The men released a statement through the State Department: "We would like to express our deep appreciation to the United States government, President Trump, Secretary Pompeo, and the people of the United States for bringing us home".
Pyongyang had changed a lot in two decades.
South Korean President Moon Jae-in has pushed for Panmunjom, one reason Trump considered it.
The main issue under discussion at the Trump-Kim summit will be North Korea's nuclear weapons, which the United States is demanding Pyongyang give up. "There is no way we will provide major economic assistance without resolving the abduction issue".
Vice President Mike Pence says North Korea has been dealing with the U.S.
Trump will need more than that in order to claim success. It's unclear how many are alive.
"It will not be there, no", he replied, when asked by a reporter if the summit would be held at the DMZ, which emerged as a possible candidate for the North Korea-U.S. meeting after the inter-Korean summit on April 27.
Hwang was 2 years old in December 1969, when his journalist father left for a business trip in Seoul.
Trump has vowed that he will not let that happen and has demanded that North Korea give up its nukes. But the North sent home only 39 of them and claimed that the remaining 11, including Hwang's father, wanted to stay.
They were detained in 2017 and charged with "hostile acts" against the North Korean state. He said he was able to communicate with his father through brokers in December 2012 and arranged a plan to smuggle him out across the Yalu River into China.
North Korea's foreign ministry said all of the tunnels at the country's north-eastern testing ground would be destroyed by explosion, and that observation and research facilities and ground-based guard units would also be removed. He said he last heard in 2016 that his father was still alive. The American, who was released in 2011, said he tried to commit suicide while in captivity.
The three were the latest in a series of Americans who have been detained by North Korea in recent years for seemingly small offenses and typically freed when senior US officials or statesmen personally visited to bail them out.
This time the visit was much lower-key. They will frame Trump's willingness to meet Kim as a welcome first step along the road to denuclearization; and they will return the gesture with some corresponding concession, such as a freeze on testing nuclear weapons or long-range missiles. He has said he is willing to "denuclearize" the Korean peninsula, but it is not clear he means what Washington means.
The abducted include South Korean government officials, businessmen, students and even a movie director and actress who both later escaped. One possibility is that he will confront Kim on North Korea's fluid definition of "denuclearization". Its lobby would be the base for Carol and me for the next almost 13 hours while Pompeo met and lunched with North Korean officials, including Kim. So do the North Korean people. "I think that if Kim Jong Un wants to find relief from "maximum pressure" and be welcomed back to the table of recognized global leadership, it's the only path he has".
North Korea's nuclear complex is significantly larger than Iran's.
"While most of the prisoners of war would be dead by now, numerous post-war abductees are likely alive", Choi said. We want to get peace. It was the first time that the leaders of China and Taiwan had met in over 60 years. South Korea says North Korea is holding at least three of them. That was a year before the North convicted Kim Kuk-gi and Choi Chun-gil on similar spying charges and also sentenced them to hard labour for life. South Korea also believes North Korea is detaining two North Korea-born citizens who had defected to the South.
