Hangzhou, the capital of Zhejiang province in east China, lies close to the mouth of the Qiantang River at the western end of the Gulf of Hangzhou. Guangzhou is situated at the heart of the most-populous built-up metropolitan area in mainland China, an area that extends into the neighboring cities of Foshan, Dongguan, and Shenzhen, forming one of the largest urban agglomerations on the planet.
Guangzhou is ranked as an Alpha- Global city. In recent years, there has been a rapidly increasing number of foreign residents and immigrants from Southeast Asia, the Middle East, Eastern Europe, and especially from Africa. This has led to it being dubbed the “Capital of the Third World”. Guangzhou has a comparatively recent history of two centuries related to its importance for foreign trade. Long the only Chinese port accessible to foreign traders, the city fell to the British during the First Opium War. In modern commerce, Guangzhou is best known for its annual Canton Fair, the oldest and largest trade fair in China.
