The agreement that Japan secured has added pressure on South Korea to defuse the threat of high tariffs on its exports to the United States.

Seoul will take a close look at the terms of a U.S.-Japan trade deal, South Korea's industry minister said on Wednesday, holding out the prospect of greater cooperation in the energy and industrial sectors ahead of key trade talks in Washington.

South Korea, facing 25% tariffs, is rushing to reach a trade deal with Washington, with National Security Adviser Wi Sung-lac visiting the U.S. recently for high-level talks and Minister for Trade Yeo Han-koo also in the U.S. for negotiations, as pressure grows on officials to clinch a deal that is no worse than Japan's that cut tariffs to 15%.
