===Bilateral and multilateral treaties===
[[Bilateral treaty|Bilateral treaties]] are concluded between two states or entities.<ref name="nicholson135">Nicolson, Harold. (1934). ''Diplomacy,'' p. 135.</ref> It is possible for a bilateral treaty to have more than two parties; for example, each of the bilateral treaties between [[Switzerland]] and the [[European Union]] (EU) has seventeen parties: The parties are divided into two groups, the Swiss ("on the one part") and the EU and its member states ("on the other part"). The treaty establishes rights and obligations between the Swiss and the EU and the member states severally—it does not establish any rights and obligations amongst the EU and its member states.{{citation needed|date=November 2010}}

A [[multilateral treaty]] is concluded among several countries, establishing rights and obligations between each party and every other party.<ref name="nicholson135"/> Multilateral treaties may be regional or may involve states across the world.<ref>{{cite web|title=Multilateral Treaties/Agreements|website=refworld.org|date=2013|url=https://www.refworld.org/type,MULTILATERALTREATY,SAARC,,,,0.html|access-date=20 July 2019|archive-date=20 July 2019|archive-url=https://web.archive.org/web/20190720070951/https://www.refworld.org/type,MULTILATERALTREATY,SAARC,,,,0.html|url-status=live}}</ref> Treaties of "mutual guarantee" are international compacts, e.g., the [[Treaty of Locarno]] which guarantees each signatory against attack from another.<ref name="nicholson135"/>
