From 2013 to 2017, China has invested about US$1 billion annually in Cambodia, making it the largest foreign direct investor. A significant share of that investment has been directed to Sihanoukville province. Chinese investments there are concentrated in a few key sectors such as casinos, real estate, resorts, and a deep-water port. Casinos are being built at such a fast pace that there is no agreement on how many there are: estimates range from 30 to 150.
