Very little on the trade front as there's not much to trade yet.
The only possible trades are tech trades. The following is a notice to the Science Department for possible review during the turn chat:
Russia, Japan, America and India are willing to give all of their gold for either alphabet or iron working. The Aztecs are broke, and America and India have less than 25g. England still refuses to trade. That's a total of 180g - enough for 4 warrior to swordsman upgrades.
