The Russian athletics federation must cut ties with all past dopers, resolve outstanding disciplinary cases and investigate potential further cases before it can be reinstated, world athletics' governing body the IAAF has said.
On Friday the IAAF revealed the conditions Russia must meet in order to be readmitted, leaving a race against time for Russian athletes to compete at the Rio Olympics next summer.
The Russian federation (ARAF) was suspended last month in the wake of damning revelations contained in a report by a World Anti-Doping Agency (WADA) independent commission of systematic doping and cover-ups in the country.
IAAF president Seb Coe said again there is "no timeline" in place for Russia's reinstatement and added: "The conditions we have announced leave no room for doubt.
"Russia must demonstrate verifiable change across a range of criteria and satisfy our task force that those criteria will be met permanently. There is no timeline for Russia. It is up to them to implement verifiable change both in anti-doping practice and culture."
Under the reinstatement conditions, Russia must demonstrate that it is in full compliance with the WADA programme as well as the IAAF rules, and that the Russian Anti-Doping Agency (RUSADA), currently suspended, is able to operate without interference.
That follows claims that Russia's security services were involved in the doping programme.
An IAAF task force will determine whether Russia is in compliance with its verification criteria.
The world governing body said the Russia must be able to show that none of its directors, officers or staff have any prior links to doping, while introducing a comprehensive code of ethics.
The IAAF said it would take responsibility for testing Russian athletes while RUSADA remains suspended in order that those athletes are in a position to return to competition once Russia's suspension is lifted.
All samples collected are to be tested in laboratories outside Russia.
The IAAF task force's first trip to Russia to begin its oversight is scheduled for January 2016.
