US President Donald Trump's daughter Ivanka has amazed her father's conservative supporters by suggesting that the refugee crisis is a global issue that wouldn't be fixed just by opening up borders.

Ms Trump, who serves as an unpaid adviser to the President in the White House, has been in Berlin, Germany for the W20 summit alongside German Chancellor Angela Merkel, a proven advocate of opening up borders for refugees.

In an interview with NBC reporter Hallie Jackson, she called the huge swathes of refugees fleeing their home countries in the Middle East and Africa a "global humanitarian crisis". She also said it was an issue that "we have to come together and we have to solve".

When quizzed on whether part of the solution to the crisis was "opening the border to Syrian refugees in the US", Ms Trump said that was a good starting point.

"That has to be part of the discussion, but that's not going to be enough in and of itself," she said. "I'm incredibly hopeful that legislation is put together."

The comments mark a huge departure from the policies of her father - not least of all his two failed executive orders on immigration that looked to suspend the country's refugee programme and ban people from six Muslim-majority nations, including Syria, from entering the US.

Ms Trump's remarks have astounded and angered many of President Trump's supporters, including high-profile conservative Milo Yiannopoulos, who posted an article featuring her comments alongside a caption that read "WHAT R U DOING IVANKA".

Another prominent conservative, Infowars editor Paul Joseph Watson, called Ms Trump "a globalist", saying she is "at best incredibly misinformed and naïve" and should not be advising her father.

Even neutral news organisations like Politico have called Ms Trump's comments "a direct aversion" to the President's policies - with others suggesting her newly expressed views may be a result of the time spent with Germany's Ms Merkel.
