US positive on N. Korea denuclearization despite 'operational' rocket site

WASHINGTON (AFP) – The US still believes the ''fully verified denuclearization'' of North Korea is possible by the end of President Donald Trump's ''first term,'' a senior official said Thursday, despite warnings a key rocket launch site appears to have resumed operations.

The specialized website 38 North and the Center for Strategic and International Studies used commercial satellite imagery to track construction at the site – which they said began before last week's aborted summit in Hanoi between Trump and North Korea's Kim Jong Un.

Images taken on March 6 showed that a rail-mounted structure to transfer rockets to the launching pad appeared to have been completed and ''may now be operational.''

Cranes have been removed from the pad, while progress also appeared to have been made on rebuilding the support structure for a rocket engine testing stand.

''Given that construction, plus activity at other areas of the site, Sohae (Satellite Launching Station) appears to have returned to normal operational status,'' 38 North's report said.

The news will compound the White House's frustration over the lack of progress on talks with the North, following the collapse of a second Trump-Kim summit without so much as a joint statement, let alone an agreement on nuclear disarmament.

The official confirmed that Washington would seek from Pyongyang ''clarifications on the purposes'' of rebuilding the site.

''We don't know why they are taking these steps,'' the official said, requesting anonymity.

Kim had agreed to shutter Sohae at a summit with the South's President Moon Jae-in in Pyongyang as part of confidence-building measures, and satellite pictures in August suggested workers were dismantling the engine test stand.

Trump equivocated when asked Thursday if he was disappointed about the news. ''We'll see,'' he said. ''We'll let you know in about a year.''

The president had declared that it was ''too early'' to tell if a previous report about activity at the site was true, but said he would be ''very, very disappointed in Chairman Kim'' if the intelligence checked out.

US media had speculated over whether Trump might tighten the thumbscrews on Pyongyang following the Vietnam summit, by ratcheting up an already crippling sanctions regime.

State Department spokesman Robert Palladino affirmed Washington's commitment to stay engaged with Kim, however, telling journalists on Thursday the administration was ready for ''constructive negotiation.''

And despite the apparent setback, the senior official insisted ''we still believe this (denuclearization) is all achievable within the president's first term.'' Unless re-elected, Trump's term will end in January 2021.

''We have sufficient time,'' the official said, without mentioning a deadline for reaching an agreement so the goal could be met.
