Kim's fourth visit to China comes ahead of a much-anticipated summit with USA president Trump later this year.
North Korean leader Kim Jong Un has reportedly told the leader of his only major ally, China, that he wants to "achieve results" on the nuclear standoff on the Korean Peninsula during a second summit with U.S. President Donald Trump.
"The second North Korea-U.S. summit, soon to take place, and a reciprocal visit to Seoul by Chairman Kim Jong-un could be turning points in securing peace on the Korean Peninsula".
"Ultimately, resolving the issue of North Korean sanctions is dependent on the speed of denuclearization, so North Korea needs to take bolder practical denuclearization steps", Moon said regarding the deadlock in US-North Korea negotiations. On Monday, Kim made his fourth trip to China, where he met with Chinese President Xi Jinping and inspected industrial facilities.
Discussions between the U.S. and North Korea over Pyongyang's nuclear arsenal have stalled since Kim and Trump's high-profile summit in Singapore in June where they issued a vaguely worded declaration about denuclearisation.
"Corresponding measures must be devised in order to facilitate North Korea's continued denuclearization efforts", he added, such as the United States agreeing a "peace regime" and formally declaring an end to the 1950-53 Korean War.
Kim held three summits a year ago with Xi, his most important ally, before and after summits with Trump and South Korean President Moon Jae-in.
"But Hawaii is said to be an unrealistic location, as it doesn't have a North Korean embassy there", another official added. -North Korea summits and hopes the two sides "will meet each other halfway".
North Korea wants relief from the multiple sets of sanctions imposed on it over its nuclear weapon and ballistic missile programs, while the United States wants them to remain in place until it gives up its arms - something Pyongyang has made no public promise to do.

However China's state-run Global Times newspaper appeared to reveal the birth year of the North Korean leader in a tweet. Kazianis, Director of Defence Studies at the US -based Centre for the National Interest, said in an e-mailed statement.
Kim also said North Korea hopes its "legitimate concerns" would be given due respect, a reference to Pyongyang's desire for security guarantees and a possible peace treaty to formally end the 1950-53 Korean War.
But many analysts say that restarting the schemes would at present violate sanctions imposed on the North over its nuclear and ballistic missile programs.
Kim spent around half an hour touring a pharmaceutical factory operated by Tong Ren Tang, the largest producer of traditional Chinese medicinal products. Those projects include a jointly-run factory complex in North Korea, and the opening of new tourist areas.
Xi greeted Kim at Beijing's ornate Great Hall of the People on Tuesday - believed to be the North Korean leader's birthday.
Mr Moon said Mr Kim's latest trip to Beijing signalled that a second summit was imminent. Mr. Kim was accompanied by his wife, Ri Sol Ju, the news agency said.
Details of what Kim and Xi discussed have yet to be revealed, but their summit is seen as an opportunity to strategize ahead of a second North Korea-U.S. summit meant to move along denuclearization negotiations.
"China has been an important force in promoting the political settlement of the Korean Peninsula nuclear issue and peace and stability on the peninsula", said Lu.
Some analysts say China could use its cooperation on the North Korean issue as a bargaining chip in the United States trade talks.
