The White House said on Monday that actions by China in the Taiwan Strait and South China Sea reflect a "growing aggressiveness" by Beijing's military that raises the risk of an error where someone gets hurt.
The U.S. Navy on Sunday released a video of what it called an "unsafe interaction" in the Taiwan Strait, in which a Chinese warship crossed in front of a U.S. destroyer.
"It won't be long before somebody gets hurt," White House spokesperson John Kirby told reporters, referring to what he called "unsafe" and "unprofessional" intercepts by China. "It wouldn't take much for an error in judgment or a mistake to get made."
