UNEP received a note verbale on 1 October 1990, from the Permanent Representative of the Federal Republic of Germany to UNEP to the effect that through the accession of the German Democratic Republic to the Federal Republic of Germany with effect from 3 October 1990, the two German States have united to form one sovereign state. As from the date of unification, the Federal Republic of Germany will act in the UN under the designation of Germany. The applicable dates of ratification and entry into force are those of the Federal Republic of Germany. The German Democratic Republic had acceded to the Convention on 25 January 1989. A similar note verbale was received by UNEP in respect of the Montreal Protocol.
