South Korea's Kospi opened down 179.64 points, or 3.17 percent, at 5,488.41 on Monday but had pared the loss to 1.36 percent by 09:23 local time as foreign and institutional buyers stepped in, Yonhap reported.

Why it matters: The partial recovery in Seoul is the first Asian read on whether Friday's semiconductor led selloff in the United States, the Philadelphia index's eighth straight fall and its longest losing streak since 2008, is stabilising or spreading.
