Iran warned North Korean leader Kim Jong Un not to trust U.S. President Donald Trump who, it said, could cancel their denuclearization agreement within hours.

South Korea's President Moon Jae-in vowed on Tuesday to write "new history" with North Korea, praising North Korean leader Kim Jong Un's decision to hold a summit with the United States in Singapore.

The talks happened as efforts continue to get Donald Trump's summit with Kim Jong-un back on track.

“A small boat was spotted in waters off the north of Baengnyeong Island” near the inter-Korean border, the source told Yonhap news agency, adding that the officer, who holds the rank of major, and a civilian were aboard the vessel. “They expressed willingness to defect,” he said.

North Korea has been seeking a one-on-one meeting between its supreme leader and the U.S. president for more than two decades. And it isn’t difficult to understand why: For the leader of the world’s most powerful country to sit down with his North Korean counterpart would be to bestow an aura of legitimacy and international importance on the rogue state’s regime.

A US B-52 strategic bomber may not take part in ongoing South Korean-US military air drills according to a source, after North Korea cancelled bi-lateral talks with South Korea and threatened to cancel its upcoming summit with Donald Trump in June. The Thunder military exercise began on Friday and is scheduled to continue for two weeks. It will include around 100 aircraft, including F-15Ks, F-16s, and F-22 radar-evading fighter jets.

South and North Korea reportedly plan to conduct high-level talks this week as the estranged nations work towards a peace deal, the South Korean Unification Ministry said. The two nations agreed to again have officials meet at the so-called neutral "truce village” of Panmunjom, which straddles their border. 

With North Korea pledging to reduce tensions and renew ties with its southern neighbor, South Korea’s hottest property market is now along the heavily fortified border between the two countries. Demand for property in small towns and sparsely populated rural areas around the Demilitarised Zone (DMZ) is surging on expectations of an influx of people and investment.

President Trump has ordered the Pentagon to prepare options for drawing down American troops in South Korea, just weeks before he holds a landmark meeting with North Korea’s leader, Kim Jong-un, according to several people briefed on the deliberations. Reduced troop levels are not intended to be a bargaining chip in Mr. Trump’s talks with Mr. Kim about his weapons program, these officials said. But they acknowledged that a peace treaty between the two Koreas could diminish the need for the 28,500 soldiers currently stationed on the peninsula.

North Korea will shift its time zone 30 minutes earlier to align with South Korea starting May 5 "as a first practical step for national reconciliation and unity," the North's state media said Monday. North Korean leader Kim Jong Un said it was "a painful wrench" to see two clocks showing different Pyongyang and Seoul times on a wall at the summit venue during the historic meeting Friday with President Moon Jae-in, KCNA said. Meanwhile, China will send the government's top diplomat, Wang Yi, to visit North Korea on Wednesday and Thursday this week, the foreign ministry said on Monday.

North Korean leader Kim Jong Un reportedly said he would give up his nation's nuclear weapons if the United States vows not to invade his country. The New York Times reported remarks from a South Korean official, who recounted Kim’s remarks in the historic meeting between Kim and South Korean President Moon Jae-In.

North Korean leader Kim Jong-un has vowed to shut down the country's nuclear test site in May and open the process to experts and journalists from South Korea and the United States, Seoul's presidential office said Sunday. Kim made the comments during his summit with South Korean President Moon Jae-in on Friday at a border truce village, where he also expressed optimism about his anticipated meeting with Donald Trump, saying the U.S. president will learn he's "not a person" to fire missiles toward the United States, Moon's spokesperson Yoon Young-chan said.

The Korean War will be formally declared over after 68 years, the North and South have said. At a historic summit between leaders Kim Jong-un and Moon Jae-in, the neighbouring countries agreed they would work towards peace on the peninsula with a formal end to the conflict set to be announced later this year.

South Korea’s foreign minister has said she believes President Donald Trump is largely responsible for bringing North Korean leader Kim Jong-un to the negotiating table.

KIM Jong-un has stepped across the border with South Korea for historic talks with President Moon Jae-in. The meeting marks the first time one of the ruling Kim leaders has crossed over to the southern side of the Demilitarised Zone since fighting in the Korean War stopped in 1953.

With a single step over a weathered, cracked slab of concrete, North Korean leader Kim Jong Un made history Friday by crossing over the world’s most heavily armed border to greet South Korean President Moon Jae-in for talks on North Korea’s nuclear weapons. Kim then invited Moon to cross briefly back into the north with him before they returned to the southern side.

A meeting between Mr. Kim, North Korea’s leader, and President Moon Jae-in of South Korea seemed unthinkable just a few months ago.

North Korean leader Kim Jong Un and South Korean President Moon-Jae-in will plant a commemorative tree and inspect an honor guard together after Kim walks across the border Friday for their historic summit, Seoul officials said Thursday. The talks on the southern side of the border village of Panmunjom are expected to focus on North Korea's nuclear program, but there will be plenty of symbolism when Kim becomes the first North Korean leader to be in the southern section of the border since the end of the 1950-53 Korean War.

South Korea turned off loudspeakers blaring bouncy music and other propaganda into North Korea on Monday, silencing weapons of psychological warfare so annoying to the North that its military once fired shots across the border. The South’s Defense Ministry said it switched off all batteries of the propaganda loudspeakers along the inter-Korean border, known as the Demilitarized Zone, days before its president, Moon Jae-in, is to join the North’s leader, Kim Jong-un, there on Friday for a summit meeting.

North Korean leader Kim Jong Un's promise to build "socialist economic construction" in his nuclear-armed but impoverished and isolated country could herald more Chinese-style economic reforms, according to analysts — but he will never explicitly say so. Alongside the declaration on Saturday that the North had completed the development of its nuclear arsenal and no more atomic or missile tests were needed, Kim proclaimed that the "new strategic line" for the ruling Workers' Party would be "socialist economic construction".
