China imports 4.5% of its oil from S. Sudan

Nonetheless, there is reason for optimism concerning the relationship between South Sudan and China. Chinese foreign policy is based on principles of non-interference, mutual interest and mutual benefits, and China has no special interest in Sudan except for their national strategic interest. South Sudan is in far better position to ensure that strategic interest, given the fact that most oil and agricultural potential is in the South. In fact, of the 5 percent of China’s oil needs that are met by exports from Sudan and South Sudan, the crude oil export of South Sudan alone meets about 4.5 percent of it.
