, Thailand is the largest exporter of computers and computer components in ASEAN. Thailand is the world's second-biggest maker of hard disk drives (HDDs) after China, with Western Digital and Seagate Technology among the biggest producers. But problems may loom for Thailand's high-tech sector. In January 2015, 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. Manufacturers are relocating to nations where labour is cheaper than Thailand. In April 2015, production will cease at an LG Electronics factory in Rayong Province. Production is being moved to Vietnam, where labour costs per day are US$6.35 versus US$9.14 in Thailand. Samsung Electronics Co. Ltd. will site two large smartphone factories in Vietnam. It made around US$11 billion worth of investment pledges to the Vietnamese economy in 2014. As technologies evolve, e.g., as HDDs are replaced by solid-state drives (SSDs), manufacturers are reexamining where best to produce these latest technologies. In addition, 74 percent of salaried workers in the sector face a high risk of being replaced by robots, as these positions consist of "repetitive, non-cognitive tasks".
