The Asian Development Bank (ADB) is a regional development bank to
promote social and economic development in Asia. The bank is headquartered in
Metro Manila, Philippines, and maintains 31 field offices around the world.
The bank was established on 19 December 1966 and admits the members of the UN
Economic and Social Commission for Asia and the Pacific (UNESCAP, formerly the
Economic Commission for Asia and the Far East or ECAFE), and non-regional
developed countries. Starting with 31 members at its establishment, by 2019
ADB had 69 members.
The ADB was modeled closely on the World Bank and has a similar weighted
voting system, where votes are distributed in proportion with members' capital
subscriptions.
