On 17 September 2013, the Union Minister for Foreign Affairs of Myanmar, H.E. U Wunna Maung Lwin, and IAEA Director General Yukiya Amano signed an Additional Protocol to Myanmar's safeguards agreement at the IAEA Headquarters in Vienna, Austria.

The Additional Protocol is a legal document that, when concluded with States with comprehensive safeguards agreements (CSAs), equips the IAEA with important additional measures that provide for broader access to information about the State's nuclear programme, increased physical access by IAEA inspectors and improved administrative arrangements. The implementation of an Additional Protocol significantly increases the IAEA's ability to verify the peaceful use of all nuclear material in States with CSAs in force. There are currently 121 States with Additional Protocols in force.

The AP for Myanmar will enter into force on the date on which the IAEA receives from Myanmar written notification that Myanmar's statutory and/or constitutional requirements for entry into force have been met.
