Accordingly, the firm is scheduled to shut down Pyeongtaek plant in the south of Seoul and shift its production line to the northern port city of Hai Phong.
The company currently manufactures smart phones in the RoK, Vietnam, Brazil and China while its domestic plants mostly produce premium devices.
LG Electronics has struggled in smart phone market for years amid intense competition with Samsung Electronics and Apple in hi-end segment and with Chinese manufacturers in the lower segment.
Last year, its sale of mobile devices hit US$1.5 billion but the loss amounted to 280 million USD due to weak revenue and rising marketing cost.
Meanwhile, the LG Display Co. said on April 24 that its net loss went up to $55 million in the first quarter this year, higher than the $42.5 billion in the same period last year due to low selling prices of liquid crystal displays.
