THE Government will talk to China about allowing mainland passport holders to travel to Hong Kong without the need for visas. Secretary for Security, Alistair Asprey, yesterday said the Government was planning to raise the issue with the mainland. At present, mainland visitors holding two-way permits and those in transit can stay in Hong Kong for seven days without a visa. Mr Asprey also said the Government planned to introduce machine readable permits for Taiwan visitors at the end of this year to reduce processing and clearance time. It also intended to accept applications for visit visas direct from overseas applicants in mid-1995. He noted the visa policy was reviewed regularly, having regard to 'our political, economic and security factors'. But despite repeated questions from legislators, Mr Asprey did not detail what political factors were being considered. He said the Government intended to review the present requirements for certain Middle East countries such as Lebanon. He admitted that the processing time for applications from Middle East nationals - whose countries failed to control terrorism - lasted as long as six months. That was because the Government had to seek information from overseas.
