The government has protested against the U.S. Trade Representative's decision to ban imports of older Samsung smartphones. Samsung said it could appeal the decision.
The Ministry of Trade, Industry and Energy in a statement Wednesday said it "regrets" the U.S. government's decision, while Samsung said it is "disappointed" by the decision and considering "all options."
In August, the USTR ruled that Samsung infringed Apple's patented technology and ordered an import ban of the Galaxy S and S2 models. U.S. President Barack Obama earlier vetoed a similar ban of Apple phones for infringing Samsung patents, the first such veto in 25 years, but did nothing to veto the ITC decision against Samsung.
Critics say that is flagrant protectionism.
Bloomberg Businessweek reported that the White House did not give Samsung the "benefit" it gave Apple in August and voiced concerns that it could promote the view that Washington is biased against foreign business.
The Wall Street Journal said the U.S. government "ignored" Samsung's request for "fair treatment."
But analysts say the impact of the ban will be minimal, since it involves outdated models.
