Daimler case emerged, another came to light. German prosecutors revealed that they were investigating whether the German branch of Hewlett-Packard had paid a kickback of 8 million euros to win business equipping the Russian prosecutor general's offices with computers. A branch of the Russian prosecutor's office, the Investigative Committee, searched Hewlett-Packard's Moscow office. It was not disclosed what action, if any, the committee had taken to search its own offices. The German authorities have arrested three people in the Hewlett-Packard case. And in the United States, the Securities and Exchange Commission and Justice Department have reportedly joined the investigation into whether Hewlett-Packer violated a U.S. law, the Foreign Corrupt Practices Act. The United States claims jurisdiction for bribery that takes place anywhere in the world if it involves companies whose shares trade in the United States or that do business there.
