Kim Jong-un has expressed ‘great satisfaction’ after receiving another ‘good personal letter’ from President Donald Trump ahead of their second summit.

The North Korean leader is said to be making ‘good technical preparations’ for the meeting scheduled in February, Pyongyang’s state media reported.

A number of letters have been exchanged between the pair since their historic meeting in Singapore last June.

The latest note was hand-delivered to Kim by North Korea’s top nuclear negotiator and former spy chief Kim Yong Chol, who met with Trump and Secretary of State Mike Pompeo last week.

‘[Kim] spoke highly of President Trump for expressing his unusual determination and will for the settlement of the issue with a great interest in the second DPRK-US summit,’ the Korean Central News Agency, the country's state media, said.

Kim continued that North Korea would ‘believe in the positive way of thinking of President Trump (and) wait with patience and in good faith,’ the agency added.

Trump previously said of the letters that they had resulted in the pair falling ‘in love’.

Speaking at a political rally in West Virginia in September, the President said: ‘He wrote me beautiful letters and they’re great letters. We fell in love.’

Nuclear negotiations have been stuck since Kim and Trump met in Singapore last June for their first summit, which ended with Kim's vague denuclearization pledge that his government had previously used when it called for the withdrawal of the 28,500 U.S. troops in South Korea.

A summit accord also stated that the United States and North Korea will commit to establishing new relations and join efforts to build a lasting and stable peace on the Korean Peninsula.

North Korea observers say Vietnam is likely to be chosen as a venue for a second summit but there has been no official confirmation.

Kim has also ordered staff to start ‘good technical preparations’ for the second summit scheduled in February, Pyongyang’s state media reported

The White House made the announcement on Friday, as Press Secretary Sarah Sanders said: 'President Donald J. Trump met with Kim Yong Chol for an hour and half, to discuss denuclearization and a second summit, which will take place near the end of February.

'The President looks forward to meeting with Chairman Kim at a place to be announced at a later date.'

North Korea recently warned the Trump administration that it could restart nuclear and missile tests if the United States sticks with its 'one-sided demands.'

The nation's 35-year-old dictator suggested that he could lean on Beijing harder.

He said in a New Year's day address that he would have 'no choice but to defend our country’s sovereignty and supreme interest, and find a new way to settle peace on our peninsula' without additional action from the United States.

That same week, Trump cryptically left a poster on the table at a Cabinet meeting that cautioned 'sanctions are coming' that was not addressed to any country in particular.

Several days later the president told reporters as he left for Camp David that he'd be discussing the North Korean nuclear threat with his team over the weekend.

'North Korea, we're doing very well. And again, no rockets. There's no rockets. There's no anything. We're doing very well,' he said.

'I've indirectly spoken to Chairman Kim. And when I came here, this country was headed to war with North Korea. And now we have a very good dialogue going.'
