SEOUL (Reuters) -South Korea's industry minister said on Monday that the country managed to avoid the worst-case scenario by clinching a U.S. tariff deal, but concerns remained over how the profitability of exporters would be affected by a 15% tariff rate.

Industry minister Kim Jung-kwan made the comments at a roundtable meeting with business groups and academics.

"There are concerns that the unprecedented 15% tariff will have a significant impact on the profitability of companies exporting to the U.S., especially small and mid-sized companies, compared to local U.S. companies," Kim said in his opening remarks.

Under its deal with U.S. President Donald Trump, South Korea also agreed on a $350 billion investment package, including $200 billion in strategic industries such as semiconductors. The rest was earmarked for the U.S. shipbuilding industry.

Kim said that the government would continue discussions with the U.S. to work on the specifics of the investment package so it would benefit the country's economy and companies.

There is no written agreement yet on the deal between Seoul and Washington, and more follow-up discussions were needed on the investment fund's structure among other details, South Korean officials have said.

Regardless of the tariff deal, South Korea will seek a long-term strategy in the face of a new normal era where nationalism is expanding in the global trade environment, Industry Minister Kim said.
