South Korean President Yoon Suk-yeol outlined new details of his vision to improve North Korea’s economy and soothe inter-Korean tensions if Pyongyang takes “genuine and substantive” steps toward denuclearization.

The president made the remarks during a Liberation Day speech in Seoul on Monday, saying his country could offer a “large-scale food program,” overhaul the DPRK’s air and sea ports, enhance agricultural productivity, strengthen health care infrastructure and even attract foreign investment.
