China 'key source' for world's tourist cities

While the world adjusts to the new world order in global trade, tourism is booming and China is in the driver's seat.

Data released by Tourism Economics, an Oxford Economics company, says 630 million foreign visitors are expected to visit the world's top 300 cities in 2019, an increase of 28 million from last year.

These cities will account for almost 50 percent of global international visitor arrivals in 2019, while being home to just under 20 percent of the world's population.
