Before coming to China, we strongly suggest that all foreign experts check with the Chinese consulate to confirm if a visa is required. We would like to emphasize that in the Chinese embassies in some countries, the term 'exchange' does not include academic exchanges. In such cases, a visa is still required for entry into China.
