@oristarA,
In China, politics
of the ruling class controls media, while in United States, media is independent of politics.
Key words: relationship, media, politics, U.S., China
I removed the first parenthesis. On the second parenthetical phrase, I removed parenthesis and their contents. I like it better that way, though I see why your are trying to be consistant in the comparison.
I don't endorse the accuracy of the statements, of course.
