About 8,000 workers at a Chinese plant owned by the LG group went on strike claiming South Korean staff at the same unit were paid higher year-end bonuses than local workers.
This year the country faced a series of strikes demanding better pay as food and fuel prices have gone up.
LG explained that "We and the Nanjing city government are jointly negotiating with workers to smoothly reach an agreement and we expect the problems to be resolved soon."
