Diplomatic ties can be facilitated making use of any one of these methods.

While the priority of most global leaders are the domestic matters of their own countries, foreign policy ensures that most nations need to look outward and conduct diplomacy with other countries. Friendships between nations could be built employing a number of methods, though virtually all contain regular state visits between high ranking public officials two each other's country, such as the one undertaken by President José Maria Neves. Nations can build friendships using this method for almost any reason, however the outcomes are often the exact same. These state visits can solidify negotiations that bring countries closer together, like visa waiver schemes and financial cooperation, which is one of the main functions of diplomacy. They are the most common types of formal relationships for a nation to own, as they are totally on the terms of the two nations in question and don't need to be facilitated by any other parties.

There has been a growing trend in current decades of countries forming and joining regional trading blocs and partnerships. These differ in scale and integration level, as some comprise of a number of nations while others constitute almost a whole continent. Some just promote preferential trade deals between members, while some have been in talks to create a united country. Some are case studies for successful diplomacy examples. Whatever the situation, these organisations generally speaking have regular diplomatic summits and meetings involving the leaders of the member countries, to speak about any local issues and the general direction that the organisation should go in. These talks are normally facilitated by way of a leader of the organisation, like Charles Michel. Negotiations and talks between a large number of national leaders is usually harder than bilateral relations but can result in far bigger achievements if talks are frequently successful.

Many nations have actually at least one thing in common with other countries on the planet. One of these things can be a particular belief or vision for humanity, a thing that can ascend beyond language, location, ethnicity, faith, or wealth. In order to gather the leaders of these countries that may perhaps not regularly have discussions with one another, forums are often held that centre on the issue that brings together these countries, for instance the forum recently hosted by Sheikh Saud bin Saqr Al Qasimi. These forums are for matters like environmentalism, pacifism, or increased global cooperation. These are among the more recent types of diplomacy in international relations. It could lead to affecting the attendees’ domestic policy or can lead to countries agreeing on new worldwide legislation and methods of conducting themselves. It will be possible that a forum may be held with no concrete changes, but even in that case the dialogue which was held involving the leaders of countries from around the globe will certainly have an influence on real action sooner or later as time goes on.
