The U.S. is preparing to tell dozens of countries they must pick sides in the artificial intelligence race with China, warning they will be excluded from a U.S.-led AI coalition if ?they also sign up for Beijing¡¯s competing framework, according to a U.S. official and an internal draft reviewed by reporters.

Washington last year launched ?the Pax ?Silica initiative aimed at securing supply chains for AI models, semiconductors and critical minerals, amid a fierce technology rivalry ?with Beijing.

About two dozen countries have joined, including Kazakhstan, a key potential source of critical minerals that has also joined China¡¯s coalition, as well as close U.S. allies such as Japan, Australia and South Korea.
