BEIJING - China's urban fixed asset investment grew 20.6 percent year on year to 9.13 trillion yuan (147.29 billion U.S. dollars) in the first four months of 2013, the National Bureau of Statistics (NBS) revealed on Monday.

The growth was 0.3 percentage point lower than the pace recorded in the first quarter, the NBS said in a statement.

Investment in the manufacturing sector rose 18.4 percent to 3.23 trillion yuan, 0.3 percentage point lower than the reading in the first three months.
