Japan should leverage its alliance with the U.S. to counter China*s threats rather than seeking quick compromises alone that will lead to long-term losses, according to an outspoken Japanese lawmaker whose entry into China has been banned.

If Beijing signals wielding rare earths restrictions as a weapon, Tokyo should hint that it could join forces with Washington to curb China*s access to semiconductor-making devices over which Japan retains supremacy, according to Hei Seki, a Japan Innovation Party lawmaker.

Seki sees slim chances for China to use that card like it did more than a decade ago against Japan, as the two nations verbally spar over Prime Minister Sanae Takaichi*s recent remarks on Taiwan. Many nations now see Beijing*s dominance over the critical minerals as problematic and a full-scale trade war with Japan will worsen China*s economic standing given its fragile trade truce with Washington.
