The US Department of Agriculture named Wakanda the country with which it entered into a free trade deal, despite being a fictional kingdom from the comics and Black Panther movie.

A spokesman for the ministry said the name of the fictional country was added to the list for testing purposes, Time reported.

In Marvel movie, Wakanda is the East African homeland of the Black Panther superhero.

The country was removed from the list shortly after the American media asked question over this. After that, jokes appeared in the networks that states started a trade war.
