Russia and the World Anti-Doping Agency (WADA) had reached an understanding on the handover of data from the former Moscow anti-doping laboratory, Kremlin spokesman Dmitry Peskov said.
"The data was ready to be handed over [to WADA] during the previous visit. Certain work disagreements erupted in regard to data storage devices and so on," he noted.
"I would say that these issues were rather not substantial, but were of logistics nature. Intensive contacts are currently underway at the level of our sports departments and an understanding has been reached with WADA concerning the future work," TASS cited the spokesman as saying.
Russia was due to hand over the data to WADA by the end of 2018 in order for RUSADA, its national anti-doping agency, to keep its accreditation. A WADA delegation is in Moscow to retrieve the laboratory data, having returned empty-handed last month, Reuters reported.
Sixteen national antidoping organizations (NADOs) have called on the World Anti-Doping Agency (WADA) to take immediate action following Russia's failure to meet a December 31 deadline to hand over data from its antidoping laboratory.
