China’s annual fiscal revenue growth slowed to 3.9 percent in the first quarter from 8.6 percent in 2014, official data showed, as persistent economic weakness dampened tax collection and other government incomes. Revenues totaled 3.64 trillion yuan ($587.67 billion) in the first quarter, data from the Finance Ministry showed on Thursday. In March, China’s fiscal revenues totaled 1.069 trillion yuan, up 5.8 percent from a year earlier, the ministry said.
