Sorry that I'm not going to spend the time to look them up, but there are extreme nationalistic military officers who take this position. What I'm saying is not controversial in foreign policy literature, though perhaps the position is more often strongly implied than literally stated. Also, realize that the Chinese government seems to have less control over the statements of its military officers; I can't imagine U.S. officers making statements like these.
Try searching for 'kill a chicken to scare the monkeys'. A popular meme (at least popular enough that I've encountered it many times) is that China suffered a "century of humiliation" at the West's hands, that China is ascending and the U.S. is in decline, and now China will take what it wants as the great power of the world, including control of their region and territory from their neighbors (some of whom have security guarantees from the U.S.).
As far as actions, for example the Chinese military actively have harassed U.S. and allied nations' ships and planes, including causing a few serious collisions.
