Mainland officials have no grounds to bar Hong Kong citizens from entering the mainland without an explanation, a pro-democracy alliance claimed yesterday. Secretary for Constitutional Affairs Michael Suen Ming-yeung was also criticised for failing to act for citizens in seeking an explanation. Eight people were known to have been refused renewal of their re-entry permits, while 10 were refused entry but allowed to keep their permits. Another 12 people had their permits taken back. Among those blacklisted were Democratic legislators Andrew Cheng Kar-foo, Albert Ho Chun-yan and party chairman Martin Lee Chu-ming. After a third meeting with Mr Suen, Mr Cheng said: 'He was acting as if he was just a messenger . . . not daring to offend the central Government.' Szeto Wah, chairman of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, said Mr Suen was said to have met a Hong Kong and Macau Affairs Office official. Mr Suen refused to identify the official, saying only he was given a booklet on exit and entry rules for PRC citizens. He was unable to explain the relevant section under which these people were barred, Mr Szeto said. 'We have read the relevant section and I doubt if the rules apply to us,' he said. Mr Suen said PRC officials informed him they were not obliged to tell a third party the reasons for refusing entry, Mr Szeto said. Those refused would have to enquire in writing to the Guangdong Security Bureau.
