Australia's closed at a five-year high while the Shanghai Composite and the Kospi added 0.2 percent each but Japan's Nikkei and Indian stocks both posted modest losses.

For the week, Australia was Asia's best-performing index with gains of 0.6 percent while the Shanghai Composite posted the worst performance with a 1.4 percent loss.
