South Korea’s President on Thursday promised to open the door to a “new Korean peninsula” through achieving a peace economy and working to “solidify” efforts towards North Korea’s denuclearization.

In a speech marking the 74th anniversary of the end of Japanese rule in Korea, Moon Jae-in reiterated Seoul’s goal of establishing peaceful economic cooperation with the North and completing the country’s liberation through the unification of the peninsula.

“As we commemorate the Liberation Day today, I pledge to solidify denuclearization and peace regime on the Korean Peninsula during my term in office,” Moon told an audience at the Independence Hall of Korea in Cheonan.
