KYIV, UKRAINE • With next year’s Paris Olympics on the horizon and Russia’s invasion looking more like a prolonged conflict, Ukraine’s sports minister on Friday renewed a threat to boycott the games if Russia and Belarus are allowed to compete and said Kyiv would lobby other nations to join.

Such a move could lead to the biggest rift in the Olympic movement since the Cold War era.

No nation has declared it will boycott the 2024 Summer Games. But Ukraine won support from Poland, the Baltic nations and Denmark, who pushed back against an International Olympic Committee plan to allow delegations from Russia and ally Belarus to compete in Paris as “neutral athletes,” without flags or anthems.

“We cannot compromise on the admission of Russian and Belarusian athletes,” said Ukrainian Sports Minister Vadym Huttsait, who also heads its national Olympic committee, citing attacks on his country, the deaths of its athletes and the destruction of its sports facilities.

A meeting of his committee did not commit to a boycott but approved plans to try to persuade global sports officials in the next two months — including discussion of a possible boycott.

Huttsait added: “As a last option, but I note that this is my personal opinion, if we do not succeed, then we will have to boycott the Olympic Games.”

Paris will be the final Olympics under outgoing IOC head Thomas Bach, who is looking to his legacy after a tenure marked by disputes over Russia’s status.

Bach’s views were shaped when he was an Olympic gold medalist in fencing and his country, West Germany, took part in the U.s.-led boycott of the 1980 Olympics in Moscow over the Soviet invasion of Afghanistan. He has condemned that decision ever since.

Russia has cautiously welcomed the IOC’S decision to give it a path to the Olympics but demands it drop a condition that would leave out those athletes deemed to be “actively supporting the war in Ukraine.”

Russian Olympic Committee head Stanislav Pozdnyakov, a teammate of Ukraine’s Huttsait at the 1992 Olympics, called that aspect discriminatory. The IOC, which previously recommended excluding Russia and Belarus from world sports, now argues it cannot discriminate purely based on citizenship.

The leaders of Estonia, Latvia and Lithuania urged the IOC to ban Russia.

“I think that our efforts should be on convincing our other friends and allies that the participation of Russian and Belarusian athletes is just wrong,” Estonian Prime Minister Kaja Kallas said. “So boycotting is the next step. I think people will understand why this is necessary.”

The IOC said “this threat of a boycott only leads to further escalation of the situation, not only in sport, but also in the wider context. It is regretful politicians are misusing athletes and sport as tools to achieve their political objectives.”

It added bluntly: “Why punish athletes from your country for the Russian government starting the war?”

Poland’s sports minister Kamil Bortniczuk said as many as 40 countries could jointly condemn Russian and Belarusian participation at Paris in a statement next week but it could stop short of a boycott threat.
