Arms treaty conference fails to set reporting rules in Mexico

CANCUN, Mexico (Reuters) - Countries backing a major accord to regulate the international arms industry on Thursday failed to agree on a definitive format for reporting arms sales, kicking the issue down the road and disappointing advocates of arms control.

Officials from 121 governments have been meeting in the Mexican resort of Cancun to agree details of how the Arms Trade Treaty (ATT) will oversee the multi-billion dollar industry.
