Japan and Britain plan to agree to forge a defense intelligence-sharing accord at a meeting of their leaders in Northern Ireland next week, while discussing the establishment of high-level bilateral talks, a government source said in Tokyo.

Prime Minister Shinzo Abe and his British counterpart, David Cameron, are also expected to agree on a pact to protect each other's sensitive technology, given plans to jointly develop chemical protective suits.

In April last year, the two sides struck a deal to jointly develop arms and defense equipment, following Tokyo's December 2011 decision to relax its ban on arms exports.
