China signed a global pact Monday to regulate arms sales that has been rejected by the United States, the Asian power's UN ambassador said. The statement added that Beijing allows arms exports only to sovereign states and not to non-state actors. China, the second-largest global arms producer, announced June 22 it would join the Arms Trade Treaty, which now has 107 member states and designed to control the flow of weapons into conflict zones. Adopted by the UN in 2013, the treaty requires members to keep records of international transfers of weapons and to prohibit cross-border shipments that could be used in human rights violations. The arms included range from handguns to missiles to airplanes and warships.
