WASHINGTON, March 19 (Yonhap) -- U.S. National Security Adviser John Bolton said Tuesday that a new missile or nuclear test by North Korea would have a "real impact" on President Donald Trump.
There is speculation Pyongyang could be preparing another missile launch following the collapse of last month's summit between Trump and North Korean leader Kim Jong-un.
A top North Korean official added to the concern last week, saying Kim will decide soon whether to maintain his moratorium on nuclear and missile tests.
"Well, the president himself said he would be very, very disappointed -- his phrase -- if North Korea were to resume missile testing or nuclear testing," Bolton said on Fox Business.
"This was a commitment that Kim Jong-un has made several times to him now. So, if in fact they decided to start testing again, it would have a real impact on the president," he said.
Trump has repeatedly cited the North's suspension of testing as an achievement of his diplomatic engagement with Kim.
Their second summit in Hanoi, Vietnam, ended without a deal due to disagreements over the extent of North Korea's denuclearization and sanctions relief from the U.S.
"Look, the president's given them a real opportunity for a bright economic future if they get rid of their weapons of mass destruction and ballistic missile programs," Bolton said. "I'd like to say he's holding the door open to him to a very bright economic future. It's really just up to the North Koreans to walk through."
Bolton has long held hawkish views of Pyongyang.
And in her remarks last week, North Korean Vice Foreign Minister Choe Son-hui accused him and Secretary of State Mike Pompeo of creating an atmosphere of hostility and mistrust at the summit.
Both men denied the charge.
North Korea's last nuclear or missile test occurred in November 2017 when the regime launched an intercontinental ballistic missile apparently capable of reaching the U.S.
