Do foreign universities have correspondence education, that is, you can get a diploma from a foreign university without going abroad?
I don't think so. It wants to run a school in China, and may enroll students in the form of running a school jointly with domestic universities (there are many such forms in China, and there is also a major called business administration-Sino-British cooperation. Some certificates obtained after graduation are recognized in the UK, such as the Cambridge Business Administration Certificate. But the diploma is issued by the National Self-taught Examination Committee).
