Asia-Oceania Neutron Scattering Association (AONSA) is the neutron scattering societies representing users in the Asia-Oceania Region. AONSA was established in 2008. The purposes of the Association are to provide a platform for discussion and an action focusing on neutron scattering and related topics in the Asia-Oceania Region.

The 16th AONSA Executive Committee Meeting was held on Tuesday May 31, 2016, at the China Spallation Neutron Source (CSNS) in Dongguan, China. Eighteen participants came to Dongguan for the meeting, consisting of nine Executive Committee (EC) members and nine observers representing neutron facilities in the Asia-Oceania region. In this meeting, it was the first EC meeting to include the Indonesian Neutron Scattering Society (INSS) as a formal member of AONSA. In welcoming participants to the meeting, AONSA President Sung-Min Choi thanked the organisers in Dongguan, and extended a particular welcome to Darminto, representing INSS.

In this meeting, participants discussed briefly the preparations for  the AONSA Young Research Fellowship in 2017, the 8^th AONSA school to be held in India in November 2016, the International Conference on Neutron Scattering (ICNS2017) to be held in Korea in July 2017, and the 3^rd Asia-Oceania Conference on Neutron Scattering (AOCNS-2019) to be held in Taiwan in November 2019. The meeting run smoothly. Finally, the next meetings will be held in India, Korea and Thailand for the 17^th, 18^th, and 19^th AONSA EC meeting, respectively.
