China’s AI research is booming. Where is it headed?

In China, the realm of artificial intelligence (AI) is experiencing a rapid growth and transformation. Computer scientist Lu Yi, who will soon graduate from a top university, faced a dilemma when deciding whether to pursue higher studies in the United States or stay in China. While the US offers higher salaries, advanced hardware, and premier AI laboratories, Lu believes that the gap between China and the US in AI research is rapidly closing.

China now trains more AI researchers than any other country, boasting 51,000 active AI researchers, compared to just 14,000 in the United States. Many of these Chinese researchers are still early in their careers, with fewer established superstars compared to the US. The trend is evident in the prestigious NeurIPS conference, where 57% of authors have Chinese undergraduate degrees, up from 46% three years ago.

However, the United States still attracts many graduate-level students, securing around one-fifth of those undergraduates.

Despite this, the US is becoming less appealing to foreign researchers due to an increasingly stringent visa system. Lu has personally witnessed friends face rejection or delays in their visa applications. Additionally, the US is experiencing a drop in the number of Chinese students studying mathematics or computer science, with a 20% decrease over the past five years. This trend is attributed to visa troubles and growing animosity among peers due to the US-China geopolitical rivalry.

China's AI ecosystem is distinct from that of Silicon Valley in the US. The boundaries between academia and industry are more fluid in China, but access to computing resources is more limited. This presents both opportunities and challenges for Chinese firms, who have been accused of copying US advances but have also developed techniques to make more efficient models. Chinese AI research is gaining influence, as evidenced by the dominance of Chinese researchers in AI-related academic papers, citations, and patents.
