People's Daily, China

China has performed outstandingly well in scientific research and technological innovation among the G20 countries, and the country's scientific and technological strength in the field of AI is seeing rapid growth, second only to the US, a report shows. According to the report, in terms of the overall scientific and technological strength of AI, the US ranks first among the G20 countries followed by China, whose technological strength in AI has increased significantly, especially in the past five years. China has performed outstandingly well in the first three fields among the four branches of AI--machine learning, natural language processing, computer vision, and speech processing. But while the output of the country's scientific research has surpassed that of the US, improvements are needed in terms of the quality of the output. The report focuses on the scale of research output, academic impact, and international cooperation among the G20 countries, as an indication of China's position in the competitive landscape, as well as the challenges it faces.
