Formula One boss Chase Carey has outlined the criteria potential grand prix venues must meet in order to make it on the championship's race calendar.
Carey was installed as F1 CEO when Liberty Media's takeover was completed at the start of 2017. While Liberty insists it is committed to preserving races in F1's European heartland, it is also looking at ways to expand in key markets -- notably in Asia and North America.
The city of Miami recently approved plans to host a grand prix and is currently negotiating the terms of the 10-year deal with F1, while Vietnam appears to be edging closer to hosting a race in 2019 or 2020.
