The international community seeks to revive the nuclear deal, which has been in place for two years.
Top nuclear representatives from Japan, the United States and South Korea held talks in Tokyo on Tuesday to discuss nuclear weapons in North Korea, just a day after Pyongyang reportedly tested a new missile.
Investigators said the weapon, which North Korean journalists call “obvious”, could have the potential of nuclear weapons.

Biden’s policy would have been changed to work and focus on negotiations, officials said at the time.

Pyongyang said it did not see any sign of change from Washington.
