The Sino-ri site, which has not been disclosed by the hermit nation, is home to various medium-range missiles that could be used to attack South Korea, Japan and the US territory of Guam, according to a report. The discovery has cast doubt over whether North Korea has any intention of getting rid of its missiles despite agreeing to denuclearisation talks with President Trump. The report, which has been co-written by analyst Victor Cha, said: “The Sino-ri missile operating base and the Nodong missiles deployed at this location fit into North Korea’s presumed nuclear military strategy by providing an operational-level nuclear or conventional first-strike capability”.
The Sino-ri site is located 132 miles north of the demilitarised zone separating the two Koreas and is a seven-square mile base home to the Nodong-1 medium range missiles.
Washington-based think tank Centre of Strategic and International Studies fear there could be 19 more secret missile operating sites.
Mr Cha also said: “The North Koreans are not going to negotiate over things they don’t disclose.
“It looks like they’re playing a game. They’re still going to have all this operational capability.”
The White House announced last week that President Trump and Kim Jong-Un would meet in February to further denuclearisation.
Mr Trump said: “Kim Jong-un is looking very forward to it and so am I.
“We have made a lot of progress as far as denuclearisation’s concerned. Things are going very well with North Korea.”
And only on Sunday, Trump tweeted: “The Media is not giving us credit for the tremendous progress we have made with North Korea.
“Think of where we were at the end of the Obama Administration compared to now”.
Kim vowed to work towards denuclearisation in his first summit with President Trump in June, but little progress has been made.
