The IDF Western Pacific Region (WPR) represents 26 Members in 21 countries and territories and is the largest of the IDF Regions in terms of population and is the most diverse economically, politically and culturally. The members from East Asia, the South-East Asian Peninsula and Oceania, represent a substantial proportion of the Region's population. Steps are being taken to expand the membership and to bring in member associations from those parts of the Region which are less well represented - particularly from the South-East Asian Peninsula and Oceania.

The elected IDF representatives for the Western Pacific Region for 2016-17 are:

Chair: Prof. Wayne H H Sheu, Taiwan
Chair Elect: Prof. Linong Ji, China
