Yet, by advocating such an idea, China's ultimate aim is to push for the reduction and even the termination of America's military presence in South Korea. That includes sanctions, military exercises, and the stationing of United States forces near its border with South Korea.
Kim Jong Un's predecessors, grandfather Kim Il Sung and father Kim Jong Il, both promised not to pursue nuclear weapons but secretly maintained programmes to develop them, culminating in the North's first nuclear test in 2006 under Kim Jong Il.
"There are no plans to initiate a summit between Russian Federation and North Korea, and there are no plans for President Vladimir Putin and Chairman Kim to meet", the Kremlin stated Wednesday.
China, South Korea, Japan, and Russian Federation all now want closer relations with Pyongyang, because Kim piqued Trump's interest by saying "denuclearization".
But China, a military giant over the border, is still responsible for virtually all of North Korea's food and fuel aid.
Meanwhile, the March 25-28 visit to China by Kim Jong Un and his wife Ri Sol Ju was confirmed by both North Korean and Chinese media early Wednesday. Kim, rumored to have had a fear of flying, traveled to China on a green-and-yellow armored train that was also used by his son this week.
China's participation in the peace talks on the Korean Peninsula has helped stabilize the situation there, South Korea's presidential Blue House said Thursday. According to some experts, the meeting with China proves Kim is open to diplomatic talks as he made his first visit as a state head. The two men had not met since Kim took over after the death of his father, Kim Jong Il, in December 2011, and relations have been strained as China has backed a series of United Nations sanctions against Pyongyang over its nuclear and missile tests. "Look forward to our meeting!".
North Korea's supreme leader Kim Jong Un. China also said it would proceed with a formal action before the WTO against Washington and is prepared financially to face the sequels of the present confrontation. Trump seemed anxious to meet Kim Jong Un for himself.
"It's part of the North's demand for substantial recognition that it exists and it will hold the West, including the United States, to account", said Peter Hayes, director of the Nautilus Institute for Security and Sustainability, a research group that specializes in North Korea. Kim wore horn-rimmed glasses and was shown jotting down notes and speaking in a calm manner.
Japanese Prime Minister Shinzo Abe will be meeting Trump at his Mar-a-Lago estate next month and his top most priority will be to discuss the president's meeting with the North Korean leader, which was reportedly arranged on Abe's instruction after he learned that Trump has accepted Kim's request for a face-to-face meeting.
When Mr Kim sits down with Mr Trump, Mr Xi will not be in the room but his shadow will loom large. In 2003, China launched the Six-Party Talks aimed at peacefully resolving the North Korean nuclear crisis, which eventually failed.
Kim's trip to meet with the country's oldest and only real ally has been shrouded in mystery. According to the official summary of the visit released by Chinese state news agency Xinhua, the North Korean leader asked China to "jointly safeguard the trend of consultation and dialogue as well as peace and stability on the peninsula".
South Korean officials, nonetheless, applauded Kim for "reaffirming his commitment to the denuclearization of the Korean Peninsula", as relayed by other North Korean officials. North Korea's provocations also took a toll on relations with Beijing.
The Trump administration has slapped sanctions on companies across the globe to punish illicit trade with North Korea. China has cooperated in applying sanctions to Kim's regime and would welcome a resumption of full trading relations.
North Korea may also demand that South Korea pay the North money or provide financial incentives, which could violate global sanctions against the North. The Xi-Kim meeting changes that.
"It's most proper that my first overseas trip would be the capital of the People's Republic of China", Kim Jong Un said, according to the North's KCNA.
Throughout it all, China has portrayed itself as the one steering the agenda.
