On 25 November 2014, H.E. Mr. Norachit Sinhaseni, Ambassador Extraordinary and Plenipotentiary, Permanent Representative of Thailand to the United Nations, signed the Arms Trade Treaty (ATT) at the United Nations Headquarters in New York, as witnessed by Ms. Angela Kane, UN High Representative for Disarmament Affairs, and Mr. Santiago Villalpando, Chief of Treaty Section of the UN Secretariat. In this regard, Thailand becomes the 123rd Signatory State to the ATT. At present, 54 UN member states have ratified the ATT, which will enter into force on 24 December 2014. Thailand signed the ATT to affirm its political will in becoming a State Party to the Treaty in the future.

The Arms Trade Treaty was adopted by the United Nations General Assembly on 2 April 2013 (GA resolution A/RES/67/234 B) in order to establish international standards for regulating or improving regulations of international trade in conventional arms as well as to prevent and eradicate illicit trade in conventional arms and to prevent their diversion, which has long since fueled transnational crime, the deprivation of freedom, and human rights violations.
