Ohio Republican Senator Bernie Moreno urged USTR Greer to consider imposing
tariffs on South Korea under Section 301 of the 1974 Trade Act, citing what he
called Seoul’s “openly hostile” treatment of US e‑retailer Coupang — including
heavy compliance burdens, excessive fines, criminal prosecutions of executives
and biased enforcement. Moreno asked Greer to open a Section 301 probe; he noted
Section 301 was the authority Trump used to impose tariffs. He said such action
would further complicate trade talks with a key US ally. South Korea denies
discriminating against Coupang.
