No offense, but are you guys really THAT dense or did you not watch/listen at all to the video. Let me break it down for you:
They lift an export ban on weapons WHILE spitting on the dollar and making A DEAL WITH CHINA SIMILAR TO THE ONE CHINA MADE WITH RUSSIA. They will now deal with each other in their own currencies further declining the dollar.
As to who would get the weapons, probably more likely military hardware and tech not small arms, it states that CHINA is Japan's biggest trading partner.
Seems to me like what this video says is that Asia is "circling the wagons".
