Seoul/Washington, Oct 21 (TIWN) The US remains open to dialogue with North Korea, White House Press Secretary Jen Psaki said in a briefing.

Her remarks on Wednesday came after after North Korea announced a successful test launch of a submarine-launched ballistic missile (SLBM) that some believe may be a "game changer", reports Yonhap News Agency. 

"(It has) consistently been our view. So we've stated our openness to having those discussions with North Korea for months now," Psaki said in a press briefing onboard the Air Force One.  North Korea on Wednesday reported that it has successfully test fired a new SLBM the day before.  SLBMs are considered to reflect an increased threat to the US as they may require less distance to reach the mainland US.  Many, however, believe North Korean SLBMs do not pose an immediate threat to the US as the impoverished North is said to have only outdated, diesel-powered submarines that are easily detected. 

The US Indo-Pacific Command earlier said the latest North Korean missile did not pose an immediate threat to American personnel or territory.
