North Korea seems "sincere" in its apparent willingness to halt nuclear tests if it holds denuclearisation talks with the United States, Trump said on Tuesday, as US, South Korean and Japanese officials voiced scepticism.
South Korea's President Moon Jae-in said on Wednesday sanctions on North Korea will not be eased for the sake of a summit with Pyongyang, but China's state media warned nuclear North Korea will not be intimidated and that talks were the only solution.
"We believe it is a good thing, and look forward to a positive outcome of the meeting", foreign ministry spokesman Geng Shuang said at a regularly scheduled news conference Monday.
North Korean leader Kim Jong-un agreeing to hold the inter-Korean summit in the South Korean side of the border hints at Kim's personality, and Pyongyang's desire to be seen as a "normal country", experts say. It is the only country to have tested nuclear weapons this century and remains the greatest and most immediate threat in the Indo-Asia-Pacific area.
President Trump welcomed the change in tone, but reiterated that he is still ready to "go either way" when it comes to his response.
"The reality is that North Korea now has an intercontinental ballistic missile that can allegedly hit targets in the US", the paper wrote.
Meanwhile, we must urge Congress to pass legislation, sponsored by Senator Chris Murphy and Representative Ro Khanna, barring the president from attacking North Korea without congressional authorization.
The additional sanctions on Pyongyang went into effect on March 5 after the finding was formally published in the Federal Register, the official journal of the US Government, Ms Nauert said.
On Tuesday, Washington announced it had formally concluded that VX - an extremely powerful nerve agent - was used to conduct the slaying and that North Korea was to blame. But everything hinges on the attitude of the US.
Mr Trump said the recent rhetoric coming out of North and South Korea was "very positive" in the wake of the two nations' rare meeting.
Given past bloodshed, North Korean weapons tests and threats of war, there's considerable skepticism over what might come of the Koreas' warming ties.
North Korea's attitude is that this should be on the basis of mutual respect and the norm of the give and take of the negotiations.
Kim has made atomic weapons a core part of North Korea's political identity.
The North Korean regime has also sought to separate the South from the United States and Japan, and some government figures also fear that the talks are designed to shift the diplomatic landscape under Pyongyang's own timing.
But the North's state media made no mention of the developments, with the Rodong Sinmun, the mouthpiece of the ruling Workers Party, instead leading on messages of congratulation sent to Kim for the 70th anniversary last month of the founding of the North's military.
It also further emphasized why North Korea's nuclear weapons program was "justifiable" and not to be disputed by the West or any other international powers. They resulted in a series of cooperative projects between the Koreas that were scuttled during subsequent conservative administrations in the South.
South Korean officials who met the North Korean leader will leave for Washington on Thursday.
Tensions have been high between Washington and Pyongyang over North Korea's missile and nuclear programs.
