I believe that at this time, this particular statement by President Xi can be seen as an open, official declaration by the Chinese leadership and government that the tech race and tech war between China and the US is now in full steam.

China Telecom Builds First 5G Micro Base Station Using Only Homegrown Tech
It is a major step in the independence of China’s telecoms sector as the global market for 5G micro base station chips is mainly dominated by foreign manufacturers, namely Intel, NXP and Qualcomm.

China's fourth-generation light source facility installs new unit


China's latest high-energy synchrotron radiation light source facility, the High Energy Photon Source (HEPS), on Wednesday installed its first pre-aligned unit inside the storage ring tunnel, kicking off the comprehensive construction of the HEPS accelerator.

A crucial part of the light source for accelerating electrons and generating synchrotron radiation, the storage ring is designed to achieve ultra-low emittance when charging particle beams and thus requires high precision for the construction.

Scientists and engineers at the Institute of High Energy Physics (IHEP) under the Chinese Academy of Sciences (CAS) have adopted an improved hybrid design of magnet systems and made them standard cells that can be pre-assembled in labs at higher precision.

At a circumference of 1,360.4 meters, the storage ring would need 288 of such pre-collimated units, according to Qu Huamin, the chief engineer of the project.

The HEPS accelerator consists of three separate accelerators – the storage ring, the booster and the linear accelerator or linac – which together provide high-quality synchronized light for the beamlines.

Located in Huairou District to the north of suburban Beijing, the facility takes up an area of more than 20 soccer fields. It is China's first fourth-generation synchrotron source and one of only a handful of such facilities in the world.

Started in 2019 and expected to be completed by the end of 2025, the HEPS can provide 60 to 70 beamlines at high brightness with more than 90 experimental stations.

To meet the surging global demand for tests as the COVID-19 pandemic spread last year, one of the leading Chinese biotech firms, BGI, sold test kits to 180 countries and established labs in 18, the lead spy agency says, warning that the genetic data it was collecting could be flowing into Chinese databases.

Although there are no Chinese COVID-19 test labs or kits in the United States yet, China is seeking Americans’ genetic data either by acquiring U.S. genomic sequencing companies or by buying a stake in popular genetic testing companies such as 23andMe. Beijing also has been partnering with U.S. hospital chains to provide cheap genomic sequencing services, according to the agency and a recent report by the U.S.-China Economic and Security Review Commission.

Left unchecked, China’s advances in biotech could lead to drug discoveries capable of undermining the U.S. pharmaceutical industry, the agency said.

“China has amassed the largest genomic holdings of anywhere in the world,” Anna Puglisi, a senior fellow at the Georgetown University’s Center for Security and Emerging Technology, told the Senate Intelligence Committee at a recent hearing. “Understanding what genes do, and so access to that kind of data, both their own and from other places in the world, gives them an advantage in figuring out” how to develop medicines.

Faced with an aging population and expected massive costs associated with future health care needs, China is focusing on precision medicine, or formulating medications tailored for people with specific genetic conditions.

Biological revolution​

But the potential for advances in biotech to yield tailored medicines is only a small part of a much larger set of gains for any country that masters the coming revolution in biology, which experts say could rival or even exceed that of the digital age that yielded computers and the internet.

Synthetic biology, which refers to redesigning biological organisms to have new properties, could lead to as much as 60 percent of the world’s physical inputs being made using biological means, including manufactured silk, leather and non-carbon-based plastics, the McKinsey report said.

‘Carbon efficient’​

Biotech experts often cite the example of Impossible Foods for how biology can revolutionize broad sectors of the economy. The California company’s burgers and sausages are made using altered plant proteins that mimic the taste and feel of beef and pork without downsides of animal proteins, such as high cholesterol or factory farming of cows and pigs.

The plant-based alternatives “are just cheaper and more carbon-efficient” than the animal products, said Jason Kelly, co-founder of Gingko Bioworks, a Boston-based biotech company that programs biological cells to create new strains that are more cost-efficient in developing medicines, food and manufacturing.
