Annex 2 States
“Annex 2” States are the states that must ratify the Treaty for the CTBT to enter into force. These 44 states are those that participated in the negotiation of the CTBT from 1994-1996 and that possessed nuclear power or research reactors at the time.
There are nine Annex 2 States that have yet to ratify the Treaty - China, Egypt, Indonesia, Iran, Israel, and the United States of America, which have signed the Treaty, and North Korea, India, and Pakistan, which have not signed.
Progress Toward Ratification
-
President Obama announced his intention to pursue U.S. ratification of the CTBT in April 2009.
-
In May 2010, Indonesia announced its support for the CTBT and is currently pursuing ratification in its legislature.
