2024 Paris Olympics

Paris Mayor Anne Hidalgo waved the flag which she was handed in Tokyo during the handover ceremony as she stepped out of the aircraft bringing home some of the country's last athletes.

The 2024 games would be "something very positive for our country. They come at a good moment," Hidalgo said.

Paris she said had learned many lessons from Tokyo's experience.

Delayed by a year and upended by strict COVID-19 countermeasures as contagious variants surged back around the world, the 2020 Games fell short of the triumph and financial windfall Japan had wanted.

All four sports were proposed by Paris organisers in February, while breakdancing and sport climbing both appeared as medal events at the Youth Olympic Games in Buenos Aires last year.

Skateboarding, climbing and surfing will make their Olympic debuts at Tokyo 2020.

"The four sports that Paris has proposed are all totally in line with Olympic Agenda 2020 because they contribute to making the programme more gender balanced and urban, and offer the opportunity to connect with the younger generation," said IOC president Thomas Bach.
