Final answer:
The king of Egypt faces diplomatic and economic issues related to trade routes, banditry, and declining influence in the region.
Step-by-step explanation:
The particular diplomatic and economic issues faced by the king of Egypt are related to maintaining control over trade routes, dealing with banditry and instability in commercial centers, and losing influence in the region. Toward the end of the New Kingdom era, Egypt's ability to control trade in Canaan and Syria declined, leading to increased instability and challenges in maintaining economic stability. These issues impacted Egypt's diplomatic relationships with other nations and its ability to maintain economic prosperity.
