China is to build an $8bn oil refinery¹ in Nigeria.

中国将在尼日利亚投资建设一座80亿美元的炼油厂。

It will be the first of three refineries² under a deal signed in May between Nigeria's state oil company, NNPC, and the China State Construction Engineering Corporation (CSCEC).

The refinery（精炼厂，冶炼厂） will be built in the Lekki free trade zone of Lagos, Nigeria's biggest city.

The Chinese will cover 80% of the cost, and NNPC 20%, while the state of Lagos will provide land and infrastructure³.

Under the $23bn framework agreement signed in May, NNPC and CSEC will also build two other refineries, in Bayelsa and Kogi, as well as a fuel complex（复合体，综合设施） .

Nigeria already has four refineries, but they are widely seen to be poorly maintained（维护，维修） and only running at 40% of capacity.

As a result, the African country must currently import refined fuel, even though it is a major crude oil（原油） producer and exporter.
