North Korea has called a Japan-South Korea summit held this month "military collusion."
In a commentary released on the website of the Committee for the Peaceful Reunification of the Fatherland on Wednesday, Pyongyang condemned South Korean President Yoon Suk-yeol for his "submissive" foreign policy.
The statement said, "The military collusion between South Korea and Japan has entered the stage for it to be recklessly carried out."
At the May 7 summit, Yoon and Japan's Prime Minister Kishida Fumio confirmed that bilateral security cooperation and trilateral cooperation involving the United States will be further strengthened.
The commentary said the US has built a triangular military alliance and laid the groundwork for a foothold toward its goal of forming the Asian version of NATO.
Pyongyang has repeatedly criticized the forging of closer trilateral ties between Japan, South Korea and the US while pressing ahead with its nuclear and missile development.
It has also made clear that it puts more emphasis on strengthening relations with Russia and China to counter the three countries.
