Abstract
The China Initiative, launched by the United States in 2018, has significantly reshaped scientific collaboration patterns between China and the U.S., particularly in the field of artificial intelligence (AI). This study examines the evolving dynamics of Sino-US AI research collaboration, focusing on the post-2018 period marked by geopolitical tensions, by using a comprehensive dataset from DBLP and DBLP-Citation-Network-v16. Our analysis reveals that (1) collaboration between the two nations shows a reversed U-shape where the peak is 2019, (2) China shifts its international collaboration to the EU and the U.S. strengthens ties with Canada, and (3) the AI subfield computer vision experiences the most pronounced impact under the China Initiative, because new collaboration in this field dramatically decreases and existing collaboration is largely suspended, which highlights its vulnerability to geopolitical disruptions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
