International Olympic Committee President Thomas Bach has told athletes they should travel to Tokyo with "full confidence" that the delayed 2020 Games will be safe for competitors and not jeopardize the health of Japan's residents.

Speaking in a Q&A session during an online conference of the Athletes' Commission on Thursday, Bach said the safety of athletes was at the heart of the planning for the games, which are scheduled to run from July 23 to Aug. 8.

"Tokyo is the best prepared Olympic city ever and this relates particularly to the focus they are putting on the athletes and the athletes' experience," the German told around 2,000 athletes and Olympic officials from Lausanne.
