Accord, annex, charter
, memorandum of understanding, protocol
, etc., which (as defined by the Vienna Convention
On The Law Of Treaties) is an "agreement concluded between states in written form
and governed by international laws, whether embodied in a single instrument
or in two or more related instruments and whatever its particular designation
." The title
of the agreement
is not a determining factor
in making distinctions among different arrangements. Although considered binding, international agreements may lapse
, through war or denunciation, or when a fundamental change
in circumstances occurs.
Multilateral agreements are usually open
to all nations, plurilateral agreements involve a restricted
number of nations, and bilateral
agreements are usually private arrangements between two nations.
