President Xi Jinping said the country must resolve issues in key technological fields from the bottom up, state media reported, as the country deals with a growing number of mainly US export controls on advanced technology.

Xi said on Tuesday during a study session of the 24-person Politburo – one of the top decision-making bodies of the Communist Party – that the nation needed to strengthen basic research in science and technology if it is to achieve self-reliance and become a global tech power, news agency Xinhua reported.

"To cope with international science and technology competition, achieve a high level of self-reliance and self-improvement ... we urgently need to strengthen basic research and solve key technology problems from the source," Xinhua quoted Xi as saying.

The call comes as the mainland faces growing headwind in its years-long effort to close the gap with the United States and its allies in advanced semiconductor technology.

In January, Japan and the Netherlands agreed to comply with export restrictions against the mainland's chip sector that the US government had announced in October 2022, media reported.

Initial US sanctions took aim at mainland purchases of advanced artificial intelligence computing chips, as well as equipment that chip factories could use to produce leading-edge computing chips.

Xi also on Tuesday said it was necessary to grow the nation's pool of top-notch tech talent, Xinhua reported, echoing a speech in 2021 where he said that by 2035 China "should rank among the leading countries in the world with respect to our strategic and technological strength and our army of high-quality talent".
