Haven’t heard that one, but here’s an example, on the left is BBC’s Chinese version, on the left is the English version:

Christ, this has to be a deliberate effort to present China negatively. Makes you wonder how the process looks when the decision making is going on. As well, whether the opposite happens for stories which they might want to show favourably, with additional saturation or whatnot.
There’s a famous book that goes into the details of this process, you may have even heard of it, Nineteen Eighty-Four by George Orwell.
