Russian athletes won't be allowed march under their country's flag later today.
It means the 168 athletes competing as "Olympic Athletes from Russia" (OAR) will not be able to march under their country's flag at today's closing ceremony.
IOC President Thomas Bach said a condition of Russia's ban being lifted is that no further positive drug tests come out of Pyeongchang.
Two of the four athletes who tested positive in Pyeongchang were Russian, including a curler who had to return his bronze medal.
"The IOC executive board decided first not to lift the suspension of the Russian Olympic Committee for the closing ceremony," Mr Bach said.
"Therefore, no delegation of the Russian Olympic Committee will have taken part in these Olympic Winter Games."
