Kenya is negotiating a new loan of about $4 billion from China to help in building the Naivasha-Kisumu-Malaba standard gauge railway.
Treasury Secretary, Henry Rotich, is expected to fly to China in the coming weeks to perfect the papers.
The $4 billion debt from the Asian giant amounts to nearly six per cent of gross domestic product of Kenya.
The on-going 495-kilometre Mombasa-Nairobi standard gauge rail line, set to open on June 1, is being financed with a $2 billion commercial loan from the Chinese government.
Kenya and Uganda last month agreed to jointly implement the Nairobi-Malaba-Kampala rail project.
