The Principality of Liechtenstein will accordingly participate, so long as the said Treaty remains in force, in the international Conventions which have been or may hereafter be concluded in the matter of narcotic drugs, it being neither necessary nor advisable for that country to accede to them separately."5See note 1 under "Bosnia and Herzegovina", "Croatia", "former Yugoslavia", "Slovenia", "The Former Yugoslav Republic of Macedonia" and "Yugoslavia" in the "Historical Information" section in the front matter of this volume.6In a notification received on 21 February 1974, the Government of the German Democratic Republic stated that the German Democratic Republic had declared the reapplication of the Convention as from 7 April 1958.

Subsequently, in a communication received on 17 June 1976, the Government of the German Democratic Republic declared: "The Government of the German Democratic Republic takes the view that in accordance with the applicable rules of international law and the international practice of States the regulations on the reapplication of agreements concluded under international law are an internal affair of the successor State concerned. Accordingly, the German Democratic Republic was entitled to determine the date of reapplication of the International Opium Convention, February 19th 1925 to which it established its status as a party by way of succession."
