The casino has been under strong criticisms mainly from the churches and other pressure groups for many months since Parliament amended the law to allow the establishment of casinos in the country.
Mr Tuilaepa said the government knew that tourism had been an economic booster for the country and having such a place like the casino was another avenue for economic development.
He said he was aware of the concerns raised by church leaders and several non-governmental organisations about casino operations in the country. But he said as a leader he had to think of ways to sustain and develop the country.
