The Chinese government has stopped renewing press credentials for foreign journalists working for American news organizations in China and has implied it will proceed with expulsions if the Trump administration takes further action against Chinese media employees in the United States, according to six people with knowledge of the events.

The actions and threats raise the stakes in the continuing cycles of retribution between Washington and Beijing over news media organizations. Those rounds of retaliation are a prominent element of a much broader downward spiral in U.S.-China relations, one that involves mutually hostile policies and actions over trade, technology, educationdiplomatic missionsTaiwan and military presence in Asia.

American news organizations immediately affected by China’s latest actions include CNN, The Wall Street Journal and Getty Images. Journalists from all three organizations tried to renew press cards with the Foreign Ministry last week, but were told the cards, which are usually good for one year, could not be renewed. In total, at least five journalists in four organizations have been affected, several reporters said.

One journalist said Foreign Ministry officials told him that his fate depended on whether the United States decided in the fall to renew the visas of Chinese journalists working in America who are under new visa regulations imposed by the Department of Homeland Security in May. Other journalists have received similar messages.
