From the PLA version of events:

This video released by the Chinese PLA Southern Theater Command shows that the US RC-135 aircraft abruptly changed its flight attitude and performed dangerous approaching maneuver at 11:25:17 a.m.

What an utter crock of shit. PLA aircraft is the only one who changed their course in both videos. How contradictory they can be, even their own video shows no change from the US aircraft. Idiots.
