CND has been contacting embassies in London of countries that have signed but not ratified the global ban. In response to our inquiries, the embassy of Indonesia responded stating:

“Dear xxxxxxxx,

Many thanks for your email and interest in Indonesia’s perspective on the Treaty on the Prohibition of Nuclear Weapons.
The Indonesian government is very clear in its commitment to implement the three pillars of the Nuclear Proliferation Treaty. Hence, we are among the first countries to sign to the Treaty on the Prohibition of Nuclear Weapons.
The current global situation has indeed become a challenge in pursuing disarmament and nuclear non-proliferation, particularly with the ever-increasing geopolitical tension. However, we remain committed to play a pivotal role in facilitating international initiatives to achieve general and complete nuclear disarmament just as we did with the Non-Aligned Movement Working Group on Disarmament and the creation of the South East Asia Nuclear Weapons Free Zone (SEANWFZ).
As we take up the non-permanent membership at the UNSC from 2019-2020, where Indonesia sets its priorities on strengthening peace ecosystem to support world peace; synergy with regional organization; cooperation to fight against terrorism, extremism, and radicalism; and to promote sustainable development, some objectives are designed for each priority and shall be in conformity with the aim and purpose of UNSC.
Regarding the Treaty on the Prohibition of Nuclear Weapons, we would like to inform you that Indonesia is on the progress of the ratification process. Currently, the Government of Indonesia is preparing necessary documents for the process. We want to ensure that all domestic stakeholders concerned are consulted so that the treaty is inclusive and once ratified, the treaty will be properly implemented within our domestic system.
On the same time, we are also keen on hearing from you regarding your representatives to the P5 countries on the subject. We look forward to the further information from you.
Thank you.

Yours sincerely,


Embassy of the Republic of Indonesia
