Russian arrivals in Harbin, Heilongjiang province, have climbed sharply since China introduced visa-free entry for ordinary passport holders from Russia in mid-September, according to local authorities and travel platforms. The surge is reshaping tourism patterns in the city and at nearby border crossings.

The Chinese Foreign Ministry policy will be in effect until Sept 14 next year. Under the rule, Russian citizens can stay for up to 30 days for business, tourism, family visits, cultural exchanges, and transit.

One such tourist is 53-year-old Inna Klochko from Vladivostok, who has visited Harbin twice since the policy began on Sept 15.

"I can feel a sense of familiarity with the European-style architecture while strolling along Central Avenue, while I never missed tasting the classic guobaorou (sweet-and-sour pork or beef) at Laochujia Restaurant," Klochko said. "The highlight of my trip, however, is a relaxing soak at the hotel."

For Klochko, applying for a visa used to be a hassle. But under the new policy, she can submit an electronic declaration via an app on her phone. Passing through customs now takes her less than five minutes.

According to online travel platform Ctrip, the number of Russian tourists visiting Harbin has surged by 136 percent year-on-year, with consumption increasing by 150 percent, Harbin Daily reported.
