BEIJING, March 4 (Xinhua) -- Chinese President Xi Jinping has said science and technology are mankind's most powerful weapon against diseases.

Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, has also stressed the pivotal role of science and technology in eventually defeating the novel coronavirus disease (COVID-19) epidemic.

Since the outbreak, he has made a series of instructions on advancing related scientific research.

The following is a timeline of the instructions that have been made public.

JANUARY 25

Xi chaired a meeting of the Standing Committee of the Political Bureau of the CPC Central Committee on the COVID-19 prevention and control, which called for speeding up the research and development of drugs and vaccines.

JANUARY 29

In an instruction made public on that day, Xi called on military research institutions to step up scientific research to contribute to the fight against the epidemic.

FEBRUARY 3

At a meeting of the Standing Committee of the Political Bureau of the CPC Central Committee, Xi urged scientific efforts in virus source tracing. He also called for identifying the source of infection and the transmission routes at an earlier date, closely tracking the mutation of the virus and promptly developing strategies and measures on its prevention and control.

FEBRUARY 10

During an inspection in Beijing, Xi required accelerating the selection, research and development of drugs with good clinical effects.

He also called on universities, research institutes and enterprises to redouble efforts in the research and development of reagents, vaccines and drugs for early breakthroughs.

FEBRUARY 12

Xi chaired a meeting of the Standing Committee of the Political Bureau of the CPC Central Committee which urged greater efforts in the research and development of drugs and vaccines.

FEBRUARY 14

Addressing a meeting of the central committee for deepening overall reform, Xi encouraged the use of digital technologies such as big data, artificial intelligence, cloud computing to support the epidemic surveillance and analysis, virus source tracing, epidemic prevention and control, disease treatment, and allocation of resources.

MARCH 2

During an inspection to two institutes in Beijing, Xi called for speeding up vaccine research and development while closely tracking the progress of related research overseas to strive for early clinical trial and application of vaccines.

Xi stressed the importance of coordinating research on virus source tracing and transmission routes and evaluating whether some suspected animals are intermediate hosts.

Xi also called on countries to share research data and jointly work out response strategies to contribute to building a community with a shared future for humanity. ■
