Starting [Saturday], all media operators, including Internet media companies, face immediate closure if any news articles or comments, which could be deemed a threat to Thailands national security and monarchy, are published.

The Information Ministry invited all companies and operators to discuss cooperation methods in helping the government "to restrict, control, stop or destroy information deemed to affect the constitutional monarchy".

Chief internet inspector Kritpong Rimcharonepak told reporters: "We seek their cooperation not to present articles, remarks, or information that will infringe the democratic reform under the constitutional monarchy. They can still present political comments on their media, but if anything goes wrong, the caretakers of those media must take responsibility."
