Thailand
Thailand sits at a crossroads of Indo-Pacific submarine connectivity, served by a mix of active regional and long-haul cables spanning the Indian Ocean, South China Sea, and beyond — though its landing-point infrastructure remains under active documentation.

Submarine cable connectivity
Thailand occupies a geographically significant position in South-eastern Asia, flanked by the Gulf of Thailand to the south-east and the Andaman Sea to the south-west. That dual coastal exposure, facing both the Pacific-oriented cable corridors of the South China Sea and the Indian Ocean routes running toward the Middle East, Europe, and East Africa, gives the country meaningful options for diverse submarine cable landings.
Six cables are recorded as serving Thailand. The most significant long-haul system is Asia-Africa-Europe 1 (AAE-1), which entered service in 2017 and spans one of the most strategically important routes in global telecommunications — linking South-east Asia through the Indian Ocean to the Persian Gulf, East Africa, and Europe. Its presence in Thailand's cable mix provides a direct path to some of the world's busiest traffic corridors without routing through Singapore or other regional hubs.
The Asia America Gateway, at roughly 20,000 kilometres, extends Thailand's reach across the Pacific toward the United States, complementing the westward capacity offered by AAE-1. Together, these two systems represent connectivity in opposite directions from the Thai coast — a foundation for genuine route diversity that reduces dependence on any single cable corridor.
The remaining active cables — MT, SJC, and TIS — add further regional depth. SJC is a well-established system threading through South-east and North-east Asia, while the others contribute intra-regional capacity. The retired ASEAN cable, for which operational dates are not recorded, reflects the longer history of submarine investment in the country and the normal cycle of infrastructure replacement as demand grows and older systems reach end of life.
Capacity and resilience
With five active cables spanning both Pacific and Indian Ocean directions, Thailand's international connectivity is more diversified than many of its regional neighbours. The presence of systems oriented toward multiple ocean basins limits the risk of a single cut or fault isolating the country's international traffic. That said, the true depth of resilience depends on the geographic spread of landing points — whether cables come ashore at separate facilities along different stretches of coastline, or converge on a single landing station.
Landing-point documentation
No landing points for Thailand are documented in this register at present. Work to compile and verify that data is ongoing. The cable list above reflects confirmed service to the country; the precise locations where those systems make landfall will be added as documentation is completed.
