Government-imposed reforms of school management will allow officials to set an education agenda that will 'brainwash' students, Cardinal Joseph Zen Ze-kiun warned. Zen, the former head of Hong Kong's Catholic Church, has called on teachers and students to resist the government's plan to introduce the agenda at all primary and secondary schools. He called the planned subject 'too vague'. 'What exactly does the subject want to teach? Does national education mean unconditional support for the Communist Party?' Zen said at a forum on the issue by the Catholic Education Office. Zen did not rule out actively opposing the agenda or applying for a judicial review against it. Public consultation on the issue ended on August 31. Critics say the government has failed to provide details about its curriculum. Under the plan, all primary and secondary schools must teach national education as a new subject.
