BEIJING, August 3 (RIA Novosti) - A resolution on the current diplomatic conflict between Russia and the United Kingdom, which erupted after the murder of Alexander Litvinenko, depends on Britain, the Russian foreign minister said Friday.

"We are trying to react as reservedly as possible...it is up to British now," Sergei Lavrov said.

After Moscow officially refused in early July to extradite Andrei Lugovoi, accused by Scotland Yard of murdering Litvinenko, tensions escalated, and London expelled four Russian diplomats, a move mirrored by Russia.

Visa restrictions have also been slapped on Russian officials by Britain, and vice versa, and antiterrorism cooperation has been suspended.
