SEOUL, May 28 (Reuters) - Round-up of South Korean financial markets:

** The benchmark KOSPI rose 5.19 points, or 0.19%, to 2,728.18 by 0211 GMT, building on its 1.3% jump on Monday.

** The index traded in a narrow range as investors awaited more cues after a U.S. market holiday on Monday. European stock markets firmed on Monday.

** South Korea's finance minister said authorities would put forward detailed tax incentives under corporate reforms aimed at boosting the value of listed companies after seeking more feedback from market participants in coming months.

** Monday's geopolitical events of a rare trilateral summit with Japan and China and a failed satellite launch by North Korea left little impact on South Korea's financial markets.
