Tokyo doubles gold medallist Andrey Rublev and fellow tennis players Darya Kasatkina and Anna Kalinskaya are among the 12 Russians and Belarusians who have turned down invitations to compete as neutral athletes at the Paris Olympics.

The International Olympic Committee (IOC) published an updated list of neutral athletes on Monday with 2021 US Open tennis champion Daniil Medvedev and women's world No. 22 Ekaterina Aleksandrova among the 31 who had accepted.

Athletes from Russia and Belarus, Moscow's closest ally in the 2022 invasion of Ukraine, are barred from the Paris Games except for the few who will compete as neutral athletes without flags or anthems.

The athletes have been carefully vetted by an IOC panel to ensure they have no connection to the military.

Russia has denounced the restrictions as discriminatory. Foreign ministry spokeswoman Maria Zakharova has said the IOC was slipping "into racism and neo-Nazism".

World No. 6 Rublev, women's world No. 12 Kasatkina and No.18 Kalinskaya declined along with Tokyo singles silver medallist Karen Khachanov and Liudmila Samsonova, who had already turned down the opportunity to play.

US-based Belarusian Victoria Azarenka, who won a doubles gold and singles bronze in London in 2012, has accepted an invitation but Australian Open champion Aryna Sabalenka has not yet accepted or declined.

The Belarusian world No.3 pulled out of Wimbledon because of a shoulder injury on Monday and Russian Tennis Federation chief Shamil Tarpishchev said last month that Rublev would be skipping the Games for health reasons.

Gymnast Ivan Litvinovich, who won gold for Belarus in the trampoline in Tokyo three years ago, and Russian canoeist Alexey Korovashkov, a bronze medallist in London, were also among the athletes who have accepted the IOC's invitations.

The Paris Olympic Games will run from July 26 to August 11 with the tennis tournament being held from July 27 to August 4 at Roland Garros, the home of the French Open.

The IOC had invited eight top Russian tennis players and Sabalenka and Azarenka from Belarus to compete as neutral athletes.

Tennis is the latest of the Olympic sports to have invitations to Paris confirmed as part of a vetting process to let some athletes from Russia and its military ally Belarus compete with neutral status in individual sports.

Russia and Belarus are excluded from team sports at the Paris Games. It is still unclear how many Russian athletes will compete at the Olympics. They will also not be allowed to take part in the opening ceremony parade of athletes.
