Not really recent. I read Bloomberg often and don't notice a concerted effort to make China look bad. Negative stories come out regularly and not infrequently but that should be considered normal. There are just as many non negative stories and quite a few positive ones as well. What I will agree with though is that the negative ones have a way of making their way to HN while the positive ones don't. That's really disappointing but that's what HNers up vote so would not blame Bloomberg for this.
