The best choice is "countries, such as the United States,"
Commas can be used before and after non-essential phrases. These parenthetical expressions can be set aside and not change the meaning of a sentence. The United States is listed as an example. If the country is set aside, it would not change the meaning of the sentence. Therefore, that phrase can be set off by commas.
