"If the USA does not keep its promise made in front of the whole world. and insists on sanctions and pressures on our republic", Kim said on Tuesday, "we may be left with no choice but to consider a new way to safeguard our sovereignty and interests".
Trump and Kim held an historic summit in Singapore in June, at which Kim said he was committed to denuclearising the Korean Peninsula.
"I am ready to sit down again with the US President any time and make efforts towards producing an outcome that would be welcomed by the global community", he said yesterday morning in a televised address. However, he said the North will be forced to take a different path if the United States "continues to break its promises and misjudges our patience by unilaterally demanding certain things and pushes ahead with sanctions and pressure".
North Korea seems determined in 2019 to receive some sort of sanctions relief - or what Kim referred to as "corresponding measures" - as part of any bargain with the Trump Administration."Duyeon Kim, an adjunct senior fellow at the Center for a New American Security: "As expected, he didn't rock the boat, clearly being mindful of the diplomatic process with Washington and didn't brag about his nuclear might".
Kim and Trump met June 12 in Singapore where they signed a vague statement on a nuclear-free Korean Peninsula without describing when and how it would occur.
Kim called for South Korea to "completely stop" joint military drills with the United States involving strategic assets, while multilateral negotiations among countries involved in the armistice agreement should be pursued to build a permanent peace regime.
The address, broadcast at 9 a.m. local time on North Korea's state-run television network, was Kim's seventh since taking power following the death of his father, Kim Jong Il, in 2011.
Although Pyongyang did not conduct nuclear or missile tests a year ago, satellite images have pointed to continued activity at the North's related facilities.
But while Kim Jong Un says he wants to continue along the diplomatic path, the clear hint is that without some response from the United States, the rapprochement witnessed past year may go into reverse.

They pulled within a half-game of the No.5 seed Seattle Seahawks, who were defeated by the San Francisco 49ers in overtime. I know I've talked about it for a long time: "I have goals to not only play next year, but beyond that", Brady said.
Instead, Kim said his patience with the US-led sanctions regime designed as punishment for his nuclear weapons programme was running out.
Neither of those are now possible for South Korea unless sanctions on the North are removed. At the summit, the president hailed a new beginning in U.S.
In the 30-minute speech, Kim spent more than 20 minutes highlighting his campaign to create a "self-reliant" economy despite a "harsh economic blockade". He also suggested reviving the operation of the South Korean industrial park near the North Korean city of Kaesong and the Mount Kumgang tourist resort.
The setting, which mimics the one favored by Chinese President Xi Jinping for his New Year address, marks a departure from previous years when Kim stood before an assembly hall packed with officials.
Kim urged the U.S.to take "sincere measures and corresponding action" in response to North Korea's peace initiatives.
He spoke warmly of his three 2018 meetings with South Korean President Moon Jae-in and of the rapprochement between the two nations, but he said that progress should be consolidated by ending joint military exercises with the United States.
Nuclear talks between Washington and Pyongyang have stalled for months as they struggle with the sequencing of North Korea's disarmament and the removal of USA -led sanctions against the North. There are views that North Korea wants a quick second summit because it thinks it can win major concessions from Trump that they probably couldn't from lower level US officials, who are more adamant about the North committing to inspections and verification.
Mr Kim also met with President 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.
