Overall revenue generated by China's publishing industry has grown by more than $100 billion (92.6 billion euros; 80.8 billion) since 2011, partly as a result of international collaboration, according to figures released at the London Book Fair on March 15.

They show China's publishing industry's revenue grew to $315.5 billion in 2015, from $212.2 billion in 2011.

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.

Xiang Xiaowei, minister counselor for culture at the Chinese embassy in the United Kingdom, says publishing-industry synergy is a highlight of Sino-UK collaboration.

Globally, China has been featured at 17 major international book fairs. The Beijing International Book Fair is also becoming a key international book fair.

Speaking about the future, Zhu Weifeng, a director at the State Administration of Press, Publishing, Radio, Film and Television, says: "In the past, Chinese and overseas publishing-industry collaboration was focused on traditional methods, such as rights trading ... but now collaboration in the digital-publishing space is also growing."

Meanwhile, many international publishers are engaging in China-related activities.

One example is London-based ACA Publishing, which has bought the rights to several Chinese books for translation into English. They cover a range of subjects, including biographies, economics, culture and politics.

ACA bought the rights to 20 Chinese books so far this year.

Publisher Wang Ying says: "I see engaging with China-themed books as a sunrise opportunity within the publishing industry."
