A subsidiary of China Railway Construction Corp Ltd has signed two projects in Africa with a total contract value of 9.1 billion yuan [$1.45 billion], the company said in a statement to the Shanghai Stock Exchange.
The value of the projects, located in Nigeria and Djibouti, equates to just under 2 per cent of China Railway's 2010 operating income, the company said.
China Railway has actively pursued overseas investments this year.
In late November, a consortium involving China Railway and Aluminum Corporation of China (Chinalco) announced a deal to develop an iron ore mine in Guinea.
The company is also part of a consortium of Chinese firms in talks with the Ecuadorian government on a gold mining project
