5G INFRASTRUCTURE

China had built 3.19 million 5G base stations by the end of September in its push to propel the digital and intelligent transformation of the real economy, showed official data Friday.

Each 10,000 Chinese people had 22.6 5G stations by last month, Zhao Zhiguo, spokesperson for the Ministry of Industry and Information Technology, told a press conference.

AI TECHNOLOGY

East China’s Anhui Province has released a three-year action plan, aiming to build itself into an innovation “highland” of the general artificial intelligence (AI) technology industry, said local authorities on Thursday.

The plan focuses on building intelligent computing platforms, promoting the opening up of data resources, developing large models, introducing more application scenarios and attracting more AI enterprises, according to information revealed at a press conference held by the provincial government information office.

CARBON SINK RATE

A new study revealed that Chinese fir, a widely used species for afforestation programs in southern China, has the highest carbon sink rate in its middle age, shedding light on climate change mitigation actions, according to China Science Daily.

Chinese fir, or Cunninghamia lanceolata, is an important native conifer tree in southern China. However, the relationship between the carbon sink capacity of Chinese fir forests and their age had remained unclear until recently.
