* KCNA says talks would go wrong again if Pompeo stays
* Test of tactical guided weapon staged on Wednesday: KCNA
* First weapons test since failure of Kim-Trump Hanoi summit
* Likely a test of a short-range cruise missile or precision-guided weapon: analysts
North Korea said on Thursday it no longer wanted to deal with US Secretary of State Mike Pompeo and said he should be replaced in talks by someone more mature, hours after it announced its first weapons test since nuclear talks broke down.
The North's official KCNA news agency quoted senior foreign ministry official Kwon Jong Gun as warning that no one could predict the situation on the Korean peninsula if the United States did not abandon the ‘root cause’ that compelled North Korea to develop nuclear weapons.
The statement came shortly after North Korea announced that leader Kim Jong Un had overseen the testing of a new tactical guided weapon, which KCNA said has a ‘peculiar mode of guiding flight’ and ‘a powerful warhead.’
It was the North's first weapon test since talks in Vietnam between Kim and US President Donald Trump in late February broke down over conflicting demands by North Korea for sanctions relief and by the United States for North Korea to abandon its nuclear program.
KCNA gave no details on the weapon that was tested on Wednesday but ‘tactical’ implied a short-range weapon rather than the long-range ballistic missiles that have been seen as a threat to the United States.
KCNA quoted Kwon, who is in charge of US affairs, as saying the Vietnam summit, the second between the two leaders, showed that talks could go wrong ‘whenever Pompeo pokes his nose in.’
‘I am afraid that, if Pompeo engages in the talks again, the table will be lousy once again and the talks will become entangled,’ Kwon said.
‘Therefore, even in the case of possible resumption of the dialogue with the United States, I wish our dialogue counterpart would be not Pompeo but other person who is more careful and mature in communicating with us.’
A spokeswoman for the State Department said it was aware of the report about Pompeo and added: ‘The United States remains ready to engage North Korea in a constructive negotiation.’
Kwon did not elaborate on why North Korea felt compelled to develop nuclear weapons, but North Korea has long spoken of the need to defend itself from what it sees as US aggression.
Kim said last week said the breakdown in talks risked reviving tensions and he gave a year-end deadline for the United States to change its attitude.
Despite the failure of the Vietnam summit, Trump has stressed his good relationship with Kim.
Kwon also said the two leaders were on good terms, even as he castigated Pompeo for ‘fabricated’ stories as part of a ‘publicity stunt.’ He did not elaborate.
Kwon said Pompeo had made ‘reckless remarks hurting the dignity of our supreme leadership,’ apparently referring to him agreeing to the characterisation of Kim as a ‘tyrant’ at a US congressional hearing last week.
'USEFUL REMINDER'
Earlier, Kim Dong-yub, a military expert at Kyungnam University's Institute of Far Eastern Studies in Seoul, said the newly tested weapon was likely a short-range cruise missile that could be launched from the ground, sea and air.
Kim oversaw the test of an unidentified tactical weapon in November.
Experts said in November Kim wanted to shift the mainstay of the North's conventional military power from a nearly 1.3 million-strong army to high-tech weapons.
The young leader said last April that he would stop nuclear tests and launches of intercontinental ballistic missiles because the nuclear capabilities of North Korea, which has tested nuclear devices six times, had been verified.
‘This does serve as a useful reminder of one critical fact: Chairman Kim Jong Un never promised to stop testing all weapons in his military arsenal, just nuclear weapons and ICBMs that have the potential to hit the US homeland,’ said Harry Kazianis of the Washington-based Center for the National Interest.
A US official said that, according initial information, US forces did not detect a missile launch from North Korea. Checks were underway, said the official.
Referring to the test, a White House official said: ‘We are aware of the report and have no further comment.’
South Korea's presidential Blue House declined to comment on the test, referring questions to the defense ministry. It said it was analysing the nature of the weapon and North Korea's intentions.
Kim's visit to the testing site came after he visited the North Korean Air and Anti-aircraft Force on Tuesday, according to KCNA.
Kyungnam University's Kim Dong-yub said the latest test appeared to partly be a message to the United States that North Korea would not bow to sanctions.
‘It's also an internal message to the North Korean people and to the military’ to instill trust in their own security by reinforcing conventional weapons, he said.
Satellite images from last week showed movement at Yongbyon, North Korea's main nuclear site, that could be associated with the reprocessing of radioactive material into bomb fuel, the Center for Strategic and International Studies in the United States said on Tuesday.
US national security adviser John Bolton said in a Bloomberg News interview on Wednesday the United States needed to see ‘a real indication from North Korea that they've made the strategic decision to give up nuclear weapons’ before a third summit between Trump and Kim.
