Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.

有分析預測，德國未來應該會將兩國關係定位為「戰略夥伴」與「系統性競爭者」並存的雙重框架：一方面反對保護主義、支持自由貿易，另一方面強化對中國威權擴張的警惕。路透報導指出，從默茨強調「尋找理念相近的夥伴」，顯示德國正從過去與中國無條件接觸轉向有條件、有限度的合作，訪問中國難以帶來「黃金時代」回歸，而是務實的「有限合作」。
