China has seen a sharp rise in non-taxation income in the first half of the year, compared with a slowing pace of tax revenue, the top finance official said on Wednesday.

Xie Xuren, minister of finance, told lawmakers in a report on the budget execution in the first six months of the year that the central government has received more than 230 billion yuan ($36.1 billion) in the first six months, a 49.3 percent increase year-on-year.

The figure strikes a stark contrast to tax revenue income growth in the same period, which stood at 7.6 percent.

In particular, two major taxes for the central revenues, domestic value-added tax and domestic consumption tax increased 6.4 percent and 11.7 percent, respectively, the minister said.

Xie said that non-taxation income increased considerably due to the oil prices surge and other factors.

Non-taxation income include administrative fees, fines and other incomes, according to the Ministry of Finance's website.
