SEOUL, June 12 (Reuters) - South Korean prosecutors said they indicted a former Samsung Electronics (005930.KS) executive on Monday on suspicion of stealing the company's technology to build a chip factory in China. He worked a combined 28 years at the South Korean chipmakers, prosecutors said. The attempt to build the new plant using Samsung data, however, ended in failure due to funding issues, a prosecutor said. South Korean President Yoon Suk Yeol has described competition in the industry as an "all-out war" amid heightened Sino-U.S. tensions. South Korea's Samsung and SK Hynix, the world's top two makers of memory chips, have invested billions of dollars in chip factories in China.
