One year after the Winter Olympics, Sochi urged its residents to study Chinese, ready to attract more tourists from China.

Sochi, a Russian city on the coast of the Black Sea, boasts its charming seaside resorts and marvelous mountain skiing landscape. And more, it hosted the 2014 Winter Olympics.

Before the 2014 Winter Olympics kicked off in February, the city urged its residents to study English to create a friendly environment for the games. But today, almost one year after the Winter Olympics, it called on them to study Chinese, ready to attract more tourists from China.

Sochi Mayor Anatoly Pakhomov recently told a Chinese business delegation that hotel managers in Sochi who are expecting Chinese tourists would need their working staff to speak Chinese.

China has been more and more important to Russia on cooperation in the air transportation sector, said Leonid Sergeev, chief executive officer (CEO) of Russia's Bazel Aero airline.

China Southern Airlines, Air China and many other Chinese airlines are currently considering opening direct flights to Sochi, said Sergeev.

Chinese tourists turned their eyes to Sochi because the city has effectively reinvented itself during preparation for the Olympic games. Thanks to the Olympics, Sochi improved or built infrastructure like children playgrounds, swimming pools, tennis courts and, what is the most important, modern residential buildings.

The full transformation of Sochi from an Olympic host city to a "normal" resort city will take about five to seven years, said Andrei Elinson, the managing director of the "Imereti Valley" resort project in Sochi.

In 2014, over 3 million people visited the city, a 28 percent increase year one year, said Lilia Burangulova, a representative of Sochi International Airport. The city was considering giving permission to foreign visitors for a three-day visa-free stay if they choose the city as a port of entry.

Last year, the sharp depreciation of the Russian ruble has played a positive role for the development of the country's tourism industry, since services like hotel accommodations became more affordable for foreign visitors.

"We hope to attract more Chinese tourists, especially when Russian tourism has more price advantages considering the depreciation of the ruble," said Shevchenko Ruslan, a project manager of the "Imereti Valley", where the Olympic village was once located.

Ruslan said that the valley has included many Chinese elements, such as Taichi classes and Chinese-style health care services, as more and more Russians are getting interested in China and Chinese culture.

Natalia Likhobabina, the sales director of Rodina Hotel in Sochi, believes the city needs long-term cooperation with China.

"Chinese people still have a limited knowledge about our city. China and Russia need to work together in various spheres and communicate more. Still, the situation may take years to get better," Likhobabina said.

One of such efforts was made at the end of last year, when a Chinese delegation consisting of 30 tourism agency representatives visited Sochi. Sochi, in return, has sent its tourism professionals to several Chinese cities.

"I found the most attractive things in Sochi are the thermal springs and skiing. The city is also a great resort for health tourism," said Liu Weizhi, member of the Chinese delegation.

Nevertheless, Liu also pointed out some problems that might scare off potential Chinese visitors, like the poor city transit system and generally high costs of services. As Sochi sprawls for 145 km along the shores of the Black Sea, the trip through the whole city took too much time, Liu said.

Still, Sochi Mayor Pakhomov hopes that the city will become Russia's "third capital" after Moscow and St. Petersburg.

He passionately assured that Chinese tourists would prefer Sochi to the European resorts, adding that China's interest in Sochi has been growing rapidly.

The mayor said that some 600,000 Chinese visited Russia last year, and promised that Sochi is capable of accommodating 2 million Chinese tourists a year.

To support that, Sochi plans to open direct flights to China's capital city of Beijing and Changzhou city in east China's Jiangsu province in June, 2015.
