Amazon is shutting down its AI research lab in Shanghai, marking another step in its gradual withdrawal from China. The move comes amid continuing US-China trade tensions and a broader trend of American tech companies reassessing their presence in the country.

The company said the decision was part of a global streamlining effort rather than a response to AI concerns.

A spokesperson for AWS said the company had reviewed its organisational priorities and decided to cut some roles across certain teams. The exact number of job losses has not been confirmed.

Before Amazon's confirmation, one of the lab's senior researchers noted on WeChat that the Shanghai site was the final overseas AWS AI research lab and attributed its closure to shifts in US-China strategy.

The team had built a successful open-source graph neural network framework known as DGL, which reportedly brought in nearly$1 billion in revenue for Amazon's e-commerce arm.

Amazon has been reducing its footprint in China for several years. It closed its domestic online marketplace in 2019, halted Kindle sales in 2022, and recently laid off AWS staff in the US.

Other tech giants including IBM and Microsoft have also shut down China-based research units this year, while some Chinese AI firms are now relocating operations abroad instead of remaining in a volatile domestic environment.
