17 bilateral members work alongside five multilateral members to advance the principle of aid effectiveness in Tanzania. Having being involved in the development process over the course for many years (some since Tanganyika became independent in 1961), bilateral members have acquired an extensive knowledge of the development dynamics in Tanzania and they bring to the table an invaluable contribution of how to further deepen the impact effect of aid assistance in the country. As well as being major funders they help shape development policies and aid frameworks and give technical guidance on the implementation process with a view of making aid more effective and reflective of the aspirations of the people of Tanzania.

DPG is open to any interested bilateral partners, and over the past years, China, Brazil, Israel and New Zealand have participated in some of the DPG meetings and seminars.
