During a meeting at the Portuguese unit of Macao's public broadcaster TDM on March 10, two senior journalists addressed about 25 staff, reading new editorial rules requiring them to promote "patriotism, respect and love" for mainland China.

The measures targeting Macao's largest broadcaster were detailed by two people who were at the meeting and mark the first time that Portuguese-language media in the former colony have been directly targeted by authorities.

Since the meeting, at least six journalists have resigned, the sources said.
