Foreigners with a valid passport, visa and related certificate are required to enter China through designated ports. All persons and personal belongings are subject to quarantine inspection and a frontier inspection upon entering. The quarantine inspection checks for certain sicknesses and diseases in order to prevent possible epidemics, which doesn't pose a problem for most visitors. However, those who come from disease-infected areas are required to present a valid certificate against known diseases in that area. During the frontier inspection, foreigners must present a valid passport, visa and certificate and a completed Entry and Exit Card for approval to enter.
