SEOUL: The leaders of North and South Korea embraced on Friday after pledging to work for the "complete denuclearisation of the Korean peninsula", on a day of smiles and handshakes at the first inter-Korean summit in more than a decade.
The two Koreas announced they would work with the United States and China this year to declare an official end to the 1950s Korean War and seek an agreement to establish "permanent" and "solid" peace.
The declaration included promises to pursue phased arms reduction, cease hostile acts, transform their fortified border into a peace zone and seek multilateral talks with other countries including the United States.
"The two leaders declare before our people of 80 million and the entire world there will be no more war on the Korean peninsula and a new age of peace has begun," the two sides.
South Korean President Moon Jae-in agreed to visit the North Korean capital of Pyongyang this year, they said.
Earlier, North Korea`s Kim Jong Un became the first North Korean leader since the 1950-53 Korean War to set foot in South Korea after shaking hands with his counterpart over a concrete curb marking the border in the heavily fortified demilitarised zone.
Scenes of Moon and Kim joking and walking together marked a striking contrast to last year`s barrage of North Korean missile tests and its largest ever nuclear test that led to sweeping international sanctions and fears of war.
Their meeting comes weeks before Kim is due to meet US President Donald Trump in what would be the first ever meeting between sitting leaders of the two countries.
Trump welcomed the Korean talks.
"After a furious year of missile launches and Nuclear testing, a historic meeting between North and South Korea is now taking place. Good things are happening, but only time will tell!" he said on Twitter.
He later added: "KOREAN WAR TO END! The United States, and all of its GREAT people, should be very proud of what is now taking place in Korea!"
China welcomed the leaders' statement and said it was willing to keep playing a proactive role in promoting political solutions on the peninsula.
Japanese Prime Minister Shinzo Abe also welcomed the summit and said he expected North Korea to take concrete steps to carry out its promises.
Global markets were lifted by hopes the summit would pave the way for the end of conflict on the Korean peninsula. Shares in Seoul briefly rose more than 1 percent to a one-month high and Japan`s Nikkei share average also gained.
`BALL IN US COURT`
As part of efforts to reduce tension, the two sides agreed to open a liaison office, stop propaganda broadcasts and leaflet drops along the border and allow Korean families divided by the border to meet.
Days before the summit, Kim said North Korea would suspend nuclear and long-range missile tests and dismantle its only known nuclear test site.
But there has been widespread scepticism about whether Kim is ready to abandon the nuclear arsenal his country has developed for decades, justifying it as a necessary deterrent against US invasion.
"Everything will not be resolved in the blink of an eye," said Kim Young-hee, a North Korean defector-turned-economist at the Korea Development Bank.
"Kim Jong Un has put the ball in the US court. He declared denuclearistion, and promised to halt nuclear tests," she said. "That tells us he wants the United States to guarantee the safety of his regime ... in return for denuclearisation."
It is not the first time leaders of North and South Korea have declared hopes for peace. Two earlier summits, in Pyongyang in 2000 and 2007, failed to halt the North`s weapons programmes or improve relations in a lasting way.
"We will make efforts to create good results by communicating closely, in order to make sure our agreement signed today before the entire world, will not end as just a beginning like previous agreements before today," Kim said after the agreement was signed.
FIRST ACROSS THE LINE
Earlier, Moon greeted Kim at the military demarcation line where the men smiled and shook hands.
In an unplanned move, Kim invited Moon to step briefly across into North Korea, before the two leaders crossed back into South Korea holding hands.
"I was excited to meet at this historic place and it is really moving that you came all the way to the demarcation line to greet me in person," Kim said, wearing his customary black Mao suit.
"A new history starts now. An age of peace, from the starting point of history," Kim wrote in Korean in a guest book in the South's Peace House before talks began.
During a private meeting in the morning, Kim told Moon he came to the summit to end the history of conflict and joked he was sorry for waking Moon up with his early morning missile tests, a senior presidential official said.
Moon and Kim released their joint declaration before attending a dinner banquet.
The United States was hopeful talks would make progress on achieving peace and prosperity, the White House said in a statement as the two men began their summit.
The White House also said it looked forward to continuing discussions with South Korea in preparation for the planned meeting of Trump and Kim in coming weeks.
Just months ago, Trump and Kim were trading threats and insults as the North made rapid advances in pursuit of nuclear-armed missiles capable of hitting the United States.
The United States stations 28,500 troops in South Korea as a legacy of the Korean War, which ended in a truce, not a peace treaty. The war pitted the South, UN and US forces against the communist North, backed by China and Russia.
Kim and Trump are expected to meet in late May or June. Trump said on Thursday he was considering several dates and venues.
