The volatility of price is one of the major risks of crude oil imports. This paper presents an expended Price-Risk model, in which price is involved to determine the optimal crude oil import structure. We use the dataset of crude imports between September 2015 and August 2016 for the simulation. The results imply that the Middle East is still the most significant area to ensure the oil supply security. Imports from stable countries can effectively diversify the oil supply risks. In the long run, it is benefit to import oil from diversified countries, such as UAE, USA, Norway, Australia, Azerbaijan, Kazakhstan, Egypt, Qatar, and Nigeria.
