US President Joe Biden speaks with Vice President Kamala Harris (left) and Secretary of State John Kerry (right) before a joint session of Congress. North Korea warned Sunday that the United States was facing a “very serious situation” after Biden made “a big mistake” by calling the North a security threat and revealing plans to pursue a hostile policy toward it, the official KCNA news agency reported. North Korean leader Kim Jong Un wants to convene a summit of diplomacy in response to his growing nuclear arsenal.

Diplomacy has stalled, and will not in about two years, as disagreements persist over how much sanctions relief North Korea could receive in exchange for limited steps toward denuclearization. Just hours after President Joe Biden warned of an escalation in tensions over Pyongyang’s stalled nuclear negotiations, Pyongyang confirmed the test of a new guided missile, according to the KCNA news agency. The missile, which has a range of 1,000 kilometers (1,200 miles), hit a target off the east coast on Thursday, it said.

A video of the rocket, which was lifted into flames by a transport rocket, shows it taking off from its launcher and landing in the sea.

North Korea unveiled a development missile designed to fire submarines and other military equipment during a parade interrupted by a speech by President Barack Obama on expanding the country’s nuclear arsenal and weapons program.

South Korea struck with a group of North Korean defectors in the South, who hovered leaflets with anti-Pyongyang slogans across the border. Easley said it showed Pyongyang was trying to drive a wedge between South Korea and the United States over its nuclear and missile programs.

On Friday, the group’s leader, Park Sang-hak, said he had sent 500,000 leaflets across the border to defy a controversial new South Korean law that criminalizes such actions.
