National Telecom (NT) of Thailand has submitted a THB16.1 billion (US$480 million) proposal to the Finance Ministry for building four new international submarine cables connecting Thailand to Singapore, Japan, and Europe. The project aims to replace ageing infrastructure and increase bandwidth to support rising data traffic driven by artificial intelligence, cloud computing, and hyperscale data centres. The budget allocates THB6.6 billion for two systems to Singapore, THB4 billion for a system to Europe, and THB5.5 billion for a system to Japan. The proposal is still in the preparatory stage, requiring partner selection, site surveys, and multiple government and environmental approvals before work can commence. NT argues that the new cables are for enhancing Thailand's competitiveness and supporting digital innovation in various sectors. The project is planned for the 2027 fiscal year and is linked to a broader emergency decree aimed at addressing the energy crisis.
