Members of the World Anti-Doping Agency have begun to bicker amongst themselves about when and if Russia's anti-doping agency will be welcomed back into their fold.
RUSADA remains suspended and WADA says it will continue to be non-compliant until it has met all the criteria for reinstatement.
WADA director general Olivier Niggli says it is up to Russia how long things drag on.
"We follow our process," Niggli told Reuters. "How long is it going to last?
"The Russians have the means to solve the problem if they want to. The ball is in their court.
"What matters to me is that we follow the process, we've outlined the road map and we follow that."
Some Foundation Board members, however, feel the Road Map has hit a dead-end and it is time to conclude the matter.
International Olympic Committee member Patrick Baumann, who also sits on the WADA executive committee, asked the Foundation Board how much longer it was willing to let the dispute drag on.
"We don't challenge the Road Map, we question how long we want to follow it," Baumann said. "What, for the next 10, 20, 30 years? What are we asking?
"Are we asking the head of state to come here and personally apologise?"
The IOC reinstated Russia on February 28 after the remaining tests from the PyeongChang Winter Olympic Games all returned negative but WADA continues to stand firm.
The WADA meeting appeared to expose a split that seems to be building between hardliners and board members who also have ties to the IOC.
But Canadian senior IOC member Dick Pound, who helped set up WADA and was its first president, continues to be among the loudest voices demanding full compliance before Russia is welcomed back.
"They (Russia) are laughing at us," Pound told Reuters. "It seems to me there has been an unrelenting effort to try to get them back in as opposed to saying, 'you're out, persuade us you have had a change of mind in conduct and maybe you come back'.
"You get the impression that the IOC and the Olympic movement in general feels Russia is too important to be left out."
Russia has met many of the demands but two items remain outstanding; access to the Moscow laboratory and acknowledging the findings of the WADA-commissioned report that found evidence of widespread state sponsored doping.
Russian authorities have repeatedly denied the existence of state-sponsored doping.
