(Monaco) -- The International Olympic Committee is announcing some radical changes to the games.

At this week's meeting in Monaco, the IOC approved a measure allowing future countries hosting the games to stage events in different cities and even countries. That decision could first impact the 2018 Winter Games in South Korea, where sledding events could be moved to Europe, Canada or the U.S.

The committee then voted to throw out the 28 total sports cap for the Summer Olympics, instead opting to limit the number of athletes and events. That would pave the way for the return of baseball and softball in the 2020 Summer Games in Japan.

The rule changes also allow a joint U.S. bid for the 2024 Summer Olympics. Los Angeles and San Francisco could submit a joint bid to host the games.
