U.S. President George W. Bush will discuss with President Vladimir Putin Russian contributions to Iran\'s nuclear-power program during this week\'s summit in Moscow and St. Petersburg. Bush\'s national security adviser, Condoleezza Rice, told journalists that Bush \"intends to talk a lot about the Russian-Iranian relationship.\" \"It has been a problem for several years,\" Rice said. \"We\'ve made a lot of progress with the Russians on the counterterrorism front.
