In December 2010, Stefanović was appointed by president Boris Tadić as Serbia's representative for the Belgrade-Pristina negotiations. In July 2011, Blic reported that Serbia's Minister of Foreign Affairs Vuk Jeremić attempted to replace Stefanović in his position in the Belgrade-Pristina talks. Jeremić sought to completely remove the Ministry of Foreign Affairs of having any participation in the talks, allegedly saying that his Ministry and the negotiations "have contradicting goals". However, according to Blic's sources, Boris Tadić did not approve Jeremić's removal of Stefanović from Serbia's negotiation team on Kosovo. On top of the allegations of Jeremić's attempt to remove Stefanović from the Kosovo talks, Stefanović was Jeremić's best man at his wedding. In September 2011, Jeremić replaced Stefanović as chief of staff of the MSP with Serbia's former ambassador to Slovakia, Danko Prokić.
