The Treaty on the Prohibition of Nuclear Weapons (TPNW) entered into force on 22 January 2021. Article 8, paragraph 2, of the Treaty specifies that "the first meeting of States Parties shall be convened by the Secretary- General of the United Nations within one year of the entry into force of this Treaty."

Originally scheduled to be held in January 2022, States Parties subsequently decided to hold the Meeting from 21 to 23 June 2022 at the Austria Center Vienna. On 4 April 2022, the Secretary-General of the United Nations circulated a note verbale convening the Meeting of States Parties and inviting States not party to the TPNW to attend the Meeting as observers (available in EnglishFrançais & Español).

Information for Participants

Information for representatives of States and international organizations

The revised information note for States parties, observer States and intergovernmental organizations (TPNW/MSP/2022/INF/1/Rev.1) has been issued. Delegates are requested to review the information contained therein in detail. The attention of delegations is particularly drawn to revisions in sections II, III, V, VI and VIII and IX, as well as the new section VII.

All members of delegations to the Meeting of States Parties, irrespective of whether they are already in possession of a grounds pass to the United Nations Office in Vienna, are requested to register using the form available at https://forms.office.com/r/FeLZA8yuPq no later than 14 June 2022. All delegates will receive a special conference pass, which will allow them entry to the Meeting of States Parties. Registrations can only be processed for members of delegations who are included either on their delegation’s list of participants or on the list of credentials (see sects. IV and V above).

Delegates will receive an email confirming their registration within 1–2 days of submitting the online form. They will subsequently receive a second email containing a link that will enable each participant to upload a photograph, which is needed to issue a pre-printed conference pass and which will therefore shorten the time needed to issue an access pass on the day of registration.

Identification passes will be issued at Gate One of the Vienna International Centre. Delegates who have uploaded their picture in advance will be able to collect their pass from the area marked “Pre-printed conference passes”. Delegates who have not uploaded their picture in advance will be able to collect their pass from the Pass Office. Both places are located to the right after the entrance to Gate One. Delegates will be able to collect their passes on 20 June from 1.00pm a.m. to 3.30 p.m. Passes can continue to be collected until the end of the Meeting of States Parties on 23 June.

Permanent Mission of Kazakhstan to the International Organizations in Vienna

For more than four decades, starting from 1949, part of Kazakh land was used by the Soviet Union to test its nuclear weapons. Up to 1.5 million of our people were exposed to the nuclear fallout from the 456 explosions detonated at the Semipalatinsk nuclear test site, acknowledged as the second largest in the world.

With the relentless and unfailing support of our citizens, who protested the reckless use of their native soil that was also affecting their health and lives, the First President Nursultan Nazarbayev decided on behalf of Kazakhstan to close the test site. This historic step was taken 30 years ago on 29 August 1991. Later, Kazakhstan also voluntarily gave up the world’s fourth most potent nuclear arsenal.

In recognition of Kazakhstan’s historic decision, the UN General Assembly proclaimed the 29th of August as the International Day against Nuclear Tests.

Last year the TPNW entering into force coincided with the 30th anniversary of the closure of the Semipalatinsk nuclear test site, which we found very symbolic.

In this regard, these days of the Conference the Permanent Mission of Kazakhstan would like to present an exhibition dedicated to the closure of the Semipalatinsk nuclear test site. Prohibition of nuclear testing and nuclear weapons is the only right choice on the way to peace and stability. Kazakhstan is a prime example of this.
