North Korea denounced the extension of the US-Japanese atomic energy agreement, accusing Tokyo of undertaking activities allegedly aimed at nuclear weaponization and blaming the United States of double standards, local media reported on Sunday.

Axar.az informs, the Korean Central News Agency reported.

The Korea Asia-Pacific Peace Committee (KAPPC) released a white paper on Saturday criticizing the 1988 US-Japanese nuclear pact, which was extended last month.

According to the white paper, Japan has been conducting nuclear research since long ago, allegedly starting to push forward the A-bomb development in 1930s.

The paper also suggested that out of 518 tonnes of plutonium stockpiled around the world so far, 47 tonnes are stored by Japan.
The document accused the United States of a double-standard approach to treat North Korea and Japan differently on nuclear issues, calling on Washington to "judge the situation from a fair stand" if it wanted denuclearization of the Korean Peninsula.

In July, the United States and Japan extended a bilateral nuclear cooperation agreement, which granted Japan the right to extract plutonium, reprocess spent fuel and enrich uranium on the condition that it was not used to build nuclear weapons.
