There is large investment potential in the telecommunications sector, especially given rapid technological change and continual need to upgrade the system. As telecommunications technology converges with other media, investment is needed in new technology, such as 3G and broadband. In addition to investments in new technology and network coverage, there will be a recurring need to invest in maintenance of the system. The two state-owned enterprises, TOT and CAT, are likely to continue to play major roles in new investment, especially in the form of joint-ventures. With liberalization of the market, foreign players will become more present. To facilitate new investment and telecommunications sector development, regulatory issues have to be clarified to increase business certainty.
