SEOUL--North ‍Korea said Japan's ambition for possession of nuclear weapons should be "thoroughly curbed," state media ‍KCNA ​reported on Sunday.

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.

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, U.S. 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.
