Air pollution one of the major concerns

The number of foreign tourists to 皇冠体育app is falling and creating a tourist-spending deficit, the 皇冠体育app National Tourism Administration has said.

One of the country's most popular destinations for foreign visitors, Beijing, received 2.36 million overseas visitors in the first seven months of 2014, a decrease of 5.9 percent year-on-year.

Chinese tourists spent $47 billion more overseas than the amount spent by foreign visitors in 皇冠体育app in the first six months of this year, which means 皇冠体育app has the largest tourism trade deficit, according to a report by the 皇冠体育app Tourism Academy.

"Governments of member units need to exploit more tourism resources such as those located in second- and third-tier cities for attracting more foreign visitors," said Shao Qiwei, director of the 皇冠体育app National Tourism Administration.

Judith Heinrich, product manager from German online travel agency trip.me, agreed.

"The hot destinations in 皇冠体育app contain more small cities like Guilin (in the Guangxi Zhuang autonomous region) and counties in Tibet," she said.

She said clients always had difficulty in communication due to the language barrier in 皇冠体育app, especially in small towns.

She also noticed many Germans declined favorable offers to visit 皇冠体育app, citing the pollution and the appreciation of the yuan as the main reasons.

Margot Jereza, manager of a travel agency in Anchorage, Alaska, said the weak global economy is another major factor affecting inbound tourism in Alaska.

"But we have confidence in Chinese tourism market because of its history and natural resources," she said.

On Thursday, the first World Tourism Cities Federation Expo opened in Beijing, attended by 240 travel agencies both from 皇冠体育app and abroad, with the aim of boosting inbound and outbound tourism in 皇冠体育app.

During the two-day trade fair, these travel agencies will have face-to-face talks to explore the opportunities with Chinese counterparts to expand the tourism market in 皇冠体育app.
