China's stalled economy is starting up much earlier than Europe and the United States, which are easing restrictions gradually as they struggle with high reported infections and deaths from COVID-19, a disease caused by the novel coronavirus.

Baidu forecast current-quarter revenue between 25.0 billion yuan (3.52 billion U.S. dollars) and 27.3 billion yuan, while analysts on average had expected 25.55 billion yuan.

The company said daily active users for Baidu App surged by 28 percent in March to hit the 222 million mark.

"This performance is encouraging, as it shows that the worst stretch is likely over for Chinese internet companies as the economy slowly gets back to its feet and the digital ad market revives," said Haris Anwar, senior analyst at financial markets platform Investing.com.

Revenue from Baidu's online marketing services business, which includes search, news feeds and video apps and is a major contributor to overall sales, tumbled by 19 percent to 14.24 billion yuan in the first quarter ended March 31.

Total revenue declined about seven percent to 22.55 billion yuan, but beat estimate of 21.93 billion yuan.
