President Xi Jinping on May 28 called for accelerated efforts in building China into a leader in science and technology and achieving sci-tech self-reliance and self-strengthening at higher levels. Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the remarks while addressing a meeting conflating the general assemblies of the members of the Chinese Academy of Sciences and the Chinese Academy of Engineering (CAE), and the national congress of the China Association for Science and Technology (CAST). Sci-tech self-reliance and self-strengthening should always be considered a strategic support for national development, Xi said.

科技攻关要坚持问题导向，奔着最紧急、最紧迫的问题去，从国家急迫需要和长远需求出发。

Scientific and technological research should apply a problem-oriented approach, address the most urgent and pressing problems, and start from the urgent needs and long-term demands of the country.
