As US President-elect Donald Trump continues to develop his business empire, there is growing concern about how can he separate business and politics.

From tower blocks to golf courses, Donald Trump has built a global business empire like no other U.S. president.A portfolio of companies spanning the globe that are now fueling concerns about how President Trump can separate business and politics.

Just two weeks before the election Donald Trump opened his latest luxury hotel a few minutes walk from the White House here in downtown Washington. He won a contract from the U.S. government to lease the Old Post Office and Clock Tower for the next 60 years, And for some, that now makes him both landlord and tenant.

He's not the first president to face this dilemma. But where even Republican predecessors such as George W Bush and Ronald Reagan sold off their business interests to avoid conflicts of interest, Trump will hand over his to his children...though he doesn't appear to be clear on the definition.

"I don't know if it's a blind trust if Ivanka, Don and Eric run it … I don't know - is that a blind trust " Donald Trump said.

His organisation told CCTV this management transfer to three of his children would comply with all rules and regulations.Democracy campaigners disagree.

"If we saw this kind of arrangement discussed in other countries, particularly in Africa or other parts of the world where you're going to see a president and his family running the business, we would consider that one of the features of a banana republic. "said Meredith Mcgehee, Campaign Legal Center Strategic Adviser.

There's no legal obligation for Trump to put his businesses into blind trusts. But critics say it's crucial for Trump's overseas interests. Four years ago, the President-elect opened new property in Turkey -- one of the most geopolitically sensitive places in the world.
 
Meredith Mcgehee said "Making foreign policy is something that is solely within the power of the President, so he has a wide ranging portfolio. And if there is going to be a discussion made about something that is affecting a foreign country that is where the conflict potentially arises."

As the ethical discussion continues, Trump continues to develop his business empire a new hotel brand launched shortly before the election.
