On July 4 Ukrainian President Zelenskiy said he spoke by phone with US President Trump. They exchanged views on frontline developments in the Russia-Ukraine conflict, diplomatic progress and the realistic prospects for a ceasefire, and agreed to hold a face-to-face meeting during the NATO summit in Ankara to continue discussions.

At the Yabuli Forum Innovation Annual Conference in Shanghai (July 3-4), Yushu Technology co‑founder Chen Li said the company has completed in‑house R&D and production of core components and underlying architecture, enabling end‑to‑end manufacture of quadruped and humanoid robots, robotic arms, pump bodies and dexterous hands. He said joint‑motor core technology is fully self‑developed and the upstream only involves basic raw materials such as copper wire and magnets, with the supply chain fully autonomous and controllable. Chen added Yushu’s self‑developed stack delivers leading cost‑performance, reliability, stability and consistency, and the firm continues to invest in control, perception, navigation and AI algorithm R&D, with multiple patent filings.
