(Recasts with Russian Olympic Committee comments, RUSADA director general comments)

MOSCOW, Sept 23 (Reuters) - The head of Russia's Olympic Committee said on Monday that his country's participation at the 2020 Tokyo Olympics was at risk over the alleged manipulation of anti-doping laboratory data.
WADA said earlier on Monday it was looking to determine whether the Russian anti-doping agency RUSADA was compliant with international anti-doping regulations after it found inconsistencies in Moscow's laboratory data.
Stanislav Pozdnyakov, the president of Russia's Olympic Committee, said the situation was "very serious" and could jeopardise Russia's Olympic participation.
"We have spent vast diplomatic efforts to regain the trust of the international sports community and for Russian athletes to have the right to take part in Olympics without any restrictions," Pozdnyakov said in a statement.
"But now we again run the risk of facing sanctions for reasons with which we have nothing to do."
The International Olympic Committee (IOC) put restrictions on Russia's participation at the last two Olympic Games.
Russia was barred from the Pyongchang Winter Games last year as punishment for alleged state-sponsored doping at the 2014 Sochi Olympics. However, some Russians with no history of doping were cleared to compete as neutrals.
The IOC chose not to ban all Russian athletes from the 2016 Olympics in Rio de Janeiro after a WADA-commissioned report revealed a state-backed doping programme across many sports.
Russia has three months to respond to WADA's concerns, the head of RUSADA and the Kremlin said.
When contacted by Reuters, RUSADA director general Yuri Ganus would not comment on the nature of the inconsistencies uncovered by WADA. He said the laboratory's database had not been under the agency's jurisdiction.
"I am profoundly convinced that new people are needed to get out of this anti-doping crisis," Ganus said. "We need to get out of this vicious circle."
Kremlin spokesman Dmitry Peskov said the Kremlin was aware of the issue, but that it was a matter for the country's sports authorities.
RUSADA was reinstated by WADA last year after the Russian agency served a suspension of nearly three years over evidence of mass doping in Russian athletics. The handover of laboratory data to WADA had been a condition for its reinstatement.
Russian Sports Minister Pavel Kolobkov said the ministry would cooperate with WADA in determining what was wrong with the data.
"We were told that the database submitted to WADA is slightly different that from the copy that WADA experts took in Moscow in 2019," Kolobkov said in a statement.
"Experts in the field of digital technology from both sides will determine what these discrepancies are and what they are linked to." (Reporting by Gabrielle Tétrault-Farber and Tom Balmforth Editing by Andrew Osborn and Christian Radnedge)
