In accordance with the principle of “combining full-time and part-time teaching and giving priority to the latter” and the philosophy of “diplomats teaching diplomacy”, the China Diplomatic Academy actively strengthens the teaching workforce. Every year it selects more than 350 instructors from the Foreign Ministry, among which 42 percent are senior diplomats including department-level and bureau-level officials as well as ambassadors and counselors, and more than 53 percent are division officials and mid-level officials, which ensures that the training is politically-oriented, authoritative, instructive and targeted. At the same time, it actively recruits excellent teachers at home and abroad to engage in the training and invites well-known experts and scholars to give lectures to key classes, so as to continuously improve the authority of teaching.
