MOSCOW — Former President Vladimir Putin was appointed Russia's new prime minister Thursday, securing a new place in power a day after leaving the Kremlin. His appointment was the final stroke in a precisely choreographed transition that allows the former KGB officer to leave the Kremlin without completely relinquishing authority.
Forced out of the presidency by constitutional term limits, Putin on Wednesday handed off his title to Dmitry Medvedev, a longtime protege, who in turn nominated his old boss as prime minister.
Since he anointed his successor, Putin has hovered at Medvedev's side during meetings and public appearances. Both men have said that they planned to run the country as a cooperative project.
"All the previous years we've been working together, and we'll continue to work together," Medvedev told the lower house of parliament Thursday. "There's no doubt that our tandem, our cooperation, will only grow stronger."
Later in the day, Russia announced that it was expelling two American military attaches who worked at the U.S. Embassy here, the State Department said.
The expulsion put an antagonistic start to this new administration, feeding into the questions hanging over Russia's leaders. But it was not clear who ordered the expulsion, or why it was timed on Medvedev's first full day in office. Russian officials had no comment.
The action was the latest in an exchange of diplomatic expulsions in which two Russians and three Americans have been sent home since November.
Sean McCormack, the chief State Department spokesman, said there were no plans for a response and refused to say whether the expulsions were connected. But Defense Secretary Robert M. Gates said at a separate briefing that "reciprocity" probably played a role.
"There are some intriguing developments in Moscow," Gates said. "But I don't read much into the attache thing other than just the usual tit-for-tat."
Some analysts had predicted that Medvedev would emerge as a more liberal and pro-Western ruler than Putin, who has sparred vigorously with the United States, Europe and some of the former Soviet republics. Others dismissed Medvedev as a puppet who will mask Putin's continuing rule.
But Medvedev is in a more powerful position now than is his mentor.
And in a country where the tradition of a single, dominant ruler is deeply ingrained, many are wondering whether the men will clash as Medvedev strives to take charge.
