Russian President Dmitry Medvedev and US President Barack Obama will sign a declaration on a new nuclear arms reduction treaty on 1 April, a top Kremlin aide has said.
At the meeting in London, Mr Medvedev and Mr Obama will also sign a general declaration on US-Russian relations.
Russian officials have said that signing a successor to the Strategic Arms Reduction Treaty (START 1) is a priority in relations with the new US administration, which has pledged to 'reset' ties with Russia after they reached post-Cold War lows under former President George W Bush.
