The Chinese Ministry of Public Security makes a decision based on a case by case basis whether or not you will be granted a visa to China or not.
That being said, certain countries have been identified as being associated with terrorist activities - those country citizens might be denied a visa to enter China. Thus people born in the African and Middle Eastern countries might expect delays or face denied applications.
This restriction will be applied to all visas released by the Embassy, the Consulate and the Ministry of public security itself. They reserve the right to refuse the visa to people born in country reported to be at high terror risk.NOTE: iVisa is not responsible for the final visa decision regarding this and does not offer an refunds.
