Worth a total of almost $5.5 billion, the China Railway Construction Corporation (CRCC) has signed two railway construction deals in Africa. CRCC is tasked with building a $3.5 billion intercity railway line in Nigeria’s southwestern Ogun State and a $1.93 billion residential construction project in Zimbabwe.
