US and Britain pledged Monday to give $27 million over five years for health issues and HIV-AIDS response.
In a signing ceremony Monday night, representatives of the two governments said projects devoted to education on AIDS, the virus that causes it, reproduction, sexual health and children's lives in Cambodia.
The money comes ahead of meetings Tuesday and Wednesday that will determine additional aid from donor countries.
USAID Director Erin Soto said the US aid agency provides Cambodia with about $20 million a year in HIV-AIDS funding, and in the subsequent years, USAID will focus on protection, treatment, and care for those with the disease.
Elisabeth Smith, a representative of Britain's Department for International Development, said projects would focus on preventing HIV transmission, especially among high-risk groups.
