Protectionism is expected only to intensify under Trump, who in his first term exited a nascent Pacific-wide trade pact and has vowed to use tariffs to protect US industry.

Ishiba said Monday that the United States should “explain clearly” the security worries cited by Biden.
“There are concerns being raised within Japan’s industrial world over future Japan-US investment,” Ishiba warned in unusually outspoken comments.
