The US remains open to dialogue with North Korea,  said White House Press Secretary Jen Psaki in a press briefing. Psaki’s remarks on Wednesday came after North Korea announced a successful test launch of a submarine-launched ballistic missile that some believe may be a "game-changer", the reports quoted.

"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 on board the Air Force One. North Korea on Wednesday reported that it has successfully test-fired a new Submarine-launched ballistic missile (SLBM) the day before. It is e considered to reflect an increased threat to the US as they may require less distance to reach the mainland US. The US Indo-Pacific Command earlier said the latest North Korean missile did not pose an immediate threat to American personnel or territory.

Many, however, believe North Korean ballistic missiles do not pose an immediate threat to the US as the impoverished North is said to have only outdated, diesel-powered submarines that are easily detected. Tuesday's missile launch marked the eighth known missile test by the North this year. The country also test launched what it claims to be a new hypersonic missile late last month.
