Answer: Serbia.
Explanation:
This is about a concert that Amy did in Belgrade (capital of Serbia), where the Serbian minister of defense said that the concert was "shame and a disappointment" and the host of the show said "Well, so is your country"
This caused a big controversy, then the Serbian Ambassador wrote to the host that he was disrespectful.
Then, the country that called for an boycot to the show of E! was Serbia.
