Overall revenue generated by China's publishing industry has grown by more than $100 billion since 2011, partly as a result of international collaboration, according to figures revealed at the London Book Fair on Wednesday.

They show China's publishing industry's revenue grew to $315.5 billion in 2015, from $212.2 billion in 2011. In 2016, China's book-retail market grew to $10.1 billion.

The figures were published in a report launched at the 2017 International Publishing Forum of the London Book Fair, a seminar attended by around 100 Chinese and international publishers. Key topics include Chinese and international publishers' expansions into each other's markets, the trading of book copyrights, translation, and joint development of books and digital content.

"This report helps international publishers understand China's publishing market and identify market opportunities," says Mao Yuansheng, president of International Publishing Journal.

Jacks Thomas, director of the London Book Fair, says books are an important way in which people can learn more about China's fast-changing landscape.
