The article points out some reasons for the U.S. to dislike China, and just mentions China feeling the same, but it doesn't display reasons for that. At least, you can jump into the other article to try to understand what's happening in the other side.

The piece doesn't elaborate on the reasons for said dislike, but it does quantify what I think many assumed was bubbling under the surface in both countries.
