Travelers holding multiple visa entries which were approved after 27 Mar’08 had their multiple visa cancelled and amended to single entry by the immigration at the airport upon arrival. They will need to re-apply for a new visa for their subsequent trips to China.Passengers are strongly advised to apply a business visa to enter China if they are going for business trips.
