The government is not trying to control access to information like communist countries," Mr Uttama said.
Wanchai Vach-shewadumrong, deputy managing director of Internet Thailand, a leading internet service provider, said the government should not implement the single gateway policy as it would not be practical and transparent.
"It will lead to strict control of the country's internet traffic similar to what the Chinese government is doing," he said.
Instead, he said policymakers could order all international internet gateway providers to cooperate to filter or block any content or any internet traffic that will pose a threat to national security. If service providers do not cooperate, the government can revoke their licences.
