Dr Wei Yang, who won a £500,000 contract to design plans for Hunan province, said the Buckinghamshire town was an "obvious influence".
The managing director of Wei Yang and Partners said her designs would draw on the town's mix of residential and green areas.
"Milton Keynes is the most successful new town in the world," Dr Yang said.
"[It] offers a strong and friendly community, which has stood the test of time."
She said the design of the town adhered to the Chinese principle of feng shui - "the harmony of the natural and human environment" - and would be incorporated into the design, funded by Chinese authorities.
London-based Wei Yang and Partners, founded in Milton Keynes in 2011, still has an office in the town because it is seen as a good example for those involved in town planning.
"I don't think your average Chinese person knows about Milton Keynes but it is certainly very well known in the planning field," said Dr Yang.
She said there were "a lot of very important design philosophies" behind the 46-year-old town's original plan.
"Chinese visitors are always impressed by the green setting, and see it as a model for building long-term vision and community," she said.
"If you think about Milton Keynes, the park system integrates the best of the residential areas and also the best of the natural environment.
"It makes the whole city accessible."
Chris Lowsley, from the government's UK Trade & Investment body, said China had to look carefully at how it planned its new cities because of the enormous growth of its urban population.
He said in his dealings with the cluster of Chinese businesses in the town he found it was the feng shui that was attractive to them.
"They like the energy there, they like the grid form and the way it is laid out," he said.
"The Chinese like both the environment of Milton Keynes and the friendliness of the people."
Dr Yang revealed one master plan had been finished and the company was in the process of creating "detailed design and guidance" that the Chinese government could put in place.
The "feng shui" of Milton Keynes has provided the inspiration for two new cities in China, planners have said.
