The revamped U.S.-South Korea accord unveiled earlier this week isn’t much different from the existing pact that Trump often condemned as “disastrous.” Most changes made to tariffs, automotive quotas and agricultural preferences were narrow in scope or incremental, according to trade experts. Trump has regularly threatened to cancel several trade deals -- including the one with South Korea -- if he didn’t secure major changes. Yet his willingness to accept modest revisions after demanding a wholesale overhaul indicates that other trading partners, including Mexico and Canada, may be able to satisfy his demands with smaller concessions. The White House highlighted South Korea’s agreement to double, to 50,000, the number of cars each U.S. automaker can sell in the Asian nation without meeting local safety standards. But in a briefing in South Korea, the country’s trade minister, Kim Hyun-chong, downplayed the significance of the concession, noting that no American company sells much more than 10,000 cars a year there and suggesting the current 25,000 ceiling isn’t an obstacle. While the deal will put a quota on South Korean steel sales to the U.S. to about 2.7 million tons annually, it’s unlikely to have a significant effect on the country’s exports, South Korea’s trade ministry said. Exports of steel to the U.S. account for 11 percent of total overseas shipments of the metal by the country.
