It doesn't necessarily seem as though the Chinese government is behind this.

Look at what actually happened: Somebody called in a bomb threat under her name, and somebody made some fake reservations under that name at a hotel near the location they were "threatening."

...That's the sort of thing a bored teenager on 4Chan or KiwiFarms would do, without even breaking a sweat. There's nothing in the article to suggest that the Chinese government is behind this; their only action was to report the bomb threat as though it was credible. The threat itself probably came from some terminally-online, but patriotic, expat Chinese ne'er-do-well.
