Moscow and Washington have agreed to moderate their rhetoric in a bid to improve strained ties, Russian Foreign Minister Sergey Lavrov said after a meeting Tuesday between President Vladimir Putin and Secretary of State Condoleezza Rice.

"The president supported the American side's understanding that it's necessary to tone down the rhetoric in public statements and concentrate on concrete business," Lavrov, who participated in the meeting, told reporters.

In one key area, Lavrov said that the two countries agreed to search for a mutually acceptable solution on Kosovo, but failed to achieve a breakthrough.

"It was agreed to search for a solution on Kosovo that would be acceptable for all, but there is no such solution immediately in sight," he said after after taking part in the meeting at Putin's residence outside Moscow.
