Iran's negotiator, Araghchi disclosed in an interview that certain elements of the interim agreement are fleshed out in a secret 30-page "side agreement" or "nonpaper." He said it included information about the operation of a joint commission to oversee the interim agreement's implementation. State Department spokeswoman Marie Harf denied later that there was any secret agreement. The text of the implementation agreement was not released to the public. US National Security Council spokeswoman Bernadette Meehan said that this is because the EU is not making the document public." The White House released a summary of technical understandings related to the implementation of the agreement on 16 January.
