The ban was originally imposed after the Russian invasion of Ukraine in February but was due to expire at the end of 2022.

A meeting of the WCF Board has voted to extend the ban after after concerns were raised over the participation of Russia and Belarus.

"Their involvement would damage the integrity of the events due to the ongoing conflict in Ukraine," a WCF statement said.

The extension was granted under WCF Rule C1(b) which includes a clause allowing the international governing body to take action.

"The Board of the WCF may remove a team or Member Association from any WCF event if in the sole opinion of the Board their presence at the event would damage the event or put the safety of the participants or the good order of the event at risk," the rule states.

The WCF Board have said that they are continuing to monitor “Member Association and athlete concerns relating to the conflict,"

World Curling had earlier stripped hosting rights for the 2022 European Championships from Perm in Russia and moved the event to Östersund in Sweden. 

The extended ban will now encompass the 2023 World Championships.

These include the wheelchair event in Richmond in Canada, scheduled to start on March 4, the Women’s World Championships in Sandviken in Sweden, due to begin on March 18, and the men’s edition in Ottowa, set to open on April 1, and the mixed doubles at the Olympic rink in Gangneung in South Korea, expected to begin on April 23.

The WCF indicated that they will "revisit" the decision if this proves necessary.
