SEOUL, December 23 (AJP) - South Korea’s KOSPI rose slightly on Tuesday as Samsung Electronics closed at a record high, while Chinese and Japanese markets were little changed.

In Seoul, the benchmark KOSPI gained 0.3 percent to finish at 4,117.32, extending its winning streak to a third session. The tech-heavy KOSDAQ fell 1 percent to 919.56.

Samsung Electronics rose 0.9 percent to 111,500 won ($75.3), reaching the highest closing price in its history. SK hynix added 0.7 percent to 584,000 won.

U.S. President Donald Trump said Monday at Mar-a-Lago, Florida, that the Navy’s newly announced class of frigates will be built in partnership with South Korea’s Hanwha.
