The trade route between China and British India passed through the Malacca Strait, and with the growing trade with China, that route would become increasingly important. However, the Dutch had tight control over the trade in the region and intended to enforce the exclusive rights of its company ships to trade, and that trade should be conducted at its entrepot Batavia. British trading ships were heavily taxed at Dutch ports, stifling British trade in the region.

The Dutch had been stifling British trade in the region by prohibiting the British from operating in Dutch-controlled ports or by subjecting them to a high tariff. Raffles hoped to challenge the Dutch by establishing a new port along the Straits of Malacca, the main ship passageway for the India-China trade. He needed a third port since the British only had the ports of Penang and Bencoolen. The port had to be strategically located along the main trade route between India and China and in the middle of the Malay Archipelago. He convinced Lord Hastings, the Governor-General of India and his superior at the British East India Company, to fund an expedition to seek a new British base in the region.
