Newly appointed U.S. Ambassador to South Korea Harry Harris says lifting sanctions on North Korea is possible only after denuclearization and trust-building.

Harris met with Korea Institute for International Economic Policy President Lee Jae-young Tuesday.
 
He emphasized that the North’s implementation of denuclearization will provide the regime with an opportunity for development.
 
Lee expressed hope that a formal declaration to end the Korean War will help build a peace regime on the Korean Peninsula. He also proposed that South Korean and U.S. research institutes push for joint research projects for multilateral cooperation in Northeast Asia.
