Japan ‌is ‌showing the intention ‌to possess nuclear weapons explicitly by saying it needs to review the three non-nuclear principles, KCNA said citing a commentary of North Korea’s foreign-policy official, Reuters reported.

Japan ‌began making such ‍comments ‍actively as soon as ‍the United States approved a request from South Korea for building a nuclear submarine, the media said.

In October, US President Donald Trump said he has given South Korea approval to build a nuclear-powered submarine, after his visit to the Asian ally for a summit on trade deala with South Korean President ‌Lee Jae Myung.
