Stock indices closed lower on the further yuan devaluation. The yuan devaluated 1.6% against the U.S. dollar on Wednesday, after a 1.9% depreciation on Tuesday.

The central bank said on Tuesday that it was a "one-off depreciation".

"Looking at the international and domestic economic situation, currently there is no basis for a sustained depreciation trend for the yuan," the central bank said on Wednesday.

A weaker yuan should help to boost the activity in the manufacturing sector and exports, which dropped 8.3% year-on-year in July.

Meanwhile, the economic data from the Eurozone was weaker than expected. Industrial production in the Eurozone fell 0.4% in June, missing expectations for a 0.2% decline, after a 0.4% drop in May.

The decrease was driven by a drop in durable consumer goods and capital output. Durable consumer goods were down 2.0% in June, while capital goods output slid by 1.8%.

On a yearly basis, Eurozone's industrial production gained 1.2% in June, missing expectations for a 1.5% rise, after a 1.6% increase in May.

The increase was driven by a rise in non-durable consumer goods, capital goods and intermediate goods. Non-durable consumer goods climbed by 2.2% in June from a year ago, capital goods rose by 1.7%, while intermediate goods output gained by 0.2%.
