Having international submarine cable will enable Thailand to attract global content providers such as Google or Facebook to shift some of their server capacity to the country, instead of hosting their servers in Singapore as they do now.
Mr Teerarat said Thailand needs at least three new international submarine cable lines to accommodate surging internet traffic demand.
There are only 10 submarine cables in Thailand, compared with over 15 in Singapore and Malaysia, he said.
Also, submarine cables offer 30% lower investment and maintenance costs than terrestrial cables, said Mr Teerarat.
