EIDA helps to solve conflicts through diplomatic advising.  The EIDA projects that deal with diplomacy vary from case to case.

Micronations
In emerging micronations, EIDA works closely with foreign ministries to set up sound foreign policies.  Then, EIDA helps governments to
network with other nations according to a set FPDP (Foreign Policy Development Plan). EIDA assists nations in formulating a FPDP that takes into account their size, potential, culture, economics, and goals.  By offering FPDPs to new micronations, EIDA fosters the growth of these nations and inftroduces them to the international community.  In the process of acceptance, EIDA will take a more passive role, allowing the new government to handle its foreign affairs based on its own judgement.
Another aspect of EIDA's diplomacy programs in micronations includes the
DNS (Diplomacy and Negotiation Seminar).  Working with both macro and micronational organizations, EIDA helps foreign ministries gain knowledge and experience about the field of micronational diplomacy.  The seminars offered to nations include an introduction to the micronational international system, multilateral organizations and their politics, online forums, discussions, and emails, protocol, preventive diplomacy, and negotiation techniques.
In cases where countries are being mistreated by larger and older micronations, EIDA may serve as a lobbyist or mediator, so long as both parties comply.  This function can also be requested by any two micronational parties in conflict through the
Department of Foreign Affairs of Eslo.

Macronations
Real world diplomacy is harder to get involved as a micronation.  However, EIDA supports a number of activities that promote diplomacy as a means of solving disputes peacefully.  Some projects that EIDA formally sponsors are: the World Model United Nations, United Nations Online, University of British Columbia United Nations, Toluca Model United Nations, Baur International Model United Nations, ITAM Model United Nations, and Harvard National Model United Nations.
In addition, Eslonian diplomats are encouraged to attend events and contribute to campaigns organized by the Carnegie Endowment for International Peace, the
Council of Foreign Relations, The Fraser Institute, the Morris Wosk Centre for Dialogue, Toastmasters International, and Medicins Sans Fronteres.
On a regular basis, EIDA will promote specific policies in general international relations.  These policies are often presented before various social and political groups.
