Fifteen economies start their overcapacity pact on EVs, batteries and solar with data-sharing

The statement's central demand is about other governments' policies. "We call on all countries to take steps to eliminate structural excess capacity and production in their economies, including by ending the use of nonmarket policies and practices that distort markets and contribute to the problem," it said ^[9]. The technical meetings before December are meant to settle how the platforms will operate and to share nonconfidential information on overcapacity and its impact on members' industries ^[12].

Each platform is meant to analyze the scale of overcapacity and its effect on markets, and to discuss specific responses ^[11]. Sizing the surplus comes first in that brief. For a buyer of battery cells or solar modules, that order matters, because a shared estimate of surplus is evidence each government could later use in its own trade measures. The statement does not say which signatory would act first, or under what law.

The first possible outcome is that the platforms produce common numbers and members use them in their own cases against imports. Barriers would then arrive one country at a time, built on shared evidence. In the second, the platforms remain a forum and each signatory keeps setting trade policy much as it did before. The third is that Beijing moves first; the South China Morning Post reported warnings that China could retaliate ^[19].

I'd expect the second outcome for the rest of this year. The statement does not name China ^[7]. The platforms are open to economies outside the OECD, as India and Argentina already are ^[11]. A group still writing its operating rules has little time to agree a sector response before G20 leaders meet in Miami in December ^[18]. The case against that view is in the USTR's version of the text, which commits the 15 to "take effective actions" ^[4]. If that phrase turns out to mean coordinated measures, the platforms are a formality and the first outcome arrives sooner. A platform naming a specific response in any one sector before the Miami summit would prove this view wrong.

Korea's trade ministry described its plans in procedural terms. "We plan to take an active part in building the sectoral cooperation platforms and in follow-up discussions, and to work closely with major countries, to respond effectively to the global overcapacity problem," an official at the Ministry of Trade, Industry and Resources said ^[17].
