What term describes a story set within a foreign culture, but described by
an outsider?

Many stories and films contain elements of foreign cultures, or are
supposedly set in foreign lands, yet were written by outsiders of those
cultures, e.g.:
Tikki Tikki Tembo was set in ancient China, but was written by an American
author.
Sagwa, the Chinese Siamese Cat was set in ancient China, yet was made by
Canadians.
Avatar: The Last Airbender, contained many subtitle references to Chinese
and Japanese cultures, but was made in the United States.
Is there any term which could be used to collectively describe such works
or to describe the resulting "culture not-quite-matching-the-real-thing"?
