The finance chiefs urged the Greek parliament to approve the austerity measures agreed by the political parties when it convenes on Sunday.

"The trade data is not affecting the market much because investors know it was distorted by the Lunar New Year holiday," Minsheng Securities analyst Zhang Lei told Dow Jones Newswires.
