But all recent attempts have broken down. South Sudan shut down all oil production in January after accusing the north of stealing oil going through northern pipelines, and charging exorbitant fees. But South Sudan's Deputy Minister of Information Atem Yak Atem says that wonât stop his government from reaching out to its northern neighbor. "It is in the interest of our two peoples to be good neighbors. To cooperate, and weâve gone almost to the point of begging them. It is not out of weakness, but it is simply because we need stability within our country, and with our neighbors," he said. Until diplomats get talks back on track, soldiers like Alirdo will stay put, waiting for their orders to either fall back, or move forward.
That is one way to bargain with Moslems, cut off their oil and mass troops on the border. Sudan was expecting 50% of the oil revenue just for pipelining it out of South Sudan. Being unreasonable seems to be an inherent part of Islam.
Other than Sudan having already called for Jihad, I don't think South Sudan is concerned much about remaining neighbors with Islam. I think it's more about oil. It's been reported that China gets nearly 4.5% of its oil from South Sudan oil which used to be pumped through (North) Sudan's pipeline. South Sudan has reached out to China for emergency loans and assistance building the Kenya pipeline, but Chinese premier Hu Jintao has refused to offer support in construction, though China has offered bank loans and emergency aid to South Sudan. China finds itself in a tricky position: it is the biggest investor in oil in both Sudan and South Sudan. http://www.guardian.co.uk/commentisfree/2012/may/17/south-sudan-oil-pipeline
