According to the bilateral agreements or agreements signed or concluded between China and other countries, certain travelers may enter China without a visa if they meet the preconditions listed in the abovementioned agreement.
As of May 2, 2019, citizens originating from the following 14 countries are authorized to travel to China with ordinary passports without applying for a visa in advance:
The United Arab Emirates, Barbados
Bosnia and Herzegovina, Ecuador, Fiji
Grenada, Qatar, Mauritius
Serbia, Seychelles, San Marino, Tonga
However, do note that the visa-free entry does not mean they are authorized to stay in the country indefinitely. The agreement only allows them to travel within China for no more than 30 days.
Should the traveler require a stay for more than 30 days, he or she should apply for a residence stopover as soon as possible to make sure their prolonged presence in China remains legal.
