Hong Kong is known for its expansive skyline and deep natural harbour, and with a land mass of 1,104 km² (426 sq mi) and a population of over seven million people, is one of the most densely populated areas in the world. Hong Kong's economy is characterised by free trade, low taxation and minimum government intervention. It is the world's 7th largest trading economy, with the mainland of China as its most significant trading partner. Hong Kong is also a major service economy, with particularly strong links to mainland China and the rest of the Asia-Pacific region.

The tourism (du lịch Hong Kong) industry is one of the major pillars of the economy of Hong Kong. In 2018, it contributed to around 4.5% of Hong Kong’s GDP and employed around 257 000 persons, accounting for about 6.6% of total employment. In 2019, total visitor arrivals declined by 14.2% over 2018 to 55.91 million, reflecting the impact of the local social incidents.
