The tubby despot said his communist state is “fully prepared for confrontation” after it snubbed recent efforts by the new US administration to establish diplomatic communications. His outburst marks the first direct message from the repressive nation to the new US President.
A slimmed-down Mr Kim vowed that his country was “fully prepared for confrontation in order to protect the dignity of our state and its interests for independent development”, according to state media outlet KCNA.
He said this was essential to guarantee a peaceful environment and North Korea’s security during a meeting of the country’s senior leaders which began this weekend.
He also warned that North Korea would “sharply and promptly” react to any developments and “concentrate efforts on taking stable control of the situation on the Korean peninsula”.
And while vocally boasting that he was ready for war, he also said that the country was prepared for “dialogue”.
It has long struggled to feed its people – with a famine in the 1990s thought to have killed up to 3.5 million people.
And with the two leaders’ relationship being fraught with tension – these sanctions seem unlikely to be lifted anytime soon.
Mr Biden has previously called Mr Kim a “thug” and said he was a “serious threat” to global security.
North Korea reacted furiously, showcasing a new missile during a huge military parade days before Mr Biden’s inauguration in January.
It also claimed that his comments reflected Mr Biden’s intent to “keep enforcing the hostile policy” towards the country.
Their relationship is a far cry from the one enjoyed by Mr Biden’s predecessor Donald Trump.
After exchanging personal insults, the two men held face-to-face talks which observers hoped would bring North Korea back into the international fold.
The pair met three times – including a seminal summit in Singapore in June 2018.
Both sides dropped their confrontational tone and signalled that progress could be made.
But talks on denuclearisation eventually stalled – resulting in little real change being achieved.
