Such directives are considered imperative, and are enforced by disciplines within the Party, as all media in China are required to be loyal to the Party, and are to serve as propaganda organs for the Party in principle. Operational and reporting freedom has significantly increased in the Chinese media in the recent decade. However, open defiance against the Publicity Department directives is rare, as dissenting media organizations risk severe punishment, including restructuring or closure. In 2000, a system of warnings was introduced for individual journalists, whereby repeat offenses can lead to dismissal. Chinese journalists disclosing Publicity Department directives to foreign media may be charged with "divulging state secrets."
