Donald Trump owns a sprawling international empire of scores of business interests, many of them in other countries. Other presidents have placed their assets in a blind trust to remove any conflict of interest. Trump has refused to do so. He says his adult children will manage the business but he can’t be unaware that his decisions as president will affect the success of his empire.

During the campaign, Trump broke tradition by refusing to release his tax returns. Now it appears there is no likelihood that he will seaparate himself from his far-flung business interests.

Turkey is a nation in crisis, scarred by government crackdowns following a failed coup attempt and on a potential collision course with the West. It is also home to a valuable revenue stream for the president-elect’s business empire: Trump Towers Istanbul.

Donald Trump’s company has been paid up to $10 million by the tower’s developers since 2014 to affix the Trump name atop the luxury complex, whose owner, one of Turkey’s biggest oil and media conglomerates, has become an influential megaphone for the country’s increasingly repressive regime.

That, ethics advisers said, forces the Trump complex into an unprecedented nexus: as both a potential channel for dealmakers seeking to curry favor with the Trump White House and a potential target for attacks or security risks overseas.

The president-elect’s Turkey deal marks a harrowing vulnerability that even Trump has deemed “a little conflict of interest”: a private moneymaker that could open him to foreign influence and tilt his decision-making as America’s executive in chief.

But the ethics experts eyeing Trump’s empire are now warning of many others, found among a vast assortment of foreign business interests never before seen in past presidencies. At least 111 Trump companies have done business in 18 countries and territories across South America, Asia and the Middle East, a Washington Post analysis of Trump financial filings shows….

Some companies reflect long-established deals while others were launched as recently as Trump’s campaign, including eight that appear tied to a potential hotel project in Saudi Arabia, the oil-rich Arab kingdom that Trump has said he “would want to protect.”

Trump has refused calls to sell or give his business interests to an independent manager or “blind trust,” a long-held presidential tradition designed to combat conflicts of interest. Now, policy and ethics experts are scrambling to assess the potential dangers of public rule by a leader with a vast web of private business deals.

“There are so many diplomatic, political, even national security risks in having the president own a whole bunch of properties all over the world,” said Richard Painter, chief White House ethics lawyer under President George W. Bush.

“If we’ve got to talk to a foreign government about their behavior, or negotiate a treaty, or some country asks us to send our troops in to defend someone else, we’ve got to make a decision. And the question becomes: Are we going in out of our national interest or because there’s a Trump casino around?” Painter added.
