Lyft and Uber have been rivals for many years, which is why Lyft’s partnership with Chinese company Didi Kuaidi was made all the sweeter. The two companies struck a deal in 2015, joining forces to share riders at home and overseas.

Didi put in $100 million in a bid to help both companies become stronger in the battle against Uber. Interestingly, Didi is backed by Tencent and Alibaba, making it a force to be reckoned with in China already. At the time, Didi had triple the presence in China as Uber did, making it a super strong contender.
