I'm looking for two nations with water, gold, wheat, or aluminum to repair a Affluent Population, Fine Jewelry, Beer Ring. This trade ring is probably the best or second best ring in the game (I think it's a little better than Aff Pop/Fine Jewelery/Fast food since it decreases your infrastructure cost a lot more and also contains water). It really maximizes your income and you can also temp trade for construction. It has fish and wheat and uranium.
