With hundreds of millions of people, low levels of car ownership, really crowded cities, and underdeveloped public transit, China may be Uber’s most important market. CEO Travis Kalanick seems to agree, because he recently announced that the company will be doubling its expansion plans in the country, with Uber now expected to expand to more than 100 Chinese cities over the next year. It’s not going to be an easy expansion, however, as Asia is the only place where Uber isn’t the undisputed king of the ride-sharing market, and it’s going to have to compete with a bunch of local ride-sharing services.
