Greece police say the rocket that hit the embacy was chinese made, makes you wonder how a terrorist group would get a chinese made rocket although china says it is careful with arms salesrocket was chinese-made
Well, I'm sure chinese stuff leaks out all of the time. I mean if you look merely at computer malware that leaks out of that country it isn't hard to imagine. And besides, plenty of stuff is "Made in China" in this country. That doesn't mean too much, unless the chinese government specifically sold those rockets.
Besides, it does not make much sense for China to have a hand in attacking a US embassy, especially in Greece. Greece has said they have problems with radical terrorists in that area in the past though.
