Nationwide, just 52,000 people arrived to mainland China from overseas on trips organized by travel agencies during the first quarter, the latest period for which national data is available, compared with 3.7 million in the first quarter of 2019. As in past years, nearly half of the visitors came from the self-ruled island of Taiwan and the Chinese territories of Hong Kong and Macau, rather than farther-away places like the U.S. or Europe.

“The number of visitors from Europe, America, Japan and Korea are all dropping, substantially,” said Xiao Qianhui, a director with the semiofficial China Tourism Association in a speech in May.
