The main route of the western regions of the Maritime Silk Road directly crosses the Indian Ocean from the northern tip of Sumatra (or through the Sunda Strait) to Sri Lanka, southern India and Bangladesh, and the Maldives. It branches from here into routes through the Arabian Sea entering the Gulf of Oman (into the Persian Gulf), and the Gulf of Aden (into the Red Sea). Secondary routes also pass through the coastlines of the Bay of Bengal, the Arabian Sea, and southwards along the coast of East Africa to Zanzibar, the Comoros, Madagascar, and the Seychelles.
