China has accused the US of violating a 90-day trade truce by imposing new restrictions, including AI chip export controls and revoking student visas. President Trump claims China is at fault, escalating tensions. Amid stalled negotiations, Trump is expected to speak with Chinese President Xi Jinping this week, potentially including German Chancellor Friedrich Merz in the conversation. The urgency is palpable as the US administration seeks trade proposals by June 4, but only one tentative agreement has been reached with the UK. Meanwhile, China's factory activity has shrunk for the first time in eight months, indicating the impact of US tariffs.
