The British prime minister will visit Moscow in September, as the two countries plan to end years of tension following the murder of former KGB agent Alexander Litvinenko in England.
The official announcement by the Russian Embassy in London comes after David Cameron previously said he had received an invitation from the Russian President Dmitry Medvedev in November.
The two countries are trying to improve their diplomatic relations that was marred after the assassination of the high-ranking intelligence officer in 2006.
Charge d'affaires at the Russian Embassy in London, Alexander Sternik, said that Cameron is expected to travel to Moscow in early September.
"We hope it will be a very significant step forward in improving our relationship," he said.
"We are ready, as soon as London is ready, to re-establish full-fledged co-operation in all areas."
It will be the first visit to Moscow by a British premier since Litvinenko was killed.
Accordingly, the diplomatic relations fell to a post-Cold War low after Moscow declined to extradite the man the British government wanted to put on trial for the murder.
A delegation of business leaders will accompany Cameron to Russia where they are expected to partake in the meeting with Medvedev.
Sternik said that Cameron and Medvedev's talks in Deauville would be "heavily dominated with economic, trade and investment cooperation issues" along with discussing about the prospects for developing dialogue on political issues.
