Samsung Electronics and SK Hynix led a sharp decline in South Korean chip stocks as concerns tied to China weighed on the semiconductor sector. The selloff hit two of the country's most important memory-chip makers, adding pressure to the broader market.

Samsung shares fell 13.4% on Tuesday, according to the report snippet, while SK Hynix also dropped heavily in the same trading session. Their declines were part of a wider regional semiconductor rout, showing that investor anxiety was not limited to a single company.

The weakness in the two chip leaders helped drag South Korea's KOSPI lower by 10.8% during the session, underscoring how much influence major technology exporters have on the country's benchmark index. When Samsung and SK Hynix come under pressure, the broader South Korean market often feels the impact quickly.

The move reflects rising unease around China-related risks for the chip industry, especially for companies tied to memory and high-bandwidth semiconductor demand. With both Samsung and SK Hynix at the center of the sector, the steep losses highlighted how sensitive Asian tech shares remain to shifts in sentiment around the semiconductor outlook.
