The five nuclear weapon states nder the terms of the Treaty on the Non-Proliferation of Nuclear Weapons (United States, Russia, United Kingdom, France, China) have all ratified or signed the CTBT; the others stated in the question have not.

Poor question as 5 countries signed to ratify the treaty. Another 66 signed later and it is something like 180 countries have now signed.
