China's economic performance in the second half of this year will be significantly better than the first half, said Sheng Songcheng, professor of economics and finance at China Europe International Business School.

Sheng estimated the economic growth rate will reach 1.7 to 3.2 percent year-on-year in the second quarter, and the figure may stay at about 2.1 percent.

Under this condition, the GDP is expected to grow about 3.5 percent in the first half.

"If the growth rate can hit 5.5 percent in the third quarter and 6 percent in the fourth, then the GDP for 2022 is still likely to register 5 percent growth," Sheng said.
