The United Nation is hosting a special summit on Sudan this Friday, which will discuss the planned referendum vote in South the country.
Barak Obama, the US president, will be among the leaders attending the meeting in New York.
The referendum will determine whether the south should be independent from the north.
With four months left to January's vote, however, the UN says preparations are 'hopelessly' behind schedule. Voter registration is only expected to start next month.
