The agreement in the east was negotiated in Asmara under the auspices of the Eritrean government. There were very few international partners directly involved in its negotiation.
From what we can see, though, it looks like a very good comprehensive agreement that we will look to support. As to the willingness of the signatories to move forward beyond the agreement, the proof will be in the pudding, but as a text it looks like something we can support. Internationally, all of us are looking at ways we can support its implementation.
In terms of the refugee, I have read the media reports and I think what has been suggested is that the ICC, which is investigating war crimes in Darfur, should interview this man. The issue of the Janjaweed as proxy for the Government of Sudan has been around for a very long time; there have been lots of allegations that, yes, there is a direct link.
