A number of mainland and exiled Chinese dissidents are beginning to arrive in Hong Kong for fear they will not be allowed to do so after the handover. The latest is exile Shen Tong, a prominent former Beijing student leader who arrived last Saturday, following Chen Yizi and Hou Xiaotian who came earlier in the month. Mr Shen, 29, went to the United States after the Tiananmen Square crackdown and studied at Boston University. 'The Government's open attitude indicates their autonomy in immigration policies. Should the policy not be continued after July 1, clearly it would be [after] intervention from the Chinese Government,' said Albert Ho Chun-yan of the Hong Kong Alliance in Support of Patriotic Democratic Movement in China. It is understood 28 dissidents in Hong Kong will leave for countries that have offered them political asylum by the end of next month. The countries include the US, Canada, Britain, France, Denmark and Finland.
