Donald Trump has congratulated Turkish President Recep Tayyip Erdogan on his victory in Sunday's referendum that gave him sweeping new powers.
In a phone call, the US president also thanked Mr Erdogan for supporting America's missile strike on a Syrian government airbase on 7 April.
In the poll, 51.4% of Turkish voters backed the changes.
Mr Erdogan rejected criticism from international monitors who said he had been favoured by an "unequal campaign".
"Know your place," he told the observers.
The narrow victory was ruled valid by Turkey's electoral body, despite claims of irregularities by the opposition.
In a separate development, Turkey extended the state of emergency for three months. The measure, introduced after a failed coup last July, was set to expire in two days.
