The National Association of Financial Market Institutional Investors (NAFMII) launched the social and sustainability bonds pilot program in 2021. The program has received widespread attention and positive comments from home and abroad. At the invitation of the United Nations Development Programme (UNDP), NAFMII and UNDP jointly wrote and released "Issue brief-Pilot of Social and Sustainability Bonds on China’s Inter-Bank Market" . Both sides hope that the Brief will enable other markets, including developing countries, to better understand China's exploration and practice in promoting social bonds and sustainability bonds. UNDP encourages all parties around the world to actively participate and strengthen cooperation to help achieve the sustainable development goals.
