The number of UN employees from a nation is determined by that nation’s membership fee, membership and population. The number of UN Chinese employees has increased 7 times in the past 24 years with an increasing number of Chinese employees becoming high ranking UN officials. At the same time, more UN employees from other countries are learning Chinese. This past summer, the United Nations worked jointly with Nanjing University to once again open a Chinese language class. About 50 UN employees joined the class.
