Theme:「Xin-信」
Literally meaning “message” or “letter,”「Xin-信」represents a primitive means of communication. Today, however, it encompasses many more dimensions than ever before, as illustrated by words such as Xin-xi (information); Xin-nian (vision); Xin-ren (trust); Xin-yong (creditability) and Xin-xin (faith).

In 1972, the UN General Assembly introduced World Development Information Day to draw public attention to development problems and the need to strengthen international cooperation in order to solve them (Resolution 3038). The Assembly eventually decided that this should coincide with United Nations Day on October 24, also the date for the adoption of the 1970 International Development Strategy. October 24 is also the first day of XIN Beijing. Like designers, the General Assembly believed that improving the dissemination of information through communication design and mobilizing public opinion, particularly amongst the younger generation, would lead to greater awareness and cooperation in solving the problems of international development.
