The National Security Council (NSC) has played down concerns that the United States used its Bangkok embassy for phone-tapping and other types of surveillance.
NSC secretary-general Paradorn Pattanatabut said Friday he did not believe the US would use Thailand as a spying base. Information which flows through embassies in Thailand is not likely to be deemed crucial content by the US, he said.
However, Lt Gen Paradorn said he will remind the US that any such spying would be a rights violation and a crime under Thai law.
Government spokesman Teerat Ratanasevi said there have been no intelligence reports about such violations by the US in Thailand.
Scattered media outlets have reported claims that the US has been using many of its embassies, including those in Indonesia and Thailand, as monitoring stations, including for alleged phone-tapping.
Indonesia summoned the Australian ambassador in Jakarta Friday over a "totally unacceptable" report that his embassy was among diplomatic posts in Asia being used in a vast American surveillance operation.
China and Malaysia have demanded an explanation from Washington over claims that American embassies and consulates in the region were being used for monitoring phone calls and communications networks.
The Sydney Morning Herald newspaper, amplifying an earlier report by the German magazine Der Spiegel, said earlier this week that a top-secret map leaked by fugitive intelligence analyst Edward Snowden showed 90 US surveillance facilities at diplomatic missions worldwide.
