Uber's China division just secured new funding that values the arm at $7 billion.
But it's going up against the homegrown Didi Kuaidi service, which closed a $16 billion valuation last year to serve its native Chinese market.
And to hear Didi tell it, it's dominating in China.
But Didi says it had over 1.4 billion rides in 2015 alone.
To be fair, those rides spread out across private cars (like those Uber offers), taxis, carpooling, buses and even a designated-driver service.
The endgame, of course, is control of China's collective ride-hailing needs. That's where these huge numbers gain more context.
Didi's president tells Re/code the company's diversity and familiarity with the Chinese market will help it win out — regardless of the billions Uber pours into the country.
