Rather, Kim said, the existence of such a missile site shows the need for talks with North Korea to get rid of its military threats.
The sites, identified using satellite images, can be used to develop weapons ranging from short-range ballistic missiles to intercontinental ballistic missiles, according to the report published by the Beyond Parallel program at the Center for Strategic and International Studies on Monday.
Japan, which has called on the worldwide community to maintain pressure on Pyongyang, is supportive of the United States' latest stance on the annual military drills that Trump indefinitely suspended following his first-ever summit with North Korean leader Kim Jong Un in mid-June in Singapore.
Although the sites are not usually used for missile launches and in some cases are rudimentary, the authors of the report from the Centre for Strategic and International Studies say they are hidden and illustrate the scope of the North's weapons program and the country's determination to hide its military might.
One of the sites in question is the Sakkanmol Missile Operating Base, which sits about 85 miles from the Demilitarized Zone between North and South Korea.
"It's not like these bases have been frozen", Victor Cha, who leads CSIS's North Korea program, told The New York Times, which first reported on the study.
"What everyone is anxious about is that Trump is going to accept a bad deal".
Cha had been in line for appointment as U.S. ambassador to South Korea, but was dropped because of disagreement with the Trump administration's approach.
"It implies a message that 'We know all the missile facilities in North Korea".
The bases, which are scattered across the country, are located in underground facilities tunneled in narrow mountain valleys, according to the researchers. "While missiles could be launched from within them in an emergency, Korean People's Army operational procedures call for missile launchers to disperse from the bases to pre-surveyed or semi-prepared launch sites for operations".
Trump Signs Order Denying Asylum to Illegal Border Crossers 9 November 2018
Omar Jadwat, director of the American Civil Liberties Union's Immigrants' Rights Project, said Thursday they were clearly illegal. About 4,800 migrants are sheltered in a sports complex in Mexico City, some 600 miles (965 kilometers) from the US border.
North Korea has for a long time slammed joint military exercises between the US and South Korean forces as rehearsals for invasion, and regional tensions nearly every year had escalated around spring.
Bases for shorter range missiles fit into a tactical belt 30 to 55 miles from the DMZ.
The researchers' findings were based on satellite imagery, defector interviews and interviews with intelligence and government officials. But a report based on satellite imagery shows the complexity posed by an extensive network of weapons facilities that the USA wants to neutralize.
"Missile operating bases are not launch facilities", Bermudez wrote.
He added that the regime is also reinforcing protection to prepare for precision attacks from South Korea and the USA and is repairing roads so that mobile launchers can move fast and fire ballistic missiles.
Trump has said he hopes to meet again soon with Kim, but there are signs of growing friction in the negotiations with North Korean officials, which appear to have stalled.
North Korea last week asked for a planned meeting between US Secretary of State Mike Pompeo and Kim's right-hand man Kim Yong Chol to be delayed. While other countries use bombers and submarines to field their nuclear weapons, North Korea is believed to rely nearly entirely on trucks.
But to some analysts, North Korea never explicitly agreed to that, only to the more vague term "denuclearization".
