Cambodia had approved domestic and foreign investment projects worth 4.9 billion U.S. dollars in 2013, up 69 percent from 2.9 billion U.S. dollars a year earlier, Prime Minister Hun Sen said Monday. Investments have been made in various sectors such as garment and shoe manufacturing, banking and finance, telecommunications, agriculture processing, electronic equipment and supplies manufacturing, tourism resort development, and real estate, the premier said during the 4th Cambodia-Vietnam Conference on Investment Promotion. Foreign investors in the country are mostly from China, South Korea, Vietnam, Malaysia, and Japan. Hun Sen said more inflow of foreign investment in Cambodia has clearly showed the confidence of investors in the country's political stability and potential for business opportunities. Sok Chenda Sophea, secretary general of the Council for the Development of Cambodia, which is responsible for attracting investors to the country, foresaw that new investors would continue coming to Cambodia due to the country's political stability, good business environment and preferential laws and regulations.
