He was quoted as saying, "I talk to foreigners and see how they are reacting. The general impression in the last three months is that things are going well for us."
The EU is expected to deliver a progress report on Serbia in April. Mrkic announced a fifth round of talks between Serbian Prime Minister Ivica Dacic and Kosovo PM Hashim Thaci for the middle of this month.
He said there would be more meetings after that one and that Belgrade's goal in the meantime was to honour the obligations in the platform and the resolution on Kosovo adopted by the Serbian parliament.
Mrkic went on to say that at his meeting with Kosovo President Atifete Jahjaga in Brussels today, Serbian President Tomislav Nikolic would show "support for everything all other Serbian representatives are doing" as well as "the unity of the state leadership."
He said the president "certainly won't negotiate because the negotiations are taking their course" and that PM Dacic "had four rounds of negotiations and will have the fifth one in mid-February. The prime minister is negotiating on some issues based on what was adopted by the Serbian Assembly."
Asked if early elections would be called if Belgrade was not given a date for the start of EU entry talks, Mrkic said this question should be put to politicians, that he did not "deal with internal affairs" and that "nobody in the government has raised this question."
