South Korean National Security Adviser Chung Eui-yong discussed denuclearization issues with U.S. Special Representative for North Korea Stephen Biegun Friday in Seoul. 

Presidential Spokesman Kim Eui-kyeom said they also had a broad discussion on cooperation projects with the North, including humanitarian assistance for the regime. 

Earlier, Biegun told his South Korean counterpart Lee Do-hoon the U.S. would look at the issue of humanitarian assistance for the North next year, possibly loosening a travel ban for certain American humanitarian groups.
