TOKYO -- China is overtaking the U.S. in artificial intelligence research, setting off alarm bells on the other side of the Pacific as the world's two largest economies jockey for AI supremacy.
In 2020, China topped the U.S. for the first time in terms of the number of times an academic article on AI is cited by others, a measure of the quality of a study. Until recently, the U.S. had been far ahead of other countries in AI research.
