By maintaining constant relationships with top U.N. leaders, ASD is spreading the most influential activities in the international community.

ASD participates in the main committees of the UN HLPF, UN ECOSOC, and formal meetings with key UN leaders to expand the SDGs global network.

In 2012, 2014, and 2016, the association visited former UN Secretary-General Ban Ki-moon and former Deputy Secretary-General Jan Eliasson at the UN Headquarters in New York. During the 70th session of the UN General Assembly (2015) of which the UN SDGs were first established, former Deputy Secretary-General Amina J. Mohammed met with the association separately. In 2016, ASD had a conversation with the Special Adviser of the UN Secretary-General on the 2030 Agenda for Sustainable Development and Climate Change David Nabarro. In July of 2019 during the UN HLPF, the association hosted an official meeting with the UN Assistant Secretary-General & Chief Economist at the UN Department of Economic and Social Affairs Elliott Harris at the New York UN Headquarters to discuss the SDGs strategies and activities of the association.

The activities of the association have been introduced and discussed at the 72nd session of the UN General Assembly (2018) by the Seventy-second President of the General Assembly H.E. Mr. Miroslav Lajčák and the Seventy-third President of the Economic and Social Council H.E. Ambassador Marie Chatardová.
