I can do food for sure, I have 2 nice flood plains for farming various foodstuffs, mostly grains like rye as well as cattle and poultry. The terrain is also good for soft woods so while i cannot provide stuff like oak I can give you maple, ash, and walnut style wood. I am thinking bauxite, copper, and silver would be good my main minerals of note besides iron and coal of moderate quality and quantity for my nation. I note you said nothing of naval ships, would you be interested in purching naval ships of any kind? 

I have good production capability already though could certainly use high quality steel and coal. My oil production I was thinking was around sufficient so I will likely want to import some oil as well.

I actually had an idea to have a slowly developing wine industry in my nation perhaps your nation might be interested in investing in that to accelerate the growth of that industry. 

Clockwork I am really looking at in my nation and I think maybe that it could be cool if your nation was trying to sell my nation on the idea of it. Currently my nation relies on pistons and hydraulics and that could prove an interesting point to RP out.

I realize i am kind of rambling. I like writing up nation interaction stuff and generally just throw stuff out there so tell me what you think of what I have here.
