Welcome to “Hometown America,” as Jackson Hole is called in Chinese, a mammoth real-estate venture that is an exacting pastiche of an American frontier town, albeit one with a wine-tasting pavilion, a spa and security guards dressed as park rangers, who salute every passing car.

Modest entry-level homes sell for $625,000. Larger abodes — described by Jackson Hole’s developers as castles — have an attached vineyard and fetch nearly $8 million. The developer, Ju Yi International, says that more than 90 percent of the 1,500 homes have already been sold. Occupying more than a square mile of arid land in northeast Hebei Province, Jackson Hole has plenty of room to expand.

After weekend services at the nondenominational church, many residents gather at the nearby clubhouse, adorned with Navajo art and wagon-wheel chandeliers, for the all-you-can-eat buffet featuring “American pork chops,” smoked salmon and, in a nod to local tastes, tree ear fungus.

On a recent Sunday, the attire could be best described as American casual: flannel shirts, sweatpants and sneakers. The tables were packed with extended families, nearly all of whom were drinking imported red wine.
