The development of a coronavirus vaccine or treatment will be key to allowing the postponed Tokyo 2020 games to open in a year's time, organising committee president Yoshiro Mori said Wednesday. Asked what factors will be crucial for the rescheduled Games to go ahead, Mori said "it would be whether the coronavirus woe is settling down." "Specifically, the first point will be that a vaccine or drug has been developed," he said in an interview with national broadcaster NHK, published Wednesday. Asked whether Tokyo could hold the Games if the virus situation remained unchanged, Mori said: "If things continue as they are now, we couldn't." But he said that scenario was hypothetical.

"I can't imagine a situation like this will continue for another year," he said Tokyo 2020 should have been opening on Friday, but the Games were postponed in March as the coronavirus spread across the globe, marking the worst disruption to an Olympics since two editions were cancelled during World War II.
