The Russian Anti-Doping Agency has been under investigation by Wada since last year
Russia will miss this summer’s World Championships after athletics’ governing body voted to extend their suspension from international competition for state-sponsored doping.
However, some Russians may be able to compete under a neutral banner, if they can satisfy testing criteria.
Russia was suspended by the IAAF in November 2015, meaning athletes missed the Rio Olympics last year.
The country is now not expected to be fully reinstated until November.
London will host the World Championships between 4-13 August.
The decision to extend Russia’s suspension came at an IAAF Council meeting in Monaco on Monday.
Independent chairman of the IAAF Taskforce, Rune Andersen, told the council that the Russian Track and Field Federation (Rusaf) was unlikely to be reinstated until the World Anti-Doping Agency (Wada) declared the Russian Anti-Doping Agency (Rusada) code-compliant, probably in November.
However, the taskforce said concerns still exist about drug-testing procedures in Russia.
More than 1,000 Russian athletes were part of a state-sponsored doping programme between 2011 and 2015, according to the McLaren report, commissioned by Wada and published in December.
Athletes who can follow strict IAAF criteria and show they are clean may be allowed to compete – but not under a Russian flag. The IAAF said so far this year, 35 Russians had applied to compete as neutrals.
At the meeting, IAAF president Lord Coe also said that all nationality switches by athletes would be frozen.
He said the current rules were “no longer fit for purpose” and new proposals would be written up.
