Russia will find out in May if it can send athletes to Rio 2016, while five more nations are in “critical care”, says IAAF president Lord Coe.
Russia’s athletics federation was suspended by the governing body in November after being accused of “state-sponsored” doping.
A taskforce, set up by Coe, said Russia has made “considerable progress” but there is “significant work to be done”.
Ethiopia, Morocco, Ukraine, Kenya and Belarus are also under scrutiny.
Lord Coe said: “Ethiopia and Morocco both need to implement adequate and robust testing in and out of competition.
“Kenya, Ukraine and Belarus have been put on a monitoring list for 2016 to strengthen their anti-doping regimes and make sure their journey to compliance is completed by the end of the year.
“The monitoring process is not new. It is complementary to the World Anti-Doping Agency’s processes.
“There are no immediate sanctions. It is just a wake-up call. Sanctions will only be considered if they don’t comply with requirements.”
