Kim Jong Un warns North Korea could consider change of tack

North Korea's leader Kim Jong Un has said he is ready to meet with US President Donald Trump again at any time AFP/SAUL LOEB

"If the US does not keep its promise made in front of the whole world ... and insists on sanctions and pressures on our republic," Kim said, "we may be left with no choice but to consider a new way to safeguard our sovereignty and interests".

Kim was referring to his summit with US President Donald Trump in Singapore in June, when he said he had "fruitful talks" and "exchanged constructive ideas".

At the time the two leaders signed a vaguely-worded pledge on denuclearisation of the Korean peninsula, but progress has since stalled with Pyongyang and Washington arguing over what that means.

The North is subject to multiple sets of United Nations Security Council sanctions over banned nuclear and ballistic missile weapons programmes, which have seen it carry out six atomic tests and launch rockets capable of reaching the entire US mainland.

"I am ready to sit with the US President again at any time in the future and will make efforts by all means to produce a result that will be welcomed by the international community," Kim said in his address, broadcast by the North's state television.

Kim spoke sitting in a dark leather armchair, in a large office flanked with packed bookshelves along one side and paintings of his predecessors, his father Kim Jong Il and grandfather Kim Il Sung behind him.

As he began speaking - in a deep, gravelly voice - a clock behind him showed the time as just moments after 12.

But at times during the address it was blurred out, and towards the end of the half-hour broadcast it was close to 1, suggesting the speech was recorded in several takes.

YEAR OF RAPPROCHEMENT

The leader's New Year speech is a key moment in the North Korean political calendar, reviewing the past and setting out out goals for the future.

The 2018 address was a crucial catalyst for the developments that followed.

It came after a year of high tensions when the North made rapid progress in its weapons programmes and fears of conflict rose.

The two leaders traded personal insults - Trump mocked Kim as "Little Rocket Man", who in turn called him a "mentally deranged US dotard" - and threats of war.

On January 1 2018 Kim ordered mass production of missiles and bombs and warned the whole US mainland was "within the range of our nuclear strike and the nuclear button is on my office desk all the time".

But he also offered to send a team to the forthcoming Winter Olympics in the South - opening the way for the South's dovish President Moon Jae-In to play the role of peace broker.

A rapid sequence of developments followed, with athletes and a senior delegation led by his powerful sister going to the Pyeongchang Games in February, before Kim met Chinese President Xi Jinping in Beijing ahead of the Singapore summit with Trump.

Kim also met with Moon three times last year - twice at the border truce village of Panmunjom and once in the North's capital Pyongyang - and at the weekend vowed to meet Moon "frequently" this year.

In his speech Tuesday Kim said the US and South Korea should no longer carry out joint military exercises - which have been largely halted since the Singapore meeting - calling such drills "a source of tension".

"War-related equipment - including strategic assets of outside powers - should no longer be allowed to be brought in," he added.

Seoul and Washington are in a security alliance and the US stations 28,500 troops in the South to protect it against its neighbour, which invaded in 1950.
