SEOUL • It is premature to say whether recent activity at some of North Korea's rocket facilities involved preparation for a missile launch, South Korea's Defence Minister told a parliamentary hearing yesterday.
Early in March, several American think-tanks and South Korean officials reported that satellite imagery showed possible preparations for a launch from North Korea's Sohae rocket launch site at Tongchang-ri, which has been used in the past to launch satellites but not intercontinental ballistic missiles capable of delivering a nuclear warhead.
"It's hasty to call it missile-related activity," Defence Minister Jeong Kyeong-doo told a parliamentary defence committee. "Tongchang-ri is a launch site but we don't see any activity being carried out for a missile launch."
When asked if he could confirm whether Sohae was functionally restored, Mr Jeong said it was inappropriate for the intelligence authorities to comment on every media report one way or the other.
He also said there were signs of continued nuclear activity in North Korea, without elaborating.
Unification Minister Cho Myoung-gyon told a separate parliamentary panel that it was possible the recent developments at the missile site were to bolster North Korea's leverage in negotiations.
"But given North Korea's continued work, thorough analysis is needed to find out its exact intentions," Mr Cho said.
He said that there have been signs of reconstruction at Sohae since late last year and that the rebuilding has now been done to a "substantial level".
Analysts at the James Martin Centre for Nonproliferation Studies in California said they estimated that the rebuilding at Sohae appeared to begin in earnest shortly before US President Donald Trump met North Korean leader Kim Jong Un at a summit in Hanoi last month.
The summit broke down because of differences over US demands for North Korea to denuclearise and North Korea's demand for substantial relief from international sanctions, imposed on the country because of its nuclear and missile tests.
Last Friday, North Korean Vice-Foreign Minister Choe Son Hui told foreign diplomats and journalists in Pyongyang that Mr Kim was considering suspending talks with the US and may rethink a freeze on missile and nuclear tests unless Washington made concessions.
Mr Trump said after his first summit with Mr Kim in Singapore last June that Mr Kim had promised to dismantle the Sohae test site, a pledge the North Korean leader reiterated and expanded on at a summit with South Korean President Moon Jae-in in September.
North Korea has used Sohae to launch satellites into space since 2011, and the US says its work there has helped in the development of missile technology.
