Here’s Malawi’s statement among many others included in this ICAN document on the first anniversary of the TPNW:
“The only guarantee of our security against the threat of
nuclear weapons is their complete elimination. That is
why Malawi is among the countries that signed the
Treaty on Prohibition of Nuclear Weapons in 2017. The
treaty places nuclear weapons on the same legal footing
as the other weapons of mass destruction deemed
unacceptable for their indiscriminate and inhumane
effects such as biological and chemical weapons …
Malawi is fully committed to the treaty and is looking
forward to ratifying it with an intention to become a state
party … as soon as possible.” – 12 October 2018
