>> The US issuing a stern warning against North Korea.>> As we hear reports that North Korea might be preparing for another missile test. I hope that does not happen, but if it does, we must bring even more measures to bear on the North Korean regime.>> The warning comes a day after Kim Jong-un's New Year's Day speech, in which he said he was open to dialogue with Seoul, while also touting his ability to hit mainland US with his nukes.
Reuters correspondent David Brunnstrom.>> Well, the United States and President Donald Trump have put a lot of effort into trying to unify countries around the world to toughen sanctions against North Korea. The concern at the State Department and in US administration, generally, will be that any talks with North Korea at this stage will be premature and run the risk of weakening that international solidarity.
>> Officials from the Trump administration on Tuesday casting doubt on Kim Jong-un's motives.>> Kim Jong-un may be trying to drive a wedge of some sort between the two nations, between our nation and the Republic of Korea. I can assure you that, that will not happen, that will not occur.
We are very skeptical of Kim Jong-un's sincerity in sitting down and having talks.>> And UN Ambassador Nikki Haley said the US would not take any talks between North and South Korea seriously, if Pyongyang refuse to give up its nuclear weapons.>> We will never accept a nuclear North Korea.
>> President Trump also weighed in as he usually does on Twitter, writing quote, Rocket man now wants to talk to South Korea for the first time. Perhaps that is good news, perhaps not. We will see. South Korea has offered to start talks next week. And while the initial focus will be North Korea's participation at the upcoming Olympics, the topic of denuclearization will likely be on the agenda.
