Washington's top nuclear envoy said on Monday that he discussed with his South Korean counterpart humanitarian aid for North Korea and expressed hope that the North would return to dialogue. 

U.S. Special Representative Sung Kim made the remarks after talks with South Korea's Special Representative for Korean Peninsula Peace and Security Affairs Noh Kyu-duk in Washington. 

Kim said that the two sides exchanged views on the situation, as well as some ideas and initiatives for engagement, including possible humanitarian assistance. 

The U.S. envoy said they also reaffirmed their shared commitment to pursuing the complete denuclearization of the Korean Peninsula through diplomacy, adding he looks forward to hearing back from Pyongyang. 

Noh said that Seoul and Washington have held discussions on areas where they can jointly pursue a North Korean humanitarian assistance program, as well as inter-Korean cooperation projects. 

The envoy said they held follow-up discussions on those issues in the meeting as well and will continue their close consultation.
