Of course, the premise is that the Ottoman Empire joins Germany as it did in the previous life. In this way, aside from the Suez Canal, East Africa can directly leverage the Persian Gulf and then use the Baghdad railway to transport materials to Germany and Austria-Hungary.
After all, with the Suez Canal under the United Kingdom's control, there are certain risks. However, even so, East Africa has more advantages than the United States, as the U.S. can only choose one route, across the Atlantic Ocean, whereas East Africa has three trade routes. In a more extreme scenario, East Africa can establish a land trade route along the Sahara—Mediterranean coast, although this would be very difficult and lack cost advantages.
This is assuming that history follows its original path and that East African industrial development succeeds, along with a strong navy to protect East Africa's economic interests.
