President Donald Trump's sweeping ban on people seeking refuge in the United States is no solution to problems, Turkish Prime Minister Binali Yildirim says, adding that Western countries should do more to help ease Turkey's refugee burden.
The new Republican president on Friday put a four-month hold on allowing refugees into the United States and temporarily barred travellers from Syria and six other Muslim-majority countries, although NATO ally Turkey was not among them.
When asked by a reporter on Saturday about Trump's ban during a joint news conference with British Prime Minister Theresa May in Ankara, Yildirim said: "Regional issues cannot be solved by closing the doors on people. We expect the Western world to lighten Turkey's burden."
"You can build a wall but it's not a solution. That wall will come down like the Berlin wall," he said, adding Turkey has spent some $US26 billion ($A34 billion) on sheltering refugees.
May, who met with Trump in Washington a day earlier, told the news conference that the United States was responsible for its position on refugees.
She has previously said a "special relationship" between the United States and Britain meant the two countries could speak frankly to each other when they disagreed on issues.
Yildirim said little directly about Trump.
"We are not very informed about Trump's decisions. But problems are solved through dealing with the causes," he said.
Turkey, a member of the US-led coalition against Islamic State, has been hoping for a reset in its relationship with the Washington under the Trump administration.
Ankara was long frustrated by former President Barack Obama's decision to back a Syrian Kurdish militia. Turkey considers the group a terrorist organisation.
Turkey is home to the world's largest refugee population sheltering some 3 million people, most of them Syrians.
