Europe's main stock markets fell at the start of trading on Wednesday after another slump in Shanghai.
London's benchmark FTSE 100 index fell 0.43 percent to 6,498.17 points compared with Tuesday's close.
Frankfurt's DAX 30 dropped 0.88 percent to 10,819.85 points and the CAC 40 in Paris shed 0.64 percent to open at 4,939.30.
Asian indices mostly fell Wednesday, led lower by Shanghai as investors fretted about waning Chinese state support for equities, while Tokyo grappled with weak trade data.
The dollar broadly weakened before the release of minutes from the US Federal Reserve's last meeting, which investors hope will offer fresh clues about the timing of an interest rate rise.
"European equity markets are trading lower... as once again weaker markets in Asia are souring sentiment for investors," said Markus Huber, senior analyst at brokers Peregrine & Black.
"Main focus today will be on the release of the... minutes and US inflation data," he added.
