North Korea’s defence minister No Kwang Chol threatened on Saturday to take “more offensive action” as he condemned US security talks with Seoul and the arrival of a US aircraft carrier in South Korea.

A day earlier, North Korea fired a ballistic missile towards the sea off its east coast, after denouncing on Thursday fresh US sanctions against North Korean individuals and entities that Washington said were involved in cyber-related money-laundering schemes.

South Korea’s defence ministry on Saturday condemned the missile launch, while saying the North’s criticism of the US-South Korea meeting was regrettable.

No criticised a recent visit by US and South Korean defence chiefs to the border between North and South Korea, as well as their subsequent security talks in Seoul, alleging they were conspiring to step up deterrence efforts towards the North and to integrate their nuclear and conventional forces.

“This is a stark revelation and an unveiled intentional expression of their hostile nature to stand against the DPRK to the end,” No said, referring to the country’s formal name - the Democratic People’s Republic of Korea.

US Defense Secretary Pete Hegseth said on Tuesday the core of the alliance with Seoul will remain focused on deterring North Korea, although Washington will look at flexibility for US troops stationed in South Korea to operate against regional threats.

No also said the visit of the US nuclear-powered aircraft carrier George Washington to South Korea’s southeastern port city of Busan this week following US-South Korean joint air drills with Seoul had escalated tensions on the peninsula.

“We will show more offensive action against the enemies’ threat on the principle of ensuring security and defending peace by dint of powerful strength,” No said, according to North Korean state media KCNA.

South Korea’s navy said the carrier’s visit was to replenish supplies and grant leave for the crew.

While visiting South Korea last week, US President Donald Trump repeated his willingness to sit down with North Korean leader Kim Jong Un. No meeting took place, but Trump said he was willing to return to the region to meet Kim.

Last week, North Korea also test-fired cruise missiles to the west of the Korean peninsula just as Trump and other leaders were set to gather in South Korea for regional meetings.

Regarding the latest missile launch, the US Indo-Pacific Command said on Saturday that it “does not pose an immediate threat to US personnel or territory, or to our allies”.

“The missile launch highlights the destabilising impact” of North Korea’s actions, it added.
