Treaty with positive embargo effect

Country A, B choose to sign together.

They link a list of sectors. If A choose Tech and B choose Oil, both get extra points depending on number of population and demand (if country B lacks a lot of tech, they”ll buy it so A gets money in budget and more GDP, while B spend money but people are more satisfied). and it can concern more than 2 people;

HOWEVER, laws of a specific sector must be locked and can be unlocked only if all members agree (otherwise, the treaty must be deleted)
