Nation 'should keep an eye on capital outflow'

China should be vigilant against capital outflow even if the chances of that happening are limited, experts said, after United States Federal Reserve Chairman Ben Bernanke reiterated his stance of tapering off the quantitative easing measures.

On Wednesday, Bernanke said the US central bank would carry on with its plan to start scaling back its bond-purchasing stimulus program later this year, although not on a fixed schedule.

"Our asset purchases depend on economic and financial developments. They are by no means on a preset course," Bernanke said in his prepared semi-annual testimony before the House Financial Services Committee.
