Western Cooperative Organization
The Western Cooperative Organization was a pact between HJE, Wayrest, Pripyat, Columbia, and Königsberg to "encourage trade, activity, respect for sovereignty, and to provide mutual security." [1]
Its fundamental idea was that the parties wished to remain uninvolved in polarized server-wide conflicts.
The pact included mutual security and defense cooperation, regular meetings between heads-of-state, common Iron/Diamond/Emerald exchange rates and tool/armor prices, and establishing a rail network to connect the member states.
