CAMBODIA Television Network will start construction next month on concrete bunkers for troops stationed near the Thai border as part of a controversial programme in which businesses provide support to military units. Tok Kimsay, director of CTN’s charitable foundation, said CTN had collected US$20,876 in donations as well as 27 tonnes of cement for the project. The bunkers are intended to cover a 113-kilometre stretch of border primarily in Oddar Meanchey province and will replace the dugout bunkers currently in use. CTN was one of the companies named in a document signed in February by Prime Minister Hun Sen that set up funding arrangements between businesses and military units, a move rights groups said could obscure military funding and leave troops beholden to private interests.
