Uncork the champagne, because it's raining cash for mobile app developers in China.

Apple's chief marketing officer Phil Schiller reportedly revealed during his China visit that Apple has allocated USD5 billion App Store profit share to Chinese developers.

According to reports in Chinese local media, he also said that many of the most downloaded applications in the App Store were created by Chinese developers.

During Apple's earnings conference held in October 2015, the company disclosed that the number of developers in China topped over one million. Schiller mentioned this figure at an interview again and said Chinese developers' achievement is unprecedented.

So far, Chinese developers have launched 270,000 apps in the App Store. Among the top downloading locations around the world, App Store's operating revenue in China ranked third, following the U.S. and Japan.

Apart from the App Store business, Schiller revealed the company's retail store expansion plan in Greater China. He said that there were five new Apple Stores opening in January 2016, covering cities like Shenyang, Nanjing, Xiamen, and Guangzhou.
