These are the four consortium members already mentioned in announcements to date.

1. Shenzhen Yandina Port Holdings Co Ltd
2. China Railway Construction Corporation International Co Ltd.
3. Hong Kong Baofeng International Co Ltd.
4. Shanghai Tsingshan Mineral Co Ltd.

I’m attempting to identify the fifth Chinese state owned company.

“China Harbour Engineering Co., locally known as CHEC. In Cameroon, CHEC has the country’s largest projects: the first and second stages of the Kribi complex will cost $1.3 billion, while it’s also building a $453 million highway linked to the port, holds a contract to dredge the port of Douala and has signed an accord for a railway to the Mbalam iron-ore deposit.” from an article 2 years back.
