In 1863 the American concession—land fronting the Huangpu River to the north-east of Soochow Creek (Suzhou Creek)—officially joined the British Settlement (stretching from Yang-ching-pang Creek to Suzhou Creek) to become the Shanghai International Settlement. The French concession remained independent and the Chinese retained control over the original walled city and the area surrounding the foreign enclaves. This would later result in sometimes absurd administrative outcomes, such as needing three drivers' licenses to travel through the complete city.
