China Railway Construction Corporation(CRCC), one of China's largest heavy construction firms, said Tuesday its first-half-year net profits rose 52.1 percent from one year earlier.

Net profits totaled 3.38 billion yuan (496.16 million U.S. dollars) and earnings per share stood at 0.27 yuan, up 50 percent from the same period last year, the company said in a statement filed with the Shanghai Stock Exchange.

Business revenues grew by 37.71 percent from one year earlier to reach 179.32 billion yuan, the Beijing-based company said.

In spite of the government's measures to regulate the property market, put local governments' financing platforms in order, and restrict the nation's energy-intensive sectors, CRCC still managed to sign new contracts valued at 313.43 billion yuan, up 21.79 percent, said the statement.
