TOKYO (AP) — Talks between the United States and Japan on a Pacific Rim trade pact have halted for now without any resolution in sight, spoiling plans for a showcase deal during President Barack Obama’s visit to Tokyo.

Economy minister Akira Amari, Japan’s top negotiator, said too many issues remained unresolved and further working-level talks will be needed to reach a market-opening pact as part of the Trans-Pacific Partnership.
