Thailand, located in Southeast Asia, is a country with diverse topography ranging from mountains in the north to a large central plain and coastal regions. This geographical diversity impacts the distribution of its population of approximately 71 million, with dense urbanisation in Bangkok and other major cities, and sparse habitation in rural regions. Thailand's telecommunications sector is advanced with widespread internet and mobile phone coverage, even in remote areas, due to the government's Universal Service and "Thailand 4.0" initiatives aimed at digitalisation. There is a growing emphasis on renewable energy with solar, wind and bioenergy being actively explored, but the majority of power generation still comes from fossil fuels. The technology sector is a major government focus, with the country launching its Eastern Economic Corridor (EEC) digital free trade hub.
