Work will start this year on a 400km railway line and a new seaport in Cambodia, with funding coming from Chinese sources.
Cambodia Iron and Steel Mining Industry Group (CISMIG) and China Railway Major Bridge Engineering have signed an agreement to jointly invest US$11.2 million in the projects.
CISMIG is 70 per cent Chinese-owned.
The railway line will cost $9.6 billion to build and will run from Preah Vihear province through Kampong Thom and Kampong Speu to Koh Kong.
Construction of the seaport in Koh Kong will cost $1.6 billion.
It will support the metal and mining industries in Preah Vihear, providing an outlet for exports to China and other markets.
Work on both projects will begin in July and is due to be completed in November 2017.
