New details on the conflicts of interest.

On Thanksgiving Day, a Philippine developer named Jose E. B. Antonio hosted a company anniversary bash at one of Manila’s poshest hotels. He had much to be thankful for.

In October, he had quietly been named a special envoy to the United States by the Philippine president, Rodrigo Duterte. Mr. Antonio was nearly finished building a $150 million tower in Manila’s financial district — a 57-story symbol of affluence and capitalism, which bluntly promotes itself with the slogan “Live Above the Rest.” And now his partner on the project, Donald J. Trump, had just been elected president of the United States.

After the election, Mr. Antonio flew to New York for a private meeting at Trump Tower with the president-elect’s children, who have been involved in the Manila project from the beginning, as have Mr. Antonio’s children. The Trumps and Antonios have other ventures in the works, including Trump-branded resorts in the Philippines, Mr. Antonio’s son Robbie Antonio said.

Isn’t that just cozy. Antonio is a special envoy to the US, and Trump is the next president of the US. How pleasant for both of them and their children.

Mr. Antonio’s combination of jobs — he is a business partner with Mr. Trump, while also representing the Philippines in its relationship with the United States and the president-elect — is hardly inconsequential, given some of the weighty issues on the diplomatic table.

Among them, Mr. Duterte has urged “a separation” from the United Statesand has called for American troops to exit the country in two years’ time. His antidrug crusade has resulted in the summary killings of thousands of suspected criminals without trial, prompting criticism from the Obama administration.

Situations like these are already leading some former government officials from both parties to ask if America’s reaction to events around the world could potentially be shaded, if only slightly, by the Trump family’s financial ties with foreign players. They worry, too, that in some countries those connections could compromise American efforts to criticize the corrupt intermingling of state power with vast business enterprises controlled by the political elite.

“It is uncharted territory, really in the history of the republic, as we have never had a president with such an empire both in the United States and overseas,” said Michael J. Green, who served on the National Security Council in the administration of George W. Bush, and before that at the Defense Department.

Or such a corrupt, self-serving, defiant president. The combination is going to be lethal.

a review by The Times of these business dealings identified a menu of the kinds of complications that could create a running source of controversy for Mr. Trump, as well as tensions between his priorities as president and the needs and objectives of his companies.

In Brazil, for example, the beachfront Trump Hotel Rio de Janeiro — one of Mr. Trump’s many branding deals, in which he does not have an equity stake — is part of a broad investigation by a federal prosecutor who is examining whether illicit commissions and bribes resulted in apparent favoritism by two pension funds that invested in the project.

Several of Mr. Trump’s real estate ventures in India — where he has more projects underway than in any location outside North America — are being built through companies with family ties to India’s most important political party. This makes it more likely that Indian government officials will do special favors benefiting Mr. Trump’s projects, including pressuring state-owned banks to extend favorable loans.

There’s Turkey. Will Trump look the other way while Erdogan keeps arresting dissidents and academics in exchange for favors to Trump’s business interests there?

What is clear is that there has been very little division, in the weeks since the election, between Mr. Trump’s business interests and his transition effort, with the president-elect or his family greeting real estate partners from India and the Philippines in his office and Mr. Trump raising concerns about his golf course in Scotland with a prominent British politician. Mr. Trump’s daughter Ivanka, who is in charge of planning and development of the Trump Organization’s global network of hotels, has joined in conversations with at least three world leaders — of Turkey, Argentina and Japan — having access that could help her expand the brand worldwide.

What is that? Why was she even allowed to do that? Why is any of this being allowed?

Then there’s that hotel in Rio, and the investigation by a federal prosecutor into why two pension funds invested so heavily in the hotel when it’s not even finished and is a risky investment?

And a lot more.
