Foreign Minister Margot Wallström is one of four Swedish ministers at the summit in New York. Swedish Radio News reports that she has a packed schedule with more than 40 individual meetings with other countries plus a wide range of speeches and so-called high-level meetings.
Wallström said she will be actively campaigning for Sweden to get a seat on the Security Council.
"This is a very important opportunity to talk to as many countries as possible as to why we have a very good case to take a seat on the Security Council," she said. "We're actually the fifth largest humanitarian aid donor in the world, we are a loyal - albeit critical - friend of the UN. We stand up for and are here for the United Nations as an active member."
The Security Council is the UN's most powerful decision-making body, with a primary responsibility of ensuring international peace and security. Five countries sit on the council as permanent members and there are 10 elected members states who serve 2-year terms.
After approving the new development agenda, Wallström said the next important questions for the UN to tackle are the Syrian civil war and resulting refugee crisis and about what can be done to prevention future conflicts and build peace.
