The Vienna Convention on the Law
of Treaties
 (VCLT) is a treaty concerning
the 
international law on treaties between
states. It was adopted on 22 May 1969
[1] and
opened for signature on 23 May 1969.
[2] The
Convention entered into force on 27 January 1980.
[2]

As of January 2018, 116 state parties have ratified the
convention, and a further 15 states have signed but have not ratified the convention.
[3] In
addition, the 
Republic of China (Taiwan), which is
currently only recognized by 
14 UN member
states
, signed the Convention in 1970 prior to the United Nations General Assembly‘s vote to transfer
China’s seat
 to the People’s Republic of China (PRC) in 1971. When the
PRC subsequently acceded to the Convention, they described the Republic of
China’s (ROC) signature as “illegal”.
[3] 65 UN
member states
 have neither signed nor ratified the Convention.

The Republic
of China

states
, signed the treaty prior to the United Nations General Assembly‘s vote to transfer
China’s seat
 to the People’s Republic of China (PRC) in
1971. When the PRC subsequently acceded the treaty, they described the Republic
of China’s (ROC) signature as “illegal”.[3]
