A proposal to grant visa exemptions to Shenzhen citizens visiting Hong Kong will be put to the SAR Government in April, a mainland government adviser said yesterday. Liu Zhanjun, assistant secretary of the China Development Institute - formed in 1989 under the State Council to map out strategic studies in Shenzhen - said a study was under way. It currently takes about a month to process visa applications from Shenzhen people wanting to visit Hong Kong, due to the complexity of procedures, he said. Mr Liu said he expected the number of Shenzhen visitors and business travellers to Hong Kong would double if the plan went ahead. An estimated one million tourists and business travellers visit the SAR from Shenzhen each year, he said. The proposal is one of the topics for discussion at a meeting between Shenzhen and SAR government officials in April, he said. Other major issues would include further talks on 24-hour opening at border crossings.
