While most foreign investment in hydropower, oil and gas projects in these areas goes through formal channels as these sectors are controlled by the state and entail massive investment, the remaining foreign investment is largely informal. Given this lack of data and the reluctance of businesses to disclose information, the extent of such informal investment is difficult to ascertain but may be particularly high. In fact, large investment, much of it foreign direct investment (FDI), seems to have targeted not only mining and hydropower but also logging and most recently rubber, maize, paddy, sugarcane, jatropha and palm oil in resource-rich ethnic states, such as Kachin and Shan states.
