BEIJING, Feb 24 (Reuters) - Urged to restore economic activity by President Xi Jinping, large parts of China relaxed curbs on transport and movement of people on Monday as reported new cases of the coronavirus outside the worst-hit province fell to the lowest in a month.

Figures released by the national health authority on Monday showed 24 out of China's 31 provinces and regions - including Beijing, Shanghai and populous provinces such as Henan and Anhui - reported zero cases of new infections on Feb. 23, the best showing since it began publishing nationwide figures on Jan. 20.

There were just 11 new cases in six other provincial-level jurisdictions, while in Hubei province, the epicentre of the epidemic, the number of new cases fell to 398 from 630 a day earlier.

On Sunday, President Xi hailed the positive trend, and urged businesses to resume work and safeguard jobs. He also told low-risk provinces to restore economic activity and output, while high-risk regions focussed on controlling the epidemic.

Yunnan, Guangdong, Shanxi and Guizhou on Monday lowered their coronavirus emergency response measures from the most serious level, joining the provinces of Gansu and Liaoning in relaxing restrictions on traffic and movement of people.

The coronavirus has infected nearly 77,000 people and killed more than 2,500 in China in one of the most serious public health crises in decades. The pathogen has also spread to other countries such as South Korea, Italy and Iran.

Whether or not China can defeat the epidemic is "a major test of (Communist) Party organisations, party members and cadres of all levels," Xi said, warning officials to avoid complacency.

Hubei remains virtually cut off from the outside world, although the provincial capital of Wuhan, ground zero of the outbreak, said on Monday it will allow people in good health to leave the city for essential reasons.

In the rest of China, factories, businesses and construction sites have already gradually restarted.

Large state-owned enterprises have been told to spearhead a recovery in industry while policymakers roll out measures to support struggling small and medium-sized companies.

China's gross domestic product may slow in the first quarter, possibly easing to 3% growth or even lower, from 6% in the previous quarter - which was already the weakest pace in nearly 30 years, economists estimated.

"The risk is that, with the emphasis on the economy and a differentiation of regions based on the number of new infection cases, the quality of new infection data reported by local governments could be compromised again," Nomura wrote in a research note.
