Weakening of key economies can lead to global slowdown, says Japan's Aso

Global policymakers worry that weakness in key economies could spread and cause the world economy to slow more than expected, Japanese Finance Minister Taro Aso said on Friday.

"The balance of risks remains skewed to the downside," Aso said in a news conference following a meeting of finance ministers and central bankers from the Group of 20 industrialized countries.

"We recognize the risk that growth prospects might deteriorate if weakening in key economies feed into each other."
