China's top legislature called upon governments at all levels on Monday to strengthen copyright protection by creating an information-sharing system for administrations and judicial authorities, along with a blacklist of violators.

Over the past several years, the country has made efforts against copyright infringement, but more efforts are needed, according to a report on the enforcement of the Copyright Law by a specialized team under the legislature.

The report is being discussed at the bimonthly session of the Standing Committee of the National People's Congress, which ends on Friday.
