Hugo Barra is leaving his post at Chinese phone maker Xiaomi

Hugo Barra announced Sunday night that he plans to step down as head of international efforts for Xiaomi, the once fast-growing Chinese phone maker.

Barra, who joined Xiaomi from Google in 2013, said in a post on Facebook that he plans to return to the U.S. and will remain an adviser to Xiaomi.

“As I thought about this late last year, I concluded that Xiaomi is in a very good place on its global expansion path, and if there was ever going to be a good time for me to come back home, that time is now — when I can confidently say our global business is no longer just an in-house startup,” Barra wrote.

The Chinese company has seen its growth slow in its home market and, while it built up a sizable business in India, has also struggled to duplicate the success it enjoyed in China.

In a recent annual letter, Xiaomi Chairman Lei Jun highlighted the company’s progress in India, but also described 2016 as “a year in which we took time to catch our breaths and slow our rapid pace to make essential adjustments to our business that will enable us to go further.”

Barra said he plans to leave Xiaomi in February, after the Chinese New Year. “I will take some much-needed time off before embarking on a new adventure back in Silicon Valley.”

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
