NEW DELHI — Donald Trump Jr., who has spent the week in India pitching new luxury high-rises that bear his family’s name, took the stage before a crowd of about 200 on Thursday. “Building a Better Mumbai,” the banner behind him proclaimed.

“We’re actually delivering true luxury,” Mr. Trump told the guests, who were greeted by a red carpet, lit candles and a jazz band. “We’re actually delivering buildings in the Indian marketplace that you can take out of that marketplace, put in any cosmopolitan of the world and say, ‘This is on par with some of the best.’”

The Trump Organization is reaping the windfall from India’s admiration for President Trump. He may have low approval ratings at home, but he appears well liked in a country with one of the fastest-growing populations of millionaires in the world.

The Trump brand “spells glamour more than luxury,” said Kalyani Chawla, a brand consultant and former executive at Christian Dior in India who attended the event. “I think it’s all about Donald Trump, honestly,” she said, “any idea of Donald Trump in general, regardless of the fact that even he’s surprised he’s the president of the United States.”
