World Athletics on Thursday fined Russia's track and field federation $10 million for breaching anti-doping rules and capped at 10 the number of Russians allowed to compete as neutrals at the Tokyo Olympics.
The system of allowing Russian athletes to take part as Authorised Neutral Athletes, World Athletics president Sebastian Coe warned, "will be suspended if $5 million of the $10m fine is not paid by 1 July 2020".
"The remaining $5 million of the fine will be suspended for two years, to be paid immediately if during that period RUSAF (the Russian federation) commits a further breach of the Anti-Doping Rules or fails to make meaningful progress towards satisfying the reinstatement conditions set by Council.
