The International Fencing Federation (FIE) also said it was reinstating Kharlan, allowing her to take part in the team competition at the world championships in Milan.
Emmanuel Katsiadakis, the Greek president of the FIE, said the decision had been taken "after consultation with the International Olympic Committee".
Kharlan, the first fencer to face a Russian or Belarusian since the former's invasion of Ukraine, won 15-7 against Russia's Anna Smirnova on Thursday.
The 32-year-old four-time Olympic medallist refused Smirnova's handshake afterwards, instead offering her sabre to tap blades, but FIE rules state that the two fencers must shake hands.
Smirnova staged a 45-minute protest and refused to leave the competition strip.
Kharlan was disqualified, claiming afterwards that Emmanuel Katsiadakis, the Greek president of the FIE, had even assured her that it was "possible" not to shake hands and offer a touch of her blade instead following her victory.
"I thought I had his word, to be safe, but apparently, no," Kharlan said.
In response to her disqualification, the International Olympic Committee called for Ukrainian athletes to be treated "sensitively".
Then on Friday, IOC President Thomas Bach, a former Olympic fencer himself, sent Kharlan a letter saying she would be guaranteed a place at next year's Olympics in Paris regardless of whether she gained the qualification points.
In the Olympics, do we not say what "country" won the medals, fly their flag, play their anthem? It's not my narrative, but the one the Olympics has written.
Okay and if someone shot her at the competition would they be shooting her, or Russia? Her, obviously. Yours is a silly line of argumentation steeped in national symbolism.
You're attacking me instead of my point. Until you address it I have nothing more to say.
No, I made you look silly by attacking your point. There is a difference.
And again with the childish belittlements.
The point is that the athletes represent their nationalities in a very real way in international competition like the given one and the also discussed Olympics. To pretend otherwise is wildly disingenuous. You even make this point while deflecting blame onto a third party, then deny it vehemently a few posts later.
Obviously you're not changing your perspective here, and while I'm happy to sympathize with your points and world view, I don't share them. And without an argument in good faith on your part, I'm inclined to move on.
Have a good day!
