If the proposal “Trade Routes” was enacted, add a subrule to Trade Routes called “Foreign Commerce”:

Each of the foreign powers imports one resource and exports another.
- Mycenae imports Money and exports Piety
- Sardinia imports Money and exports Livestock
- Crete imports Piety and exports Money
- Troy imports Piety and exports Livestock
- Alexandria imports Livestock and exports Money
- Heliopolis imports Livestock and exports Piety

When a Guardian owns a building in a region with an Embassy or is the Baron of a region with an Embassy, they may, as a daily action, select one such Embassy and use it to Conduct Foreign Commerce:
- Spend some amount of the resource that the Embassy’s foreign power imports.
- Gain an amount of the the resource that the Embassy’s foreign power exports equal to one third of the amount that you spent (rounded down).
