I must note that China has political and economic power that comes with enemies. The world is beset by malignant actors, and for most of a century that malevolence has included biological pathogens. While it is impossible to prove any particular provenance of some pathogen China has suffered, it is undeniable that the present circumstances in China involving not only the Kung Flu, but bird flu and swine flu, as well as the constant threat of a resurgence of plague, and now the arrival of a swarm of locusts on it's border, have generated much speculation that some of that pathogenicity results from malice, and not natural sources.

Thanks!
