WASHINGTON (REUTERS) - One of 20 undeclared ballistic missile operating bases in North Korea serves as a missile headquarters, according to a report by the Center for Strategic and International Studies (CSIS) published on Monday (Jan 21).
"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 report said.
The discovery of an undeclared missile headquarters comes three days after US President Donald Trump announced last Friday that he "looks forward" to another summit to discuss denuclearisation with North Korean leader Kim Jong Un in late February.
CSIS, which last reported on the 20 undeclared bases in November, said the Sino-ri base has never been declared by North Korea and as a result "does not appear to be the subject of denuclearisation negotiations".
The report noted that missile operating bases would presumably be subject to declaration, verification, and dismantlement in any denuclearisation deal.
"The North Koreans are not going to negotiate over things they don't disclose," said Victor Cha, one of the authors of the report.
"It looks like they're playing a game. They're still going to have all this operational capability," even if they destroy their disclosed nuclear facilities.
Located 132 miles (212 km) north of the demilitarised zone, the Sino-ri complex is a seven-square-mile (18-square-km) base that plays a key role in developing ballistic missiles capable of reaching South Korea, Japan, and even the US territory of Guam in the Western Pacific, the report said.
It houses a regiment-sized unit equipped with Nodong-1 medium-range ballistic missiles, the report added.
The White House did not immediately respond to a request for comment.
Satellite images of the base from Dec 27, 2018 show an entrance to an underground bunker, reinforced shelters and a headquarters, the report said.
