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.
So to be clear, she is throwing a tantrum because the Ukrainian contestant didn't want to shake hands with a citizen of the country that has been killing her people?
Yes. I think this is less a tantrum, and more of a "fuck you" from Smirnova to Kharlan, but your interpretation is fine.
The rules state that the competitors must shake hands at the end of a bout, and that the penalty for refusing to shake hands is a black card. At the beginning of the pandemic, this rule was suspended, and was replaced with saluting and tapping blades. It is not clear whether the handshake rule is back in effect at the international level (which in itself is a huge problem - if athletes can't look up the rules, it's hard to follow them).
As an online observer, these are the facts I was able to gather. At the end of this bout, Kharlan offered her blade for the blade tap, and instead of reciprocating, Smirnova offered her hand for a handshake. Kharlan then left the piste without tapping blades or shaking hands, and Smirnova launched her complaint which (per the rules) required her to remain on piste until the issue was resolved. The officials decided the complaint was legitimate, and black carded Kharlan.
All that follows is my own speculation. Kharlan offered the blade tap but was refused. Depending on whether the handshake rule is officially reinstated (and it seems that many athletes at this particular competition were just tapping blades without a handshake) she may have been able to lodge her own complaint that Smirnova was unwilling to tap blades. They could have just had an old fashioned stand-off, with one fencer extending their blade for the tap and the other extending their hand for the handshake, neither willing to compromise, and it would (probably) have resulted in the referee clarifying the rules without penalty to either fencer. But because Kharlan left the piste without tapping blades and without shaking hands, it left an opening for Smirnova to exploit.
I do wish that the FIE would go on record saying whether the handshake rule is fully back in effect. I'm actually a fan of tapping blades, because too many fencers show up to tournaments sick, and shaking hands with everyone is a good way to spread disease. Even beyond that, people often have very sweaty hands, and it's just kinda gross.
