South Korea and the United States have been discussing a shipbuilding tie-up that could include investments to modernise U.S. shipyards and more help to repair the U.S. naval fleet as Seoul seeks better tariff terms,

South Korea is trying to secure a mutual trade package with President Donald Trump before August 1, when U.S. tariffs on Korean exports are set to snap back to 25%. The presidential office in Seoul said on Saturday that officials are preparing a deal they hope both countries can agree on ahead of minister-level meetings
