Apple CEO Tim Cook had nothing but high praise for Didi Chuxing CEO Jean Liu in an exert he wrote about her for Time magazine.

Liu was named one of Time’s 100 most influential people of 2017. Cook, who sits on Didi’s board, was asked to write about Liu and said that her taxi-hailing startup is changing how people in China connect and commute with its convenience and flexibility.

Apple CEO Tim Cook is currently on another tour of China this week and is staying busy by visiting some of the hottest startups in the country.

This morning Cook paid a visit to bike-sharing startup Ofo which is already valued at $1 billion and counts Uber-rival/Apple-ally Didi Chuxing as one of its investors.

Apple has scored a seat on the board of Didi Chuxing, the Chinese Uber rival that Apple invested $1 billion in earlier this year.

Although Didi Chuxing denied it at the time, regulatory filings show that Apple took the board position in late June, one month after it made its generous investment — designed to aid Apple’s continued push into China and interest in shaking up the automotive industry.

The second largest ride-hailing service in the U.S., Lyft, has reportedly been trying to find relief from its fierce competition by approaching Apple and other top tech companies regarding a possible acquisition.

Apple’s decision to invest $1 billion in “Chinese Uber” Didi Chuxing earlier this year is proving a smart move after the company bought out the real Uber in China — bringing an end to what was proving to be a costly and bitter battle over the Chinese lift-sharing market.

Tim Cook is in China again, and he marked the occasion by paying a visit to an Apple Store in Beijing on Monday — in the company of Liu Qing, a.k.a. the president of Didi Chuxing, the Chinese Uber rival Apple just invested a staggering $1 billion in.

Apple has invested $1 billion in Chinese Uber rival Didi Chuxing in a move that continues Apple’s push into China and confirms the company’s interest in shaking up the automotive industry.

According to Tim Cook, the deal “reflects our excitement about their growing business … and also our continued confidence in the long term in China’s economy.” Perhaps more importantly, it could give Apple strategic insights and competitive advantages when it comes to Apple Pay and a possible Apple Car.
