Nippon Steel touted the $14.9 billion deal as a lifeline for its rusting US rival, but opponents warned that the Japanese firm would slash jobs -- despite assurances to the contrary.

Prime Minister Shigeru Ishiba said the veteran Democrat's decision had sparked worries over future Japanese investments in the world's largest economy.
