U.S. President Barack Obama is likely to visit Russia in the first half of 2013, the Kremlin said on Tuesday. Yury Ushakov, a foreign policy adviser to President Vladimir Putin, gave no further details. Obama and Putin have both signalled since winning presidential elections this year that they want an improvement in U.S.-Russian ties. Putin invited Obama to visit Russia after the U.S. leader's election for a second presidential term last month, according to a report of Reuters.
