SEOUL, South Korea (AP) — South Korea’s government has expanded its back-to-work orders against thousands of cargo truck drivers who are staging a nationwide walkout over freight fare issues. The government says a prolonged strike could inflict “deep scars” on the country’s economy. The orders were initially issued on some 2,500 cement truckers last week. But they were expanded Thursday to about 6,000 drivers transporting steel and 4,500 transporting fuel and chemicals. Police are also clamping down on unionists who threaten or disrupt colleagues who choose to work. The strike’s impact has so far been mostly limited to domestic industries like construction.
