Daily US Times: Russian President Vladimir Putin has become one of the last world leaders to congratulate Joe Biden on his victory.
The Kremlin had said it would wait for official results from November’s election before recognising the victory.
The US President-elect was confirmed as winner on Monday by the electoral college.
Most world leaders congratulated Joe Biden within days of the 3 November elections, when it was clear he had defeated Donald Trump.
Mr Biden and Mr Putin had frosty relations when Biden served as vice-president under President Barack Obama.
Democrat Joe Biden won November’s election with 306 electoral college votes to Republican Donald Trump’s 232.
Confirmation by the electoral college was one of the steps required for the Democrat to take office.
President Trump said last month that he would leave office in January if Joe Biden were affirmed as the election winner by the electoral college, but he has continued to make unsubstantiated claims of widespread election fraud.
The Kremlin statement said Mr Putin wished Mr Biden every success and said he was “ready for collaboration and contacts with you”.
He “expressed confidence that Russia and the United States, which have a special responsibility for global security and stability, could, despite their differences, really help to solve the many problems and challenges facing the world,” the statement added.
But analysts say Joe Biden, who describes Vladimir Putin as an autocrat, is expected to take a tougher line on Russia than Mr Trump.
