North Korea is reportedly still upgrading one of its long-range missile bases.<br />And such activities are said to have been continuing even after the historic summit between the leaders of North Korea and the U.S. in June.<br />Park Hee-jun tells us more. If confirmed, it's another disappointing finding on North Korea's weapons activities.<br />According to CNN Wednesday, satellite imagery provided by the Middlebury Institute of International Studies at Monterey,... shows North Korea has been expanding a key long-range missile base in Yeongjeo-dong .<br />The base is in a mountainous region, just 20 kilometers south of the North Korea-China border. <br />Experts told CNN that the facility, which has long been familiar to the U.S., is a suitable location to receive the North's newest long-range missiles,... including those than can carry nuclear warheads to the U.S. mainland.<br /><br />The images not only reveal significant activity at the base,... but also the construction of a new, previously-unknown facility,... just eleven kilometers away from the Yeongjeo-dong base. <br />It's unclear whether they are separate sites,... or whether one is a sub-base to another.<br />The images also suggest North Korea was building a large underground facility in 2017,... and the regime continued construction up until this August.<br /><br />That means such activities were continuing even after the first North Korea-U.S. summit in Singapore in June.<br />There, North Korean leader Kim Jong-un and U.S. President Donald Trump agreed to work toward the denuclearization of the Korean Peninsula. <br />The newly-discovered activities could be an indicator that months of dialogue with the North has done nothing to stop the regime from developing its weapons programs. <br />And that,... raises questions on the progress being made in pushing Pyeongyang toward complete denuclearization, and on the need for a second Kim-Trump summit.<br />Park Hee-jun, Arirang News. <br />
