Founded in 2009, Yoozoo now owns branches globally, including in the United Kingdom, Germany, Japan, South Korea, India and Singapore.

Attaining nearly 1 billion registered users worldwide, Yoozoo has established a global distribution network covering more than 200 countries and regions. The company said it will continue to develop in regions where it has already gained an edge, such as North America, Europe, Southeast Asia and South Asia. And it will further expand globally, especially in South Korea, Japan and the Middle East.

Yoozoo gained the 11th spot in App Annie's Top 52 Publishers List of 2018 by earnings. The company reported its revenues surged by 10.68 percent year-on-year to 3.58 billion yuan in 2018, more than half of which was gained from overseas markets.

Statistics from App Annie showed mobile game revenues gained from the iOS App Store surged by 4 percent year-on-year in China last year, while the global number hit 13 percent.

Chinese gaming publishers earned $6 billion in overseas markets, with an increase of 49 percent year-on-year, App Annie said.

The US topped all other countries and regions in terms of the largest source of overseas income, followed by Japan and South Korea.

"While the domestic gaming market witnessed slow growth in 2018, Chinese gaming firms have earned a lot in fast-growing overseas markets," said Ren Ning, customer director at App Annie China region. "A growing number of Chinese gaming firms are expanding globally, and the trend will continue this year. As users' habits and tastes differ from country to country, Chinese gaming firms can always find a suitable place to launch their games and expand their business, giving them an equal shot to go global."
