China's Vice-Premier Liu He said a number of the country's economic indicators have shown marginal improvement after measures were taken to prevent and control the COVID-19 epidemic.

While China's economic growth still faced downward pressure, the economic trend has shown positive signs, Liu said in a congratulatory letter to the opening of the 12th Lujiazui Forum on Thursday.

Positive results can be seen as companies pick up production. The country's industrial output increased 4.4 percent year-on-year in May and the manufacturing sector grew by 5.2 percent year-on-year.

The country's total fixed asset investment rose by 5.87 percent from a month earlier. Consumption is also showing signs of improvement, represented by the recovery in sales of automobiles and residential housing, Liu said.
