Profits of China's major industrial firms in June totaled 666.55 billion yuan ($95.18 billion), increasing by 11.5 percent year on year, data from the National Bureau of Statistics (NBS) showed on July 27.

The growth widened 5.5 percentage points from that in May, NBS senior statistician Zhu Hong said.

The quickened growth in industrial production and sales and the moderate drop in the factory-gate prices of industrial products led to the expansion of profits in June, according to Zhu.

In the first half of the year, the profits of major industrial firms declined 12.8 percent to 2.51 trillion yuan ($358 billion), narrowing 6.5 percentage points from that in the first five months.

Specifically, profits of state-owned industrial firms dropped 28.5 percent from one year earlier to 661.41 billion yuan ($94 billion), while those of private ones shrank 8.4 percent year on year to 711.98 billion yuan ($101 billion).

During the period, profits of the mining industry slumped 41.7 percent, and manufacturing industry profits decreased by 9.8 percent.

Profits in nine of the 41 industrial sectors surveyed rose compared with one year earlier, while 31 sectors saw their profits fall, according to the NBS.
