China may diversify foreign investment

China is the biggest investor in South Sudan's oil industry.

Fighting between rival army factions in the country has disrupted its oil output.

Sijin Cheng, a commodities analyst at Barclays, told the BBC's Rico Hizon that the trouble in South Sudan had significant implications for the oil market and China's oil imports.

She said that Beijing was likely to "diversify" its foreign investments into more stable countries.
