Tsimanouskaya defected to Poland at the delayed Games in the Japanese capital having alleged she was taken to the airport against her will, which forced her to miss her women's 200 metres race, following public criticism of the Belarusian national team's coaches.

She received a humanitarian visa from Poland and is now a full Polish citizen.

World Athletics rules usually require an athlete to undergo a three-year waiting period to change their national allegiance at its competitions, but the Nationality Review Panel has agreed to waive this in Tsimanouskaya's case.

"The National Review Panel agreed to waive the three-year waiting period starting from the date of application [June 12 2023] on the basis the athlete last represented {Belarus} on 30 July 2021, at the Olympic Games, Tokyo, and that the athlete has not competed in national representative competitions for two years," a letter from the Panel reported by Reuters said.

Tsimanouskaya, a former Universiade 200m champion and two-time European Games medallist, has expressed her hope on Instagram she can be selected for this month's World Athletics Championships in Budapest.

"I'm extremely happy but I'm experiencing strange emotions because everything has happened so fast and suddenly," she said.

Belarus, along with Russia, remain banned from World Athletics events because of the war in Ukraine, despite the International Olympic Committee (IOC) updated recommendations allowing their athletes to compete as individual neutrals if they do not support the conflict and are not affiliated to the military.

Tsimanouskaya claimed earlier this year she had received "zero" support from the IOC since Tokyo 2020, but it insisted she had been supported by "the Olympic Movement, represented by the Polish National Olympic Committee (NOC) and the Polish Athletics Federation".

The IOC has confirmed Tsimanouskaya is eligible to compete for Poland at Paris 2024.

"In view of the above and of the applicable rules of the Olympic Charter (in particular Rule 41), the IOC can confirm that Ms Krystsina Tsimanouskaya would be eligible to represent Poland at the Olympic Games Paris 2024 without any further formalities, subject, of course, to qualification and entry by the Polish NOC," it told insidethegames.

"The IOC wishes Ms Tsimanouskaya the very best of success in her career."

Two Belarusian coaches had their accreditations revoked at Tokyo 2020 following the incident involving Tsimanouskaya.

Head coach Yury Maisevich was charged by the Athletics Integrity Unit earlier this year with acting without integrity and in bad faith, but team official Artur Shumak faced no further action.

IOC President Thomas Bach described the incident at Tokyo 2020 as "deplorable".

There are long-standing concerns over the safety of opponents including athletes to Belarusian President Alexander Lukashenko's regime.

The IOC does not recognise the 2021 election of Lukashenko's son Viktor Lukashenko to succeed the head of state as President of the NOC of the Republic of Belarus, but it has avoided suspension.
