The U.S. has missed another key meeting of the Convention on Cluster Munitions in Oslo. It has never attended a meeting of the convention, even as an observer. The U.S. sat out the "Oslo Process" that led to the Convention on Cluster Munitions, which was born at a meeting in Oslo in February 2007 and culminated in Oslo with the Signing Conference in December 2008.  

Representatives from 121 states, including 31 observer delegations from non-signatories, attended the Third Meeting of States Parties to the Convention on Cluster Munitions in Oslo, Norway on September 11-14, as well as UN agencies, the ICRC, and the CMC. Norway's foreign minister, Jonas Gahr Støre, opened the meeting, while its permanent representative to the UN in Geneva, Ambassador Steffen Kongstad, was elected by the president of the meeting. 

In its annual report distributed to the meeting, Cluster Munition Monitor 2012, the Cluster Munition Coalition detailed progress made in implementation and universalization of the Convention on Cluster Munitions. The report notes Libya and Thailand's confirmed instances of cluster munitions use since entry into force of the convention. While this use occurred in non-states parties to the convention, it was strongly condemned by many nations.
