Hmmm.
According to this (supplied by the ever faithful Fred (ah, but is he?)), China has been financing military acquisitions, by selling nasty stuff to the Arabs. Seeing as Israel seems to have been selling military equipment to China, this creates a rather awkward situation, whereby China has been biting the hand that sells it weapons. Maybe they don't realize that they won't get any spare parts if their supplier is gassed.
Oy! The people we have to do business with to make a living!
