All the so-called 2+2 exchange programs signed between universities and foreign universities are approved by the Ministry of Education, and the diplomas and knowledge obtained by the other universities are recognized by the Ministry of Education. This kind of diploma is mainly an undergraduate diploma (there is no such thing as a junior college diploma at present). The exchange program between China Renmin University and foreign universities, especially the one you mentioned, is definitely an undergraduate exchange program, which has been recognized by the Ministry of Education. There is no problem that the first degree is a junior college. Renmin University and dozens of foreign universities have such exchange programs, which basically belong to the top universities in various countries. Generally speaking, this exchange plan of major universities also emphasizes the principle of reciprocity, and a good university is also a good university corresponding to a foreign university.
