Responding to the “The Phnom Penh Agenda 2012” which called for a comprehensive Mid-term Review (MTR) of the IAI Work Plan II, this study has been commissioned to stock-take the implementation of the IAI Work Plan II; map the Work Plan with other sub-regional, multilateral and trilateral development projects/programs; set out concrete and practical measures to expedite the implementation of Work Plan II; and recommend its future direction. The review was timely and important for the future direction of the IAI.
