"How can we have any dialogue to get any result with anyone who has this kind of approach?" North Korea has been conducting several nuclear tests and missile launches in contravention of UNO resolutions.
The DPRK has never begged for peace but is prepared to take tough countermeasures in order to defend itself with its military might and to move down the pathway it has chosen for itself, Kim said adding that Pyongyang was going to bring the USA to account for aftermaths of the Americans' actions. Speaking to reporters, Pence said: "It is our belief by bringing together the family of nations with diplomatic and economic pressure we have a chance of achieving a freeze on the Korean Peninsula".
"The US has to come to its senses and come to the preferred option", he noted, stressing that DPRK [Democratic People's Republic of Korea] forces are ready to face any threat to the country's sovereignty. It responded to America's latest threats by firing a missile on Sunday, which exploded seconds later.
Pence made an unannounced visit to the Demilitarized Zone at the start of his 10-day trip to Asia in a USA show of force that allowed the vice president to gaze at North Korean soldiers from afar and stare directly across a border marked by razor wire.
"The United States will strengthen its presence in the Asia Pacific", he said. "The recent USA massive missile attack on Syria tells you well of it".
White House spokesman Sean Spicer said China had taken some "very helpful" steps, although it remained to be seen how effective these would be.
"At a time and at the place where our headquarters deem necessary, it will take place", he said.
Pence told business leaders before leaving Seoul that the Trump administration is reviewing all trade agreements as part of its "America First" policy.
Recently, Pyongyang has been alarmed by the USA deployment of the THAAD missile system in South Korea in early March.
What does North Korea say?

In Moscow, Russian Foreign Minister Sergey Lavrov told reporters he hopes "there will be no unilateral actions like those we saw recently in Syria and that the USA will follow the line that President Trump repeatedly voiced during the election campaign".
A fresh U.S. warning by Vice President Mike Pence has come with references to United States actions in Syria and Afghanistan and could, therefore, mean that Washington may not shy away from taking a similar action against North Korea.
The North casts the USA as the aggressor. During the recent military parade in Kim Il Sung Square in Pyongyang, North Korea rolled out new missiles on Chinese trucks.
"We know the situation is tense", Wang said.
And what about other world powers?
China has reiterated its call for North Korea to stop all tests, and has also called for a peaceful solution.
Lu stressed that given the complicated and sensitive situation on the Korean Peninsula, China firmly opposes any words and deeds that could heighten hostility and tension and called on all parties involved to make efforts to ease the tension.
Susan Thornton, acting U.S. assistant secretary of state for East Asia, said Secretary of State Rex Tillerson and China's top diplomat, State Councillor Yang Jiechi, agreed in a phone call on Sunday on the need for strict enforcement of United Nations resolutions and for worldwide action to press Pyongyang "to cease provocative actions and recommit to peaceful denuclearisation".
Lavrov warned that "if the United States vice president meant that Washington could unilaterally use military force, then it is a risky road".
