Chief Executive Tung Chee-hwa's expressions of support for a movement to preserve Hong Kong's core values were dismissed yesterday as 'just talk'. 'Our government just confines itself to talking. In our view, doing rather than talking is more important,' said Anthony Cheung Bing-leung, a convenor of the core values movement. Despite promising earlier to consider joining discussions organised by a group promoting values such as freedom, pluralism and social justice, Mr Tung will send only a junior adviser and a principal assistant secretary to a public forum on Sunday afternoon. Lee Ming-kwan, a member of the Central Policy Unit, and Nancy Hui Wu Wan-wan from the Home Affairs Bureau, will listen to the public's views on behalf of Mr Tung. No government ministers will attend, according to Mr Cheung. They were all contacted but they were too busy to attend. 'Some didn't even reply,' he said.
