The developer whose name prominently adorns buildings all over New York, and increasingly across America, is branching out – to Dubai.

Yesterday, Donald Trump announced his firm had entered an exclusive joint venture with Dubai-based Nakheel, a government-owned company and one of the biggest developers on the island. Their first joint project will be a gold-colored, 50-story, lotus shaped hotel tower on one of the so-called Palm Islands. The three manmade islands are being built to resemble palm trees, off Dubai’s shore in the Persian Gulf. The partnership between Mr. Trump and Nakheel will include direct investment, sales, marketing, management, and, of course, branding.

“The partnership with Nakheel represents an unprecedented mega-opportunity for us with the increasing popularity of the Trump brand on a global basis,” Mr. Trump said in a statement.

The Palm Trump International Hotel & Tower will sit on the main trunk of one of the islands, called Jumeirah. Plans for the three islands include space for more than 5,000 inhabitants in 2,400 private residences, 50 hotels, and a variety of entertainment attractions.

Dubai, one of the seven emirates that make up the federation of the United Arab Emirates, has become the Arab world’s hub of business and tourism in recent years. It boasts double-digit annual GDP growth and has a booming luxury tourism industry. In one sense, Mr. Trump and Dubai are a good match: Both have tried to brand themselves by developing ambitious and flamboyant properties.

For years, Mr. Trump has aimed to build the tallest residential buildings in New York, and he now owns that title in the 90-story Trump World Tower near the United Nations. Mr. Trump is currently developing the largest residential building in North America in Chicago, and recently announced the groundbreaking of the tallest building in New Jersey.

Dubai is racing to build the world’s two tallest towers. The tallest hotel in the world is in Dubai, the Burj Al Arab. It claims to be the world’s highest-rated hotel and includes leopard-skin furniture, fire-spouting volcanoes, and suites that cost as much as $15,000 a night.

Additional monumental reclamation projects are planned as Dubai extends into the Gulf. Another Nakheel coastal development, the World, will arrange 300 man-made islands in the shape of the seven continents. Mr. Trump is also planning a development there.

The chairman of Nakheel, Sultan Ahmed Bin Sulayem, is also a top government aide.

He said in a statement, “The Trump signature brand is synonymous with the most prestigious properties in the world, and we embrace his interest in working together.”

Donald Trump Jr., a vice president for the Trump Organization, helped negotiate the deal along with his sister, Ivanka. He told The New York Sun that he hopes the Trump project in Dubai will have a “big influence in bringing Americans over there.”

“The development they are doing over there is incredible,” he added. “They have, in an area smaller than Rhode Island, 10% of the world’s construction cranes. We want to be a part of it.”

After his recent tour of Dubai, the younger Mr. Trump said he was surprised with the level of Westernization and the pace of development. “Dubai has done an incredible job of making themselves a much more secular nation,” he said. “There were times I didn’t realize I wasn’t downtown … They are building these islands in the middle of nowhere. Flying over them by helicopter, you really realize their size and scope.”

Mr. Trump said the Dubai deal was part of a larger push by the Trump Organization to become less “New Yorkcentric.”

If the fill materials used to construct one Palm island were placed end to end, a wall measuring more than 6-feet high would encircle the globe three times, a Nakheel Web site said.
