Worries over a slowdown in China eased temporarily on Friday morning after a barrage of strong economic figures from the world's second-largest economy sparked decent gains in the mining sector in London. Chinese industrial production increased at an annual rate of 9.7% in July, an acceleration from the 8.9% rise in June and ahead of expectations (consensus forecast: +8.9%). This was the biggest jump since February "in a sign that the targeted investment by the government, in response to the slowing growth this year, is already having a positive impact," according to Market Analyst Craig Erlam from Alpari.Consumer-price inflation remained steady at 2.7% in July, in line with the increase in June and under the expected increase to 2.8%. With inflation still well below the 3.5% government target, analysts believe it leaves Beijing with room to implement more stimulus to boost growth.Not all data beat forecasts though this morning, with Chinese retail sales growth falling slightly from 13.3% to 13.2% last month (consensus forecast: +13.5%). However, Erlam said that the retail figures should still be viewed as another positive point: "The fact that we're seeing growth of 13.2% on the retail side is what is needed in order to pick up some of the slack from the lower demand for Chinese exports, due to the recession in the Eurozone and slowing growth in other countries."Yesterday, Chinese trade figures were well received by the market with both imports and exports smashing forecasts in July.Miners gain after China data Resource stocks were providing a lift on the FTSE 100 on Friday morning as the demand outlook improved on the back of the data from China.
