"I probably have a very good relationship with Kim Jong-un", Mr Trump told The Wall Street Journal.
The North Koreans also expressed their surprise over the popular opinion in South Korea that U.S. President Donald Trump would never start a war in Korea and that the tension, crisis-like atmosphere and belligerent rhetoric are all posturing, according to Vorontsov.
Technically, South Korea and the United States remain at war with North Korea after the Korean War ended in 1953 with an armistice instead of a peace treaty.
And the newspaper, a mouthpiece for Kim and his tyrannical government, said Fire and Fury's popularity reflected 'rapidly surging anti-Trump sentiments in the worldwide community'.
According to the narrative put forth by those advocating a tougher response, a strike could be limited to a single target with the aim of making Kim see reason, not to topple his government, something North Korea's neighbor and only major ally, China, would not countenance, the officials said.
Direct talks between the USA president and Kim would be unprecedented. The Russian president said the North Korean leader is likely to be seeking an easing of tensions in the region.
In November, Trump said while on a trip to Vietnam that becoming friends with Kim "might be a odd thing to happen but it's a possibility".More news: Facebook begins testing local news app
Kim Jong-un and Donald Trump have a "very good relationship", the U.S. president suggested last night, in remarks that appeared to signal a new openness to diplomacy with North Korea.
North Koreans are also genuinely anxious the United States could launch a preventive war on the peninsula. The US responded to North Korean actions by flexing its muscles and conducting a number of military drills in the region with its allies South Korea and Japan. "I'm not saying I have or I haven't".
Trump has said North Korea won't be allowed to develop a nuclear missile capable of striking the United States, and has threatened war if economic sanctions and negotiations can't avert Kim's ambitions for such a weapon. The president said this may happen if all participants in this process, including North Koreans, will be sure that their security can be guaranteed without nuclear weapons.
He said: "He is already a shrewd and mature politician".
In mid-November 2017, I spent several days in Pyongyang talking to DPRK foreign ministry officials about the prospects of war between North Korea and the United States.
The consensus among USA intelligence agencies is Kim is convinced Washington seeks to overthrow him and only a nuclear arsenal can deter that.
The result of Tuesday's talks was a joint statement from the two Koreas, which pledged further talks on the DPRK's participation in the upcoming PyeongChang Olympics, as well as on military and diplomatic issues.
