Who signed, and when

Participants that are UN member states link to their profile. The Holy See, the European Union, the Cook Islands and Niue appear in these tables and are not member states, so they are named without a link rather than attached to the nearest match. The third column carries the depositary’s own annotation. Accession, succession and acceptance are legally distinct from ratification and are shown as the record states them rather than flattened into one word.
