China's exchange rate is approaching an equilibrium level, Xinhua News Agency reported late Friday, citing an adviser to China's central bank.

Due to stronger currency, the trade surplus of China has decreased notably over the last few years.

The trade surplus is likely to fall further this year, to 1 percent as share of the gross domestic product, suggesting that the reform of the yuan's exchange rate mechanism has been successful, Li Daokui, an academic adviser to the People's Bank of China said.

Li said people in the international community even do not know the latest figures and their minds are filled with the old figures about China's trade surplus.
