China's Communist Party has begun ordering all Chinese journalists not to take supportive stances toward Japan when writing about territorial and historical issues between the two countries, participants of a mandatory training program revealed Saturday.

Around 250,000 journalists who work for various Chinese media organizations must attend the nationwide training program to learn about such topics as Marxist views on journalism, laws and regulations and norms in news-gathering and editing, in order to get their press accreditation renewed. The unified program started in mid-October and will run through the end of this year.

It is believed to be the first time the ruling Chinese Communist Party, which tightly controls the country's media industry, has carried out this kind of training program before renewing press credentials.
