TEHRAN, Young Journalists Club (YJC) - Putin said that he will be willing to share details of the summit with U.S. President Donald Trump, adding that "there are no secrets."
He noted that Kim himself encouraged him to explain certain nuances of Pyongyang's position to Trump.
The summit on Russky Island, across a bridge from the far-eastern port city of Vladivostok, reflected Russia's effort to emerge as an essential player in the North Korean nuclear standoff, a role that would raise Moscow's global clout and its leverage with Washington.
Putin emphasized that the North Korean leader is ready to move toward a nuclear-free status but would only proceed when he gets solid guarantees.
He did not, however, specify what those guarantees would look like. "Above all, he focuses on protecting national interests and security," Putin said.
Earlier in the day, Putin voiced confidence that Kim's visit will "help better understand what should be done to settle the situation on the Korean Peninsula, what we can do together, what Russia can do to support the positive processes going on now."
Kim's meeting with Putin follows a year of intense diplomacy the North hopes will help it get out from under international sanctions over its nuclear weapons and long-range missile programs.
Kim has already held four summits with Chinese President Xi Jinping, three with South Korean President Moon Jae-on and two with President Donald Trump.
Kim's second summit with Trump in February ended without any agreements, and his trip to Russia reflects his desire to put more pressure on Washington and show some independence from Beijing as well.
For Putin, the meeting offers a chance to increase his role as a potential broker.
He immediately emphasized that he was willing to share details of the talks with Trump.
The Russian leader emphasized that Moscow and Washington both want Pyongyang to denuclearize. When he sat down for talks with Kim, he praised him for engaging in dialogue with the U.S.
"We welcome your efforts to develop an inter-Korean dialogue and normalize North Korea's relations with the United States," Putin told Kim.
Following their one-on-one meeting at the start of broader talks involving officials from both sides, Putin and Kim said they had a good discussion.
"We discussed the situation on the Korean Peninsula and exchanged opinions about what should be done to improve the situation and how to do it," Putin said. Kim described the talks as "candid and meaningful."
"The reason we visited Russia this time is to meet and share opinions with your excellency, President Putin, and also share views on the Korean Peninsula and regional political situation, which has garnered the urgent attention of the world, and also hold deep discussions on strategic ways to pursue stability in the regional political situation and on the matters of jointly managing the situation," Kim said.
