SEOUL, Sept 3 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares rose more than 1% on Thursday and extended gains to a third straight session as strong foreign buying powered local chip stocks. Both the won and the benchmark bond yield weakened.
** The benchmark KOSPI closed up 31.53 points, or 1.33%, at 2,395.90.
** Chip giant Samsung Electronics Co Ltd ended 3.7% higher, tracking a surge in the Philadelphia Semiconductor index, after Nvidia Corp's announcement on its new gaming chips in collaboration with Micron Technology Inc and Samsung.
** Samsung's peer SK Hynix Inc and the subindex for electric and electronics stocks jumped 4.2% and 3.2%, respectively.
** Further boosting sentiment, South Korea's government announced a plan to create a 20 trillion won ($16.84 billion) fund over the next five years for President Moon Jae-in's "New Deal" program.
** "Strong gains in local semiconductor shares towed KOSPI, especially with active foreign buying of Samsung Electronics shares," said Lee Young-gon, Hana Financial Investment analyst.
** The "New Deal" fund and fewer daily coronavirus infections also lifted sentiment, Lee added.
** Foreigners were net buyers of 194.0 billion won worth of shares on the main board.
