Sporting bodies and figures around the world have condemned Russia following its invasion of Ukraine, the crisis breaking out on Thursday in the middle of the Beijing Games hiatus.
The incident had immediate effects on sporting events held in Russia or involving its teams. Japan was among a host of nations to pull out of a freestyle World Cup ski cross event being held in Russia, while the 2023 rugby World Cup qualifier between Georgia and Russia in Tbilisi on Sunday was called off.
The Ski Association of Japan said its four-man team pulled out of the World Cup event at Sunny Valley, Russia, and is leaving for safety reasons.
They were among the 55 skiers who did not start with only six, all from Russia, competing. The women's qualification was limited to seven Russian skiers, with entries from 17 other countries not starting.
The International Olympic Committee on Thursday said in a statement that the invasion constitutes a "breach of the Olympic Truce" adopted at the U.N. General Assembly in December, while the International Paralympic Committee said the truce was endorsed "by consensus of all 193 member states and is co-sponsored by 173 member states, including Russia."
According to the IOC, the truce began a week before the Feb. 4 start of the Beijing Olympics and ends a week after the closing of the March 13 Paralympic Games.
"This is a truly horrible situation, and we are greatly concerned about our National Paralympic Committee and Para athletes from Ukraine," said IPC President Andrew Parsons.
"Our top priority right now is the safety and well-being of the Ukrainian delegation, with whom we are in regular dialogue."
Parsons said he spoke with Ukrainian Paralympic Committee President Valeriy Sushkevych and was informed that while Ukrainian Para athletes wish to compete in Beijing, "getting the team to Beijing is going to be a mammoth challenge."
