However, new South Korean President Moon Jae-in's administration has not taken up the plans, according to the newspaper.
The lurid accusations came amid continuing high tensions over the North's nuclear and missile programmes and with Washington considering whether to re-designate Pyongyang as a state sponsor of terrorism. Moon was elected just last month in a snap election following the historic impeachment and removal of conservative President Park Geun-hye.
Moon, set to arrive on Wednesday afternoon, has long favored engaging North Korea despite its rapidly advancing nuclear capability. Moon, a liberal who took office in May, has expressed a desire to reach out to North Korea, but its continuing missile tests pose a hard challenge for him. He called on China and Russian Federation to serve as links to North Korea, noting that they share a border.
China is pushing the United States to start negotiations with the North.
Meanwhile, Trump is reportedly growing increasingly frustrated with China. Nor has there been any headway between the two Koreas toward negotiations, because North Korea has continued to launch missiles and test rocket engines all year. Moon and his wife, Kim Jung-sook, will be hosted on Thursday evening by Trump and the First Lady at the White House, ahead of what promises to be a challenging day of talks on Friday.
Upon landing in the U.S., Moon is scheduled to visit a memorial at the National Museum of the Marine Corps in Quantico, Virginia, commemorating the Battle of Chosin Reservoir at the height of the 1950-53 Korean War, which is remembered as a high point in the history of the U.S. Marines Corps as well as one of the fiercest battles the United Nations coalition forces waged during the three-war conflict.
The memorial commemorates a fearless rearguard action by Marines during that bitter winter as Chinese troops advanced.
South Korea is now running 24 nuclear reactors after it permanently closed its oldest nuclear reactor, Kori No.1, last week.
The U.S. military already has installed key components of the anti-missile battery in Seongju, but Moon suspended the process with four launchers left in limbo pending a full environmental assessment.
The official Korean Central News Agency said North Korea will impose a "death penalty" on ousted South Korean President Park Geun-hye and former spy chief Lee Byoung Ho, and they could receive a "miserable dog's death any time, at any place and by whatever methods from this moment".
North Korean propaganda often contains extreme claims.
Despite a lack of progress, Moon stands by his conciliatory approach.
Chung, however, noted the most important goal, if not an outcome, of the summit is for the two leaders to form a personal friendship that would enable such discussions over the next five years.
But there's no sign North Korea has any intention of suspending its nuclear weapons development. Bullet holes are still visible on a tree above the presidential Blue House.
Pyongyang has repeatedly hinted that negotiations and dialogue would be possible on conditions that the USA administration abandons its deep-seated hostilities against the DPRK.
While South Korean President Moon Jae-in remains adamant that sanctions alone will not curb North Korea's nuclear program, his failed attempts to re-establish a dialogue with Pyongyang have stirred concerns in the U.S.
The list included Lee, two other South Korean intelligence officers and Xu Guanghai of the Qingdao Nazca Trade company, as suspects whose extradition was demanded by Pyongyang.
"Now we have new leadership in Seoul and Washington, it is a time to kind of open the aperture a bit", Kathleen Stephens, a former USA ambassador to South Korea, said Monday during a forum in Seoul.
At a recent high-level meeting in Washington, a person who was briefed on the session said, the Americans handed the Chinese a list of companies that were dealing with the North Koreans and told them "to handle it - or else".
Moon's visit will not be all about North Korea. "If he raises some contentious points, or says something out of the blue at the press conference or any number of other things - remember how the President Trump-President Xi talks were overshadowed by the sudden US strike in Syria".
