April 15 (UPI) -- North Korea on Wednesday accused Japan of a "grave provocation" after Tokyo expressed concern about Pyongyang's nuclear and missile programs in its annual diplomatic report.

Japan's Foreign Ministry said in its 2026 Diplomatic Bluebook that North Korea's weapons programs are a "serious and imminent threat" to Japan and the international community and are "absolutely unacceptable." The report, released last week, reiterated the need for the "complete, verifiable and irreversible dismantlement" of its nuclear arsenal and ballistic missiles.

The policy document also stressed the importance of fully implementing U.N. Security Council resolutions and warned that North Korea's transfer of weapons to Russia violates those measures.

An unnamed official at North Korea's Foreign Ministry called the assessment "a grave provocation encroaching upon the sovereign rights, security interests and development rights of our sacred state."
