With higher levels of technology, the Neruda Envoys can even make use of tariffs to increase trade for both factions or collect donations for a worthy cause. The TEC, for instance, can create Neruda Envoy ships that can be sent to improve relations with nearby planets. Beyond that, in keeping with the overall approach of the entire game, each of the three races has their own unique approaches to diplomacy. Near the top of each faction's research trees is a technology that eliminates any racial penalties that might dampen negotiations. All factions have three levels of basic relations to research, which can give them slightly better results when negotiating.
To get to the heart of the new expansion, players will really need to dive into the new Diplomacy tech tree.
