(Reuters) - European shares opened lower on Wednesday 7 September 2022, with miners and energy firms leading losses, as investors fretted over demand outlook following lacklustre trade data from China.

The European oil & gas index was down 2.2%, as of 07:20 GMT (09:20 GMT+2), while miners lost 2.3%.

Both sector indexes led declines in the benchmark STOXX 600 index, which dropped 0.9% after notching marginal gains in the previous session.

Data from China showed exports and imports had slowed in August 2022 with growth largely missing forecasts as sky-high inflation hindered overseas demand and fresh COVID-19 curbs and heatwaves disrupted output.

European markets have been widely affected by worries of an energy crisis amid soaring prices and the stoppage of Russia's biggest natural gas pipeline to the region.
