Jeremić is the youngest person ever to have served as President of the United Nations General Assembly. His tenure saw Palestine granted non-member observer status in the General Assembly, the General Assembly's adoption of the Arms Trade Treaty (ATT), which aimed to regulate international conventional weapons commerce, and the proclamation of 6 April as the International Day of Sport for Development and Peace. Jeremić describes himself as a "fervent, pro-European politician". He is the current president of the Center for International Relations and Sustainable Development (CIRSD) and editor-in-chief of "Horizons", an English-language global public policy magazine. Jeremić was a candidate in the race to succeed Ban Ki-moon as United Nations Secretary-General in 2016, finishing second overall, behind eventual winner António Guterres. He unsuccessfully ran in the 2017 Serbian presidential election as an independent candidate. In October 2017, he founded the center-right People's Party.
