Visitors to the mainland of the People's Republic of China must obtain a visa from one of the Chinese diplomatic missions, unless they come from one of the visa exempt countries. The two Special Administrative Regions – Hong Kong and Macau – maintain their own independent border control policies and thus have their own separate visa requirements. Starting from 9 February 2017, holders of non-Chinese travel documents aged between 14 and 70 have been fingerprinted upon entry, with the exception of holders of diplomatic passports.
