Cheng Wei is very much the face of new China.

He's quietly confident, with the conviction to carry out what he wants to achieve. And he's got the cash to splash on ambitious plans for the future.

"This is not old China. This is a new generation, " says Chris DeAngelis, who routinely advises Western companies coming into China.

"The US needs to wake up because right now, we're going to get our asses kicked basically," adds Chris, speaking of the prowess that Chinese tech firms such as Didi have over American ones.

But Cheng Wei isn't losing any sleep over the US-China rivalry.

"For the past two decades, it was China who learned more from the US," he says. "But in the next 10 years, we'll ride on each other's successes. There's no point thinking who will surpass who."

Watch out world, Didi is coming.
