Guess who's whining? China filed a WTO complaint (WT/DS623) against the US IRA earlier this year, accusing the US of violating what China has violated past 10 years.
The EU is also working on theirs, called CRMA approved earlier this year, but nothing that would match Papa Xi's blatant protectionism; or China's annual $270B fossile fuel subsidies to support cheap energy or overcapacity; or China's insatiable appetite for coals and carbon emission.
