The International Olympic Committee said Wednesday that Tokyo will not be penalized for Gov. Naoki Inose's disparaging comments about Istanbul's bid for the 2020 Olympics.

"We wrote to Tokyo 2020 to remind them of the rules of conduct and this concludes the matter," an IOC spokesman said.

The IOC asks all bidders to "refrain from any act or comment likely to tarnish the image of a rival city or be prejudicial to it. Any comparison with other cities is strictly forbidden."
