The risks were detailed in the Handbook of Country Risk 2020, released on Thursday by China Export and Credit Insurance Corporation, or Sinosure, China's policy-oriented insurer.

A handbook that dictates a "single Airbus code" will be finalized this summer and distributed in September.

For instance, a handbook to guide children's sports with professional institutions that is sponsored by the China Charity Federation-BMW Warm Heart Fund will be released in the second half of this year.

In addition, BMW has written a handbook to guide children's sports with professional institutions, and donated 300 copies to the schools.

Alibaba founder Jack Ma has donated massive quantities of surgical masks and test kits to a number of countries, and has been promoting a digital handbook on the experiences of front-line Chinese medical workers in screening, diagnosing and treating COVID-19 patients.

"I need your help to share this handbook quickly with hospitals, doctors, nurses and anyone who needs to know around the world," he said in a Tweet, followed by a link to the manual on Alibaba Cloud.

The Handbook of Country Risk, an annual report first published in 2005, has become an important reference for Chinese companies investing overseas.

"The annual handbook by Sinosure is an important guidance for us in avoiding risks overseas or when we are looking for new market opportunities," said Wang Lijun, vice-president of China Road and Bridge Corporation.
