A senior Russian Cabinet member says Moscow expects President Barack Obama to show more flexibility in a dispute over U.S. missile defense plans following his re-election.

Deputy Prime Minister Dmitry Rogozin said Thursday that Moscow hopes that Obama will take into account Russia's concerns about the U.S.-led NATO missile defense for Europe.

The controversy over the planned shield has strained the relations between the U.S. and Russia. Moscow has rejected Washington's assurances that the shield is intended to fend off potential missile threats from Iran and voiced concern the system could eventually grow powerful enough to threaten Russia's nuclear deterrent.

In March, Obama, unaware that he was speaking on an open microphone, told Dmitry Medvedev, then Russian president, that he would have more flexibility on the issue after November's election.
