The name of an imaginary country in the 2018 movie Black Panther appeared this week in an online list of U.S. trading partners. The fictional country, called Wakanda, was listed among a group of nations that have trade agreements with the United States. The list was a creation of the U.S. Department of Agriculture, or USDA. The USDA told NBC News in a statement that it had used Wakanda during recent testing of the agency’s online publishing system. A USDA spokesman said “the Wakanda information should have been removed after testing and has now been taken down.” Wakanda is the name of a made-up African nation in the Marvel Comics superhero film Black Panther. The country is home of the Black Panther himself, Prince T’Challa. In the film, Wakanda is a developed, highly technological country.
