There are concerns the North is preparing to conduct its fourth atomic detonation, with recent satellite images showing stepped-up activity at its main nuclear test site.
Obama's tour, which ended Tuesday in the Philippines after taking in Japan, South Korea and Malaysia, "was a dangerous one as it was aimed to bring dark clouds of more acute confrontation and nuclear arms race to Asia", a Pyongyang foreign ministry front man said in a statement official to state run Korean Central News Agency (KCNA).
Pyongyang would bolster its nuclear deterrent "now that the US brings the dark clouds of a nuclear war to hang over the DPRK (North Korea)", the front man said.
"There is no statute of limitations to the DPRK's declaration that it will not rule out a new form of nuclear test clarified by it in the March 30 statement," he added.
The "new form" of nuclear test could perhaps lay the stage for a test based on new uranium-enrichment technology, analysts have said.
Obama's tour "was designed for undisguised confrontation to retain a tighter grip on allies of the U.S. and encircle and contain its rivals in Eurasia, pursuant to the U.S. Asia-Pacific strategy for domination and scenario for aggression from A to Z," the front man added.
