Against the background of North Korea's missile launches, the United States announced its readiness to negotiate with the DPRK.

This was told by U.S. Defense Ministry spokesman John Kirby on Fox News.

Thus, on January 30, the military of Japan and South Korea conducted the seventh missile launch since the beginning of this year.

After that, the U.S. made a direct appeal to North Korea to join direct talks with no preconditions about its nuclear and missile programs.

According to the spokesman of the U.S. Department of Defense, the United States are discussing options for responding to Pyongyang missile launches with Japan and South Korea.

"We must make sure that our allies on the Korean peninsula are strong. We remain committed to the denuclearization of the Korean peninsula, as well as to the negotiations with Pyongyang. We are ready to sit down at the negotiating table without preconditions," said John Kirby.

The missile fired on Sunday appeared to be the most powerful since Biden took office, as Pyongyang revives its playbook of brinkmanship to wrest concessions.

The Japanese and South Korean militaries said the missile was launched on a high trajectory, apparently to avoid the territorial spaces of neighbors, and reached a maximum altitude of 2,000km (1,242 miles) and traveled 800km (497 miles) before landing in the sea.

The flight details suggest the longest-range missile since 2017, when North Korea twice flew ballistic missiles over Japan and, separately, three that showed potential to reach deep into the US. North Korea has launched seven times this month.
