This is where colonies would vote to implement economic sanctions(sanctions can not be placed on colonies with "united earth base" ) . In order to act upon any issue, the majority of votes would have to read yes. The amount of votes you get depends on your gdp.
you mean, against other players colonies? No, I don't like the idea, the risk of abuse is too high. People could implement sanctions just because they don't like you.
Main colony:
human - Eldia: 0tThkRFL
human - Gondwana: MQGtwWQR
insectoids - Deinonychus: fQ3oqKnA
