BEIJING -- China on Friday started soliciting public opinion on a draft guideline for the development of national data infrastructure amid the country's efforts to boost digital economy growth.

The country expects to complete the building of the main structure of the national data infrastructure by 2029, according to the guideline, published by the National Data Administration to solicit public opinions till Dec 1.
