Germany, Europe's export powerhouse, is bearing the brunt of an economic slowdown in China and a global trade war initiated by U.S. President Donald Trump's administration.

The Bundesbank estimates the German economy expanded by just 0.6% last year, which would make it its worst year since 2013, when the euro zone was only starting to emerge from a debt crisis that almost brought down the euro.

Manufacturing activity, Germany's forte in the recent boom years, "declined strongly and in a broad range of sectors" as exports and capital investments suffered, the Bundesbank said.

On the upside, the services sector and construction continued to boom, the German central bank added.
