South Sudan’s independence from the rest of Sudan is the result of the January 2011 referendum held under the terms of the 2005 Comprehensive Peace Agreement (CPA) that ended the decades-long civil war between the North and the South.
Among those expected to speak at the meeting, which will be followed by a flag-raising ceremony, is Secretary-General Ban Ki-moon, Assembly President Joseph Deiss and Vice President of South Sudan Riek Machar.
