Echo 7-7, even without Embargo, do you realise that you can't transport H-Fuel and Plutonium on your IC through Kusari?:D
It's restricted to Samura and Kishiro, by an arrangement done with GMG, so with or without embargo... IC with H-Fuel or Plutonium in kusari is a no go:P
Edit: That's is if you are IC... just now I saw your signature... but Ageira is the same, can't get their hands on those 2 commodities.
EDITED again:
One way to get this solved would be if those trading faction interested in those items start pocking liberty's government to clean this mess.
Why do I suggest Liberty's and not Kusari's? Kusari is way too stubborn to solve this without Liberty letting go.
On that note: How is a government not controlled by that country's industries? Most of laws in Kusari are done for/by Kishiro and Samura and their influences, just those concerning piracy, capital ships free pass, and some other less important are done by KNF or KSP exclusively.
Which leads me to another point that I always had in my mind, which is Liberty's government (for my understanding, I can be wrong on this, as I never took part of it) not influenced by their companies, or doesn't seem so.
But, for sure, the lack of pressure from liberty's companies on their government about this matter, is another factor encouraging this embargo to not be lifted.
So, now, if you see it from my point of view, it's a fight of Egos, it's like USA movies where two cars run to eachother head to head, I believe it's called "play chicken".
