The Kingdom of the Netherlands recognized the Republic of Estonia on 5 March 1921. After the Estonian restored independence the Netherlands (re-)recognized the Republic of Estonia on 2 September 1991. Diplomatic relations were restored on 21 September 1991.
It was complicated for the Cabinet of Ministers of the Kingdom in 1991 to recognize the restoration of independence of Estonia because the Netherlands had not made a reservation for the annexation of Estonia in 1942 while recognizing the Soviet Union (SU). This basically means that the Netherlands had recognized Estonia as part of the SU. The Netherlands (and Spain) were exceptional in that regard, because most of the European Community member states had had diplomatic relations with the SU already before the annexation of Estonia in 1940 – for which they had made a reservation in their relations with the SU. This issue has even been mentioned as an example of controversial state succession by a Dutch study book of international law in 2007 (Handboek Internationaal Recht).
