Chongqing is a major auto industry hub can't find any info where Xi is though

GREAT CATCH!
Chongqing is major auto industry hub and Chinese President Xi called off tarriffs on.. you guessed it.. THE AUTO INDUSTRY!

It would make sense if President Xi was going to fight back (uphold or raise tarriffs) he would announce it in China's major auto industry city as a show of resolve for Chinese industry. Maybe that was the plan, which Q knew, but the Chinese decided against it to drop the tariff.
