China's producer price index (PPI), which measures costs for goods at the factory gate, saw a significant narrowing in its year-on-year decline in May, with a drop of 1.4 percent compared to a 2.5-percent decrease in the previous month, official data showed.

The National Bureau of Statistics (NBS) attributed this to rising international commodity prices and improved supply-demand conditions in the domestic market of industrial goods.

On a monthly basis, the PPI edged up 0.2 percent in May, reversing a decline of 0.2 percent a month earlier and ending a six-month streak of continuous decreases, the data showed. (Xinhua)
