At the moment, a lot of the negotiations are about what will happen after the referendum. These negotiations involve both the AU panel and the special envoy. We understand that some of these discussions include issues such as the state of the north in case the south wishes to secede.
So it's not only about what will happen in the south, which has up until now been a major issue. Currently, there's a focus on the relationship between the north and the international community, as well as on future diplomatic relations if sanctions are imposed in the event of secession.
It's an important issue for all sides. I believe it has become more prominent in the last few months, largely because of interventions on the part of the mediators.
