(Central News Agency, Tokyo, 9th, Comprehensive Foreign News) The Japanese government held a meeting on the 8th to discuss the revision of three security-related documents, including the National Security Strategy, exchanging views on diplomacy and defense for about an hour and a half. However, opinions were divided on whether to include an evaluation of revising the 'Three Non-Nuclear Principles' regarding nuclear deterrence.
According to the Mainichi Shimbun, the coalition agreement signed between the Liberal Democratic Party and Nippon Ishin (Japan Innovation Party) includes an early revision of the three security-related documents. The Japanese government is therefore proceeding with the relevant work and plans to revise the documents within the year, based on the recommendations of both parties and discussions in expert meetings.
The meeting, held at the Prime Minister's Office on the 8th, was named the 'Expert Meeting on Comprehensive National Power for Security Considerations.' This was its second session, chaired by Kenichiro Sasae.
According to one participant, one member argued for evaluating the revision of the 'non-introduction' part of the Three Non-Nuclear Principles, stating, 'How to incorporate the evaluation of revising the Three Non-Nuclear Principles is a very important issue.' Another member also expressed the view that 'if the United deems it necessary, this principle should be reviewed.'
The Three Non-Nuclear Principles are Japan's basic nuclear policy, namely 'not possessing, not producing, and not introducing' nuclear weapons. The current National Security Strategy states that 'the basic policy of adhering to the Three Non-Nuclear Principles will not change in the future.'
On the other hand, several members argued that while they do not oppose discussing the evaluation of the principles, the current principles should be maintained.
Professor Atsuko Higashino from the University of Tsukuba told reporters after the meeting, 'Evaluating the revision of the Three Non-Nuclear Principles is not something that should be included in this revision of the three security documents, and it should not be promoted at this stage.'
The meeting also touched on promoting the 'Free and Open Indo-Pacific' (FOIP) concept, utilizing artificial intelligence (AI), and responding to cognitive warfare.
According to Jiji Press, Chief Cabinet Secretary Minoru Kihara stated at a press conference on the 9th that he would not comment on the opinions expressed at the meeting.
He stated that the Japanese government's position is to adhere to the Three Non-Nuclear Principles as a policy guideline.
When asked whether the government would consider actually revising the Three Non-Nuclear Principles in conjunction with the revision of the three security documents, Kihara only responded, 'At this point, we do not prejudge the specific content of the revision.' (Compiled by Yang Weijing) 1150609
