In a meeting in Singapore on Friday, Prime Minister Shinzo Abe told U.S. Vice President Joseph Biden about a plan to set up an NSC-type institution to lead policymaking on security.

But pursuing the legislation may be hard as New Komeito, the junior partner in Abe’s ruling coalition, is said wary of the plan.
