The instrument of ratification of the Treaty by the Netherlands states that the Treaty is approved for the Kingdom in Europe, Surinam and the Netherlands Antilles.
Suriname became an independent state on November 25, 1975.
The Royal Netherlands Embassy in Washington transmitted to the Department of State a diplomatic note, dated January 9, 1986, which reads as follows:
“The Royal Netherlands Embassy presents its compliments to the Department of State and has the honor to request the Department’s attention for the following with respect to the Department’s capacity of depositary of [the Treaty on the Non-Proliferation of Nuclear Weapons].
“Effective January 1, 1986 the island of Aruba – formerly part of the Netherlands Antilles – obtained internal autonomy as a country within the Kingdom of The Netherlands. Consequently the Kingdom of The Netherlands as of January 1, 1986 consists of three countries, to wit: the Netherlands proper, the Netherlands Antilles and Aruba.
“Since the abovementioned event concerns only a change in internal constitutional relations within the Kingdom of The Netherlands, and as the Kingdom as such, under international law, will remain the subject with which treaties are concluded, the aforementioned change will have no consequences in international law with regard to treaties concluded by the Kingdom, the application of which (treaties) were extended to the Netherlands Antilles, including Aruba.
“These treaties, thus, will remain applicable for Aruba in its new status as autonomous country within the Kingdom of The Netherlands effective January 1, 1986.
“Consequently the [Treaty] to which the Kingdom of the Netherlands is a Party, and which [has] been extended to the Netherlands Antilles will as of January 1, 1986 apply to all three countries of the Kingdom of The Netherlands.
“The Embassy would appreciate if the other Parties concerned would be notified of the above.
“The Royal Netherlands Embassy avails itself of this opportunity to renew to the Department of State the assurance of its highest consideration.”
The Royal Netherlands Embassy in Washington transmitted to the Department of State a diplomatic note, dated October 6, 2010, which reads in pertinent part as follows:
“The Kingdom of the Netherlands currently consists of three parts: the Netherlands, the Netherlands Antilles and Aruba. The Netherlands Antilles consists of the islands of Curaçao, Sint Maarten, Bonaire, Sint Eustatius and Saba.
“With effect from 10 October 2010, the Netherlands Antilles will cease to exist as a part of the Kingdom of the Netherlands. From that date onwards, the Kingdom will consist of four parts: the Netherlands, Aruba, Curaçao and Sint Maarten. Curaçao and Sint Maarten will enjoy internal self-government within the Kingdom, as Aruba and, up to 10 October 2010, the Netherlands Antilles do.
“These changes constitute a modification of the internal constitutional relations within the Kingdom of the Netherlands. The Kingdom of the Netherlands will accordingly remain the subject of international law with which agreements are concluded. The modification of the structure of the Kingdom will therefore not affect the validity of the international agreements ratified by the Kingdom for the Netherlands Antilles; these agreements will continue to apply to Curaçao and Sint Maarten.
“The other islands that have until now formed part of the Netherlands Antilles – Bonaire, Sint Eustatius and Saba – will become part of the Netherlands, thus constituting ‘the Caribbean part of the Netherlands’. The agreements that now apply to the Netherlands Antilles will also continue to apply to these islands; however, the Government of the Netherlands will now be responsible for implementing these agreements.”
