Next month the last batch of televisions will roll off the production line at LG Electronics' plant in Thailand's Rayon province, just east of Bangkok. The company said on Tuesday that it's moving production 1,500 kilometers northeast to the Vietnamese coastal city of HAI Phone, where labor costs are cheaper and China-based suppliers that much closer. The move is part of a downward trend for Thailand's once-booming electronics industry that is struggling to find a foothold in the global supply chain for modern technology like smartphones and tablet computers. In January, the country's manufacturing index fell for the 22nd consecutive month, with production of goods like televisions and radios down 38 percent year-on-year. The decline is raising concerns that Thailand's economic slowdown is not a temporary problem caused by its political upheaval, but a structural one caused by the manufacturing industry’s failure to adapt and the increasing attractiveness of its lower-cost neighbors.
