The government is intensifying efforts to restore international confidence in Thailand after Friday's earthquake, Prime Minister Paetongtarn Shinawatra said.

Speaking at the Thailand Investment and Expat Services Center (TIESC) opening ceremony at One Bangkok, Ms Paetongtarn on Monday addressed the international community regarding the collapse of the new State Audit Office (SAO) building during the earthquake.

She said the collapse was due to technical errors affecting that particular building while reassuring that no other buildings in Bangkok were at risk of collapsing as they adhered to earthquake-resistant standards.
