Chinese shares were slammed more than 4 percent lower on Friday after data showed exports contracting by a fifth, deepening fears for the world economy and pushing global equities to three-week troughs.
The February data, well below expectations of a 4.8 percent drop, worsened the brittle mood on world markets, following the European Central Bank's announcement slashing growth forecasts and unveiling a new round of policy stimulus.
While the timing of the Lunar New Year made it difficult to draw a true signal from the China data noise, the scale was alarming, especially when coupled with sombre new data from Germany and Norway.
Chinese stocks plunged more than 4 percent in their worst day in five months while Japan's Nikkei. closed 2 percent lower.
The dark mood spilled into European stock markets where the STOXX 600 index slipped 0.5 percent, poised for the first weekly drop in a month.
"The trade data from China is a big part of it," said Fiera Capital's co-chief Investment Officer Julian Mayo.
"Our own view is that the Chinese economy is slower than people generally think, but I think the world economy is probably slower than people think - so you put those two together and it is not surprising that the trade data was weaker than expected."
European auto stocks were at the forefront, slipping 1.6 percent, with an unexpected decline in German industrial orders adding to the China woes. Financials also nursed losses for a second day after the European Central Bank cut its growth forecasts and pushed out an interest rate hike.

Yet the cocktail of growth woes and dovish central banks proved a boon for bonds. Germany's benchmark 10-year bond yield took a step closer to zero percent and both German and French benchmark yields were at their lowest level since 2016 - the year that saw the ECB ramp up stimulus and cut rates to fight deflation and weak economic growth.
"The ECB has had a bullish impact on bond markets and that is set to continue," said Ciaran O'Hagan, rates strategist at Societe Generale in Paris. "We were not expecting something so clear, so soon, and markets were not either, so bond yields are likely to stay low for longer."
