The Trump Organization has agreed to a new Middle East golf course and real estate deal that involves a Qatari government-owned firm, two weeks before President Trump is set to travel to Saudi Arabia, Qatar and the United Arab Emirates on a state visit.

The project in Qatar, a key U.S. ally and home to a major American military base, is a partnership with Qatari Diar, a real estate company established by the country’s sovereign wealth fund and chaired by a government minister.

Eric Trump, the president’s son who runs the family business, traveled to the Middle East this week to attend a cryptocurrency conference and promote the company’s real estate developments, which include a separate Trump-branded tower in Dubai, the largest city in the Emirates.

The two projects will also involve Dar Global, the international subsidiary of the private Saudi real estate firm Dar Al Arkan, which is leading the project and has close ties to the Saudi government. The Qatar project was initially reported by Reuters.

The Trump golf course in Qatar is the most recent in a series of projects that directly involve foreign governments. And it is just one of a growing list of ways that the Trump family is profiting from Mr. Trump’s refreshed status after his return to the White House, including two cryptocurrency ventures.

In Oman, the Trump family has partnered on a Dar Global hotel and golf project that is being built on state-owned land, and the government will get a share of the revenues generated, according to company documents. In Serbia, the Trump family is planning a new hotel in collaboration with Jared Kushner, Mr. Trump’s son-in-law.
