The leaders also discussed their vision for NATO's future role in global security, including how to combat emerging threats like cyber security, Obama said.
Obama said Rasmussen would identify the host country for the 2014 summit, which will look at building up NATO's ability to address cyber threats and "lock in" commitments by members.
"That requires burden-sharing on the part of all NATO members. It means that even during times of austerity, that we work smarter together to ensure that we can meet and are prepared for any threats that may arise," Obama said.
