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.

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.

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.

During the periods when South Korea played a more active role, the inter-Korean relationship was more peaceful, and there was less tension between the United States and North Korea. The last U.S. administration pursued a policy of strategic patience and did not make any effort to improve its relationship with North Korea. Also, the previous Korean government did not make any such efforts. The result is the reality you see today - North Korea continuing to advance its nuclear and missile program.

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

North Korea continues to advance its nuclear technology and will soon reach weaponization. Regarding its intercontinental ballistic missiles, it is continuously making progress. So currently, it is urgent for us to freeze North Korea's program so they will stop additional provocations and stop advancement of its technologies. I believe during my upcoming summit meeting in the U.S. I will be able to discuss a two-phased approach to the North Korean nuclear issue - the first being a freeze and the second being complete dismantlement.
