Blockade

Blockaded Companies

For companies outside a Superpower's home territories to be able to transfer their production back to the owning Superpower, they are required to have a friendly port to enable Sea/Ocean shipping of the resources. No overland shipping is allowed. A friendly port is one where the Superpower owns both the adjoining Sea and Land territory, or one is Neutral (i.e. not occupied by Warlords or Pirates), or the Superpower that owns the adjoining territory has granted Right of Passage.
