Individual athletes from North Korea who qualify to compete in Beijing could still be accepted by a separate decision in the future, Bach said.
The suspension marks a steep drop in North Korea’s Olympic status since the 2018 Winter Games in South Korea, where the International Olympic Committee tried to aid a diplomatic breakthrough.
Athletes from the Korean neighbours marched together in the opening ceremony at Pyeongchang and joined together in a women’s ice hockey team.
North Korea withdrew its team in April from the Tokyo Olympics citing a need to protect athletes from the “world public health crisis caused by COVID-19.”
“They were violating the Olympic Charter and did not fulfill their obligation as stated in the Olympic Charter to participate,” Bach said at a news conference after an IOC executive board meeting.
The North Korean Olympic committee is suspended through 2022 and the exclusion could be extended, he said.
North Korea sent 10 competitors to the 2018 Winter Games, none in 2014 at Sochi, Russia, and two to Vancouver in 2010.
Asked what the IOC’s message would be to countries like North Korea and Afghanistan – where women risk losing the right to play sports – Bach said taking part in the Olympics can “show to the world how it could look like if everybody would respect the same rules, if everybody would live together peacefully without any kind of discrimination.”
Bach had earlier talked about the IOC supporting efforts to help athletes and officials leave Afghanistan with humanitarian visas and extending financial help for the country’s potential Olympic competitors.
After twelve days of jam-packed action, the (Summer) Paralympic flag has been handed to Paris, the 16th Paralympic Games declared closed, and the Paralympic flame extinguished, also bringing to an end over six weeks of spectacular sporting action in Tokyo.
