The embassy said that their spat was damaging the economies of both Britain and Russia
The British embassy in Moscow has warned of the damage being done by the dispute between TNK-BP's shareholders, BBC News reported.
The oil company is half-owned by BP, with the other half owned by a group of Russian billionaires known as AAR.
The embassy said that their spat was damaging the economies of both Britain and Russia as well as harming the global energy market.
It also accused AAR's members of using parts of the Russian government to help them in their fight with BP.
"The way shareholders have manipulated elements of the Russian state bureaucracy and the way this has been allowed to continue is very disappointing," an embassy spokesman said.
"We will continue to stress to the Russian government the importance of a resolution between the shareholders in full accordance with the rule of law."
The Russian shareholders deny they want control of TNK-BP.
