Qiushi, the Communist Party journal, issued an article as part of a series of commentaries regarding Hu Jintao’s speech on Party propaganda. The article states that media must primarily provide positive publicity, shall never publish any opinion contrary to the spirit of the Party’s viewpoints, and shall never provide channels for spreading “noises.”
