SEOUL, Aug 30 (Reuters) - Round-up of South Korean financial markets:

** U.S. job openings dropped to the lowest level in nearly 2-1/2 years in July, data showed on Tuesday, bolstering expectations that the Federal Reserve will keep interest rates unchanged next month.

** "The domestic market is tracking U.S. tech stocks' strength after a fall in bond yields, but its rise is not as strong ahead of U.S. payrolls and domestic trade data," said Huh Jae-hwan, an analyst at Eugene Investment Securities.
