The National Security Council of Japan on Monday approved disclosing some technical data on the nation's submarine technology to Australia, which is conducting a feasibility study on possible joint development and production of its next-generation submarine fleet.
The data to be disclosed will include specifications and performances of a submarine that Japan could develop with Australia, a senior Defense Ministry official said.
The scope of disclosure will be decided through negotiations, but it will be limited to what Canberra would need for its feasibility study, the official said.
