North Korea's 2018 Winter Games delegation.

LAUSANNE: The IOC punished North Korea's Tokyo Games no-show by suspending their National Olympic Committee until the end of 2022, Olympic chief Thomas Bach announced on Wednesday.

The suspension covers the upcoming Beijing Winter Olympics.

"The NOC of the People's Republic of Korea was the only NOC not participating in the Olympic Games Tokyo 2020. The IOC executive board decided to suspend the NOC until the end of 2022, as a result of this unilateral decision," Bach told a press conference.

North Korea were the only one of over 200 NOCs not to participate in the delayed 2020 Games in Japan.

As a result they violated one of the Olympic Charter's main tenets that "each NOC is obliged to participate in the Games of the Olympiad by sending athletes".

Their refusal came after rejecting all of the IOC's proposals over coronavirus safety protocols "until the very last minute including the provision of vaccines" an IOC statement pointed out.

It said the North Koreans had received clear warnings about the consequences of carrying out their first boycott of a Summer Games since Seoul in 1988.

Bach said if a North Korean athlete qualifies for Beijing the IOC would take "an appropiate decision in due course".
