18. september 2004 vedtog FNs sikkerhedsråd resolution 1564, som skulle presse den sudanske regering til at handle hurtigt for at forbedre situationen ved at true med muligheden for oliesanktioner, hvis resolution 1556 ikke efterleves eller hvis regeringen skulle nægte at acceptere en udvidelse af den fredsbevarende AU-styrke..
