Russian Sports Minister Pavel Kolobkov said on Monday that Moscow had done everything to try and resolve its doping scandal, after Russia was banned from the world's top sporting events for four years.

The World Anti-Doping Agency (WADA) banned Moscow from events including the next Summer and Wwinter Olympics and the 2022 soccer World Cup, for tampering with laboratory data. (Some athletes may be able to compete as neutral parties.)

"Everything possible was done to resolve this situation. Everything possible," Kolobkov told reporters at a news conference in Moscow. 

WADA's executive committee took the decision after concluding that Moscow had tampered with laboratory data by planting fake evidence and deleting files linked to positive doping tests that could have helped identify drug cheats.

The decision to punish Russia with a ban was unanimous, a WADA spokesman said.
