Film title character from the “glorious nation of Kazakhstan”

BORAT

This mockumentary character famously travels across America while wearing a bright green "mankini" and asking awkward questions. His catchphrase involves a very enthusiastic "Very nice!"

This clue refers to the mockumentary Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan, where Sacha Baron Cohen plays the bumbling, fictional Kazakh journalist Borat Sagdiyev. The phrase "glorious nation of Kazakhstan" is a direct quote from the film’s full title, making it a clear hint. The answer is simply the character’s name, Borat, which is both the title and the protagonist’s identity.
