US-China trade talks in London this week aim to address new disputes threatening a fragile tariff truce. Recent disagreements include US restrictions on Chinese tech company Huawei's AI chips, export controls on rare earth minerals crucial for various industries, and a US plan to revoke visas for some Chinese students. While China indicated it's addressing rare earth concerns, the US accuses China of violating their Geneva agreement. Technology and export controls remain major sticking points.
