Most Asian stock indices closed higher due to Friday's comments by the Fed Chair Janet Yellen. Janet Yellen said in Jackson Hole that the U.S. labour market is not yet fully recovered. But she added that the U.S. labour market was improving. The Fed Chair Yellen offered no signal when the Fed will start to raise its interest rate.

Investors speculate that the Fed may hike its interest rate sooner than expected.

Market participants continue to monitor developments in Ukraine. Russian President Vladimir Putin will meet Ukrainian President Petro Poroshenko in Minsk on Tuesday.
