Trump warns Kim has 'everything' to lose through hostility

President Donald Trump warned Sunday that North Korea's Kim Jong Un had "everything" to lose through hostility towards the United States, after Pyongyang said it had carried out a major new weapons test.

"Kim Jong Un is too smart and has far too much to lose, everything actually, if he acts in a hostile way," Trump tweeted in response to the unspecified test at the Sohae space launch center.

The announcement of Saturday's test came just hours after Trump said he would be "surprised" by any hostile action from the North, emphasizing his "very good relationship" with Kim.

Trump and Kim engaged in months of mutual insults and threats of devastation in 2017, sending tensions soaring before a diplomatic rapprochement the following year.

The pair have met three times since June 2018 but with little progress towards denuclearisation.

Pyongyang has set Washington a December 31 deadline to make new concessions to kickstart stalled talks.

"North Korea, under the leadership of Kim Jong Un, has tremendous economic potential, but it must denuclearise as promised," Trump tweeted.

"NATO, China, Russia, Japan, and the entire world is unified on this issue!" Writing that Kim had "signed a strong Denuclearisation Agreement" at their June 2018 summit in Singapore," Trump warned: "He does not want to void his special relationship with the President of the United States or interfere with the US Presidential Election in November."
A senior US administration official earlier said Washington had seen reports of a test and was "coordinating closely with allies and partners."
North Korea fired back that if the United States used military force it would take "prompt corresponding actions at any level."
