Asian stocks mixed

HONG KONG: Asian stocks were mixed, as China announced new rules restricting short selling after a recent market rout and Australia held interest rates at rock-bottom levels.
Tokyo eased 0.14 percent or 27.75 points to close at 20,520.36, while Seoul gained 0.97 percent or 19.50 points to close at 2,027.99. Hong Kong rose 0.15 percent while Shanghai jumped 3.69 percent.
