Representatives for the United Nations Conference on the Arms Trade Treaty arrived in New York Sunday.
The conference is set for July 2-27.
The UN has operated a Register of Conventional Arms since 1991. In advance of the meeting, the UN announced the types of arms registered is being expanded.
“The Register covers seven categories of arms, which are deemed the most lethal ones,” according to the UN. “Recently, countries decided that small arms could be added to the Register. Many countries now include small arms in their yearly reports.”
