Of course, but one should also realize that much of the time U-turns don't happen. The fact that U-turns occurred, can occur and will occur in the future does not mean that China will, in this particular instance, do a U-turn on North Korea. Nor does it demonstrate your assertion that influence can bring such a U-turn about.
