THE CITY OF HONG KONG
The territory of Hong Kong covers approximately 1,000 square kilometres and comprises Hong Kong island, the Kowloon Peninsula, the New Territories, and around 400 outlying islands. It has a population of more than six million people, 98% of whom are Chinese. Cantonese is the major language while English is widely used. During April, the weather is warm, sunny and humid with average temperatures ranging from 20 to 25 degree celsius.

Hong Kong is located on the southern coast of China and is served by several airlines including Air Canada, Cathay Pacific, British Airways, Virgin, Northwest, United Airlines, Delta Airlines, Air France, and Japan Airlines.
 
VISAS
Please contact your local Chinese Embassy for information regarding visas for Hong Kong and Mainland China. No visas are required to enter Hong Kong for British, American and Canadian passport holders. However, a visa will be required for any trips to Mainland China. Arrangements can generally be made for the issue of these visas in Hong Kong.
 
GETTING AROUND
Hong Kong has a good, fast public transport system. Also taxis are cheap, reliable and plentiful.

The Conference meeting place in the Academic Exchange Building (AEB) of City University is well located, just a few minutes walk to the Mass Transit Railway (MTR) and Kowloon-Canton Railway (KCR) interchange station in Kowloon Tong. From here it is about 20 minutes by the MTR (south) to Central Hong Kong or 45 minutes (north) by the KCR to mainland China. The AEB is also a short walking distance from campus restaurants.

We recommend taking a taxi from the airport to the Royal Park Hotel, the Royal Plaza Hotel, the Hong Kong Sports Institute, and the City University accommodation. The cost should be between US$10 and US$15.
