Yunnan, a favorite tourist destination thanks to its abundant natural resources, has not seen a significant drop in visito rs since Saturday, when a terrorist attack frightened the capital city of Kunming and the entire country.

Ctrip.com, China's largest online travel agency, said that its Yunnan branch has started an emergency mechanism so that tourist guides, drivers and local guides in every city in the province will be on call round-the-clock to work closely with the company's headquarters.

The safety of the company's tourists is closely watched, and no package-tour customers were affected by the attack, the company said. Local hotels and scenic spots have restored order under stricter police surveillance, the company said.

So far, Ctrip has received no requests to cancel trips to Yunnan. It also promised to provide full refunds to anyone who wants to cancel a Yunnan trip.

Qunar.com, another leading online Chinese travel agency, had some hotel reservations canceled after Saturday's attack. All money will be refunded to customers who would like to cancel their hotel reservations, and Qunar will absorb all losses.

The company said the number of tourists heading to Yunnan in the first two months of this year was up slightly year-on-year. Qunar said that it has seen no significant change in the number of tourists.

Zhou Yingfeng, product manager of China Youth Travel Service Shanghai, also has not noticed a sharp drop in the number of tourists heading to Yunnan. But he expected that the number might drop by 20 percent in the short term.

The company had no customers in Kunming when the attack occurred, and no trips to Yunnan were reported.

"It is an emergency. All we can do is to tell our tourists to stay together and avoid going out alone at night," he said.

Besides, most of the company's tourists travel to Yunnan by plane rather than by train, he added.

Sun Liqun, deputy general manager of China International Tourism Service Ltd's domestic destination department, said its tour-group business to Yunnan was normal, although a few individuals canceled their bookings after the terrorist attack.

"We still received some bookings on tour groups to Yunnan province today," Sun told China Daily on Monday.

The travel agency has groups departing to the province every day, and the travelers usually stay in Kunming for two of their six travel days, she added.

Some tourists said they will not change their travel plans because of the attack, but added that they worry about safety in the city.

"I will not go to Yunnan province before the terrorists are arrested, but my travel plan in May will not change," said Wang Dan, a 30-year-old Beijing man.

Wang said he believes that by the time he goes to Yunnan, the province will be safe.

All flights of Lucky Air, one of Yunnan's main carriers, are operating as normal, said a manager from Hainan Airlines, the parent company of Lucky Air.

"The only difference is that the airport has upgraded its security level, and we need to cooperate with them," he said.

Some airlines also will enhance their in-flight security forces in some routes and flights, business insiders said.
