Food ,fertilizer,oil,industrial machinery and so on.I wonder what NorK is getting in return? Two-three squadrons of non-export "modern" Mig-29's with upgrading their current fleet of Mig-29's sounds fair to me if I was Kim. Other thn that what does NorK really need from Russia when it comes to weapon systems?
Ok IADS is the other since NK IADS are just waaay outdated.
The list infinite.
Other side, how the USA wish to prevent any business that Russia doing with NK ?
They has common border, railway and road link, so in good case the USA can guess the business that they do with each other.
