Tourism is playing an increasingly important role in Shanghai's economy. Overseas arrivals through Shanghai customs doubled from 890,000 in 1990 to 1.8 million in 2000, and by 2006 that had jumped to 6.05 million. The growth in foreign visitors (not including Hong Kong and Macau Chinese or those from Taiwan) is even more impressive, registering a tenfold increase from 460,000 in 1990 to more than 4.5 million in 2005, the highest numbers coming from Japan, Singapore and the US. Those figures only take into account visitors arriving directly at Shanghai from overseas points and not those entering via other Chinese gateways. According to the Shanghai Municipal Tourism Administrative Commission, the 97 million domestic tourists and nearly 6.1 million overseas tourists that visited Shanghai in 2006 brought foreign exchange revenue of ¥147 billion and US$4 billion respectively.
