AP - The United Arab Emirates has seized a cargo ship earlier this month bound for Iran with a cache of banned arms from North Korea, the first such seizure since sanctions against North Korea were ramped up, diplomats and officials told The Associated Press Friday.
I don't think they can go ahead and sell the contents on that ship.
I'm not sure what the UN's SOP on seized weapons are but resale seems somewhat unlikely. Most likely destruction after careful documentation.
Just speculating here but I don't imagine the UAE would ever sell that stuff. They may never fully disclose what's there either simply because doing so could shed light on their own arms dealings.
