The United Nations World Tourism Organization has confirmed that 2012 saw China become the top tourist source market in the world. In 2012 Chinese expenditure on travel abroad climbed to 102 billion U.S. dollars, culminating a period in which it has been the most rapidly growing source market for tourism in the world. Since the turn of the century, there has been over an eightfold increase in the number of overseas trips made by Chinese travelers from 10 million who travelled to other countries in 2000, up to 83 million who went abroad in 2012.
