Thousands of observers were in Sudan to watch the vote and only a few isolated reports of intimidation or violence have come out. The European Union had 110 observers in Sudan and visited 800 centers during voting. De Keyser added that their work in Sudan is not done, despite the successful voting process.

"It is important, I would say even crucial, to remember that this is not the end of the process," De Keyser explained. "The crucially important results-processing phase will continue for the next two-to-three weeks."

The African Union and Carter Center released their results on Sunday and Monday. They said the same thing as the European Union, the vote was free, peaceful, fair and transparent.

Now all the results are being counted at the county level and preliminary results from the counties are expected later this week. Final results will be announced in mid-February, according to the referendum commission’s schedule.

Most likely, the north and south will then go back to the negotiating table and figure out how to make their divorce as smooth as possible.
