China revises draft rules on data security for business sectors

China's industry ministry published revisions to draft rules on Thursday dictating how companies and localities should manage data, bringing more specificity to the country's evolving data governance regime.

The updated rules, which China's Ministry of Industry (MIIT) and Information Technology first published in September, removes a previous statement that "core data," defined as data that poses a "serious threat" to China's national and economic interests, must not leave the country.

In addition, the rules add electromagnetics to the wide range of categories that contain data that could be considered "core data" or "important data."
