trade that existed in Southeast Asia at that time: the Chinese network, which linked Southeast Asia with the southern Chinese ports of Fujian and Guangdong; the Southeast Asian network, which linked the islands of the Indonesian archipelago; and the European and Indian Ocean network, which linked Singapore to the markets of Europe and the Indian Ocean littoral. These networks were complementary, and positioned Singapore as the transshipment point of regional and international trade. By the 1830s, Singapore had overtaken Batavia (now Jakarta) as the centre of the Chinese junk trade, and also become the centre of English country trade, in Southeast Asia. This was because Southeast Asian traders preferred the free port of Singapore to other major regional ports which had cumbersome restrictions. Singapore had also supplanted Tanjung Pinang as the export gateway for the gambier and pepper industry of the Riau–Lingga Archipelago by the 1830s, and South Johor by the 1840s. It had also become the centre of the Teochew trade in marine produce and rice. As the volume of its maritime trade increased in the 19th century, Singapore became a key port of call for sailing and steam vessels in their passage along Asian sea routes. From the 1840s, Singapore became an important coaling station for steam shipping networks that were beginning to form. Towards the late 19th century, Singapore became a staple port servicing the geographical hinterland of the Malay Peninsula. Following the institution of the British Forward Movement, Singapore became the administrative capital of British Malaya. Roads and railways were developed to transport primary materials such as crude oil, rubber and tin from the Malay Peninsula to Singapore to be processed into staple products, and then shipped to Britain and other international markets. During the colonial period, this was the most important role of the port of Singapore. 1963–2021 Singapore ceased to be part of the British Empire when it merged with Malaysia in 1963. Singapore lost its hinterland and was no longer the administrative or economic capital of the Malay Peninsula. The processing in Singapore of raw materials extracted in the Peninsula was drastically reduced due to the absence of a common market between Singapore and the Peninsular states. Since Singapore's full independence in 1965, it has had to compete with other ports in the region to attract shipping and trade at its port. It has done so by developing an export-oriented economy based on
