Mr Trump says he is not ruling out military action against North Korea but has also expressed openness to a future meeting with its ruler Kim Jong Un, offering unusual praise for the third-generation dictator amid the nuclear tensions. He revived it in an interview Monday with Bloomberg News, saying, "If it would be appropriate for me to meet with him, I would absolutely; I would be honoured to do it". "But I would do that".
Pyongyang's latest attempted show of force was a failed missile test on Saturday that came just hours after US Secretary of State Rex Tillerson pressed the UN Security Council to raise pressure on the North.
The President has refused to rule out a pre-emptive strike, but has also been trying to get China to convince the North Korean leader to stop the tests.
Mr Trump first broached the idea of sitting down with Mr Kim during the 2016 presidential campaign.
North Korea, which usually makes public statements through its state-run Korean Central News Agency and the Rodong Sinmun, has yet to respond to the remarks.
"Clearly conditions are not there right now", he added.
"I give him great credit for being able to turn that around", he said.
"There is nothing right now facing this country and facing the region that is a bigger threat than what is happening in North Korea", the White House chief of staff said.
"The United States of America will always seek peace but under President Trump, the shield stands guard and the sword stands ready", Pence added.
"While forcing South Korea to pay $1 billion for the cost of THAAD and for protection, one can see he is nothing but a vicious hooligan, a scam artist", the publication from North Korea's de facto embassy in Japan stated.
Kim's predecessors weren't much more accessible or cooperative.
The six-party talks have been stalled ever since. The nation's capital is home to its nuclear program, and Trump immediately called out North Korea for acting against China's wishes.
It says that unless Washington ends its "hostile policy" and nuclear threats, North Korea "will continue to bolster its military capabilities for self-defense and pre-emptive nuclear attack" despite "manifold difficulties".
Tensions have escalated since Mr Trump vowed in January that he wouldn't let North Korea develop a nuclear weapon capable of reaching the United States, and North Korea has labelled American military moves in the region as acts of "intimidation and blackmail".
The two supersonic B-1B Lancer bombers were deployed amid rising tensions over North Korea's dogged pursuit of its nuclear and missile programmes in defiance of United Nations sanctions and pressure from the United States.
President Putin's Russian Federation also said the global community should not take "provocative" action. Mr Trump and Mr Xi met last month at the United States president's private club in Florida and have talked several times since.
His administration has said since that North Korea must agree to abandon its nuclear program. At the time, she was the most senior official to visit years since the Korean War.
