From Economic Observer Online:
China was poised to classify a batch of key subsidiaries under central government run firms (central-owned firms) as "Not for Sale". The move was aimed to protect the state's control in strategic industries and resources.
Sources from the State-owned assets watchdog--State-owned Assets Supervision and Administration Commission of the State Council (SASAC) revealed to the Economic Observer that the commission would define and publish a list of key subsidiaries of central-owned firms within this year.
Analysts said that it was necessary to strengthen controls on these subsidiaries in their process of restructuring and shareholding reform as many subsidiaries held key assets of their parent central-owned firms.
