The Maritime Silk Road

Long before caravans gave the Silk Road its fame, ships were carrying more goods between Asia and the West by sea, and for longer. The Maritime Silk Road was the chain of monsoon routes that linked the ports of southern China with Southeast Asia, India, the Persian Gulf, the Red Sea, and the coast of East Africa. Its cargoes were heavier and humbler than silk alone: porcelain by the shipload, pepper, cloves, incense, cotton cloth, horses, and timber. Today the name carries a second meaning. Since 2013 it has been China's label for the sea leg of the Belt and Road Initiative, a program of ports and shipping links that Beijing presents as shared development and that critics see as strategic reach.

The historic route left Guangzhou, Quanzhou, or Ningbo and crossed the South China Sea along the coast of Vietnam to the Strait of Malacca or the Sunda Strait, where kingdoms such as Srivijaya grew rich on the traffic. Ships then crossed the Bay of Bengal to Sri Lanka and the Malabar Coast of India, and the Arabian Sea to the Gulf ports of Siraf, Hormuz, and Basra or to Aden and the Red Sea for Egypt. Other routes ran down the Swahili coast to Mombasa and Kilwa. Everything moved to the rhythm of the monsoon, which blows from the northeast in winter and the southwest in summer, so merchants often waited months in foreign ports for the winds to turn, and diaspora communities grew around them.

The Belitung wreck, an Arab-style ship lost off Indonesia in the ninth century with some 60,000 Chinese ceramics, shows the trade's scale under the Tang. Quanzhou, inscribed by UNESCO in 2021, was one of the world's great ports under the Song and Yuan. Zheng He's Ming fleets sailed as far as East Africa between 1405 and 1433. Xi Jinping announced the 21st-Century Maritime Silk Road in a speech to Indonesia's parliament in October 2013. Chinese firms have since built, financed, or taken stakes in ports including Piraeus, Gwadar, Hambantota, leased for 99 years in 2017, and Chancay in Peru. Beijing describes the program as connectivity and development, while U.S. and Indian officials cite debt and possible military use, claims China rejects. Researchers at Griffith University counted a record $213.5 billion in Belt and Road deals in 2025.
