In 2009, the Regional 3R Forum in Asia was established at Japans proposal as a platform for wide-ranging cooperation on promotion of the 3Rs reduce, reuse and recycle in Asia. The forum consists of central governments, international agencies, aid agencies, private sector entities, research bodies, NGOs and other relevant parties. Forum members have held high-level discussions on policies, provided support for the implementation of 3R projects in member countries and shared useful information, and are building networks for the further promotion of the 3R initiatives. Japan hosted the inaugural Regional 3R Forum in Tokyo in 2009, and has co-sponsored subsequent Forums together with the governments of host countries and the United Nations Centre for Regional Development (UNCRD) (external link). After the fourth forum, the title was changed to Regional 3R Forum in Asia and the Pacific.
The Fourth Regional 3R Forum held in Ha Noi, Viet Nam, in March 2013 adopted the Ha Noi 3R Declaration ‐ Sustainable 3R Goals for Asia and the Pacific for 2013‐2023 . It is a non-legally binding and voluntary document which aims to provide a basic framework for Asia-Pacific countries to develop measures and programs to promote the 3Rs including a set of 3R indicators for monitoring progress. Japan will continue its efforts to expand cooperation with the governments of other countries, international agencies, and other bodies with the aim of building a sound material-cycle society worldwide.
