Historic Two Days for CTBT at Article XIV Conference

States Urged to Seize Momentum at Historic CTBT Conference

(Article XIV Conference)

"The momentum is rare, and we must seize this momentum," stressed the UN Secretary-General Ban Ki-moon at the sixth Conference to promote the entry into force of CTBT. The participation of U.S. Secretary of State Hillary Clinton was particularly significant. It was seen as demonstrating the United States' renewed commitment to nuclear non-proliferation and disarmament. "We will work in the months ahead both to seek the advice and consent of the United States Senate to ratify the treaty," Clinton said and conluded her address by saying: "We are happy to be back". Speakers also included U.N. Messenger of Peace Michael Douglas who proclaimed that "there is a new wind blowing." There were repeated calls on countries to take advantage of the political momentum and to complete the requirements needed for the treaty's entry into force, i.e. to sign and ratify the Treaty. Particular mention is being made in this regard of hopeful signs coming from China, Indonesia and the United States.  The final declaration adopted by consensus was then brought to the doorstep of a UN Security Council summit on nuclear non-proliferation and disarmament.
