Rwanda was elected as one of the five non-permanent members to the Security Council for a two-year mandate that commences on 1 January 2013.
Though unopposed for one seat for the African group, garnered 148 votes out of a possible 193 votes, more than the required two thirds of the required vote from the countries present.
Rwanda now replaces South Africa whose mandate ends on December 31, 2012.
The confidence shown by the 148 voters will not go down well in Kinishasa after a DR Congo Delegate objected to Rwanda's bid by saying, "My delegation rejects Rwanda being part of the Council."
Her point of order was however dismissed by the General Assembly President Vuk Jeremic saying no representative shall interrupt the voting process whatsoever on any grounds.
DR Congo went on to vote itself and got just the one vote possibly in protest.
Foreign Affairs minister Louise Mushikiwabo took to her Twitter account to say, "It's the right thing, a testament to how far we've come and our commitment to international peace."
The five permanent Council members, which each wield the power of veto, are China, France, Russia, the United Kingdom and the United States. Other non-permanent members Azerbaijan, Guatemala, Morocco, Pakistan and Togo will remain on the Council until the end of 2013.
