For now we must continue to strengthen our sanctions and pressure on North Korea.

Humanitarian assistance and exchanges are still allowed, even under the sanctions regime on North Korea. Therefore, in parallel with sanctions and pressure, we must also employ humanitarian assistance. The meeting of separated families is also a measure to ensure human rights.

Korea and the U.S. have maintained a combined forces command system for a long time. Even if we were to get operational control back, as long as this combined system is maintained, our countries will continue to have combined security, and U.S. forces will continue to play their part in our security.

President Trump also mentioned that under the right conditions, he is willing to engage in dialogue with North Korea.

What Korea and the U.S. both ultimately seek to achieve is the dismantlement of North Korea's nuclear program.

As long as North Korea continues its provocations, I believe that we will have no choice but to apply additional and strong pressure on it. At the same time, it is also important to send out a message to North Korea that if it decides to denuclearize and to come to the negotiating table, then we are willing to assist them.

The message that we must send to North Korea is twofold: If the North Korean regime believes that it can defend and protect itself through nuclear and missile programs, that is a misjudgment. But if North Korea gives up its nuclear program, we will help it secure and develop itself. We must consistently send these two messages.

Every time North Korea commits an additional provocation, the U.N. Security Council passes another resolution. But when it comes to dialogue, currently there is nothing set. I hope to have frank and open discussions with President Trump on this issue.

It is very deplorable that North Korea still does not uphold human rights, which are universal values.

Kim Jong Un is an unreasonable leader and a very dangerous person. Yet he is the person who has effective control over North Korea, and he is the person who has the authority to denuclearize North Korea.

As a sovereign state, we should have operational command of our forces returned to us at an appropriate time. Korea and the United States have already reached an agreement where we will receive operational control of our forces when the conditions are met.

When it comes to dialogue between South and North Korea and between the United States and North Korea, these can go on parallel tracks. South Korea and the United States can each play a role.
