The number of travelers from the Chinese mainland to Taiwan rose during the May Day break and visits to Hong Kong fell.

The tourism authority of Taiwan said 32,000 individual trips were made from the mainland to Taiwan, a 33 percent year-on-year rise. There were 9,864 visitors who were not part of tours. That's more than double compared with the same period last year.

The number of mainland travelers to Hong Kong fell for the first time since the special administrative region opened self-guided tours to mainland residents in 2003.

"The decline of Hong Kong is not the only reason for the rise of Taiwan," Jiang Zhiduan, director of the Taiwan Strait Tourism Association's Beijing's office, said.

It is a market choice, he added.

Because of demand, Taiwan increased its quota for independent mainland tourists to the island from 3,000 to 4,000 a day from April 16.

A rise to 5,000 will be considered.

Mainland travel agencies also see business opportunities and are investing more into the market.

"It is expected that almost 100,000 self-guided travelers will visit Taiwan through Ctrip.com this year," said Xu Zhiyun, general manager of the outbound tourism department of Ctrip.com International Ltd, a Chinese online travel agent.

During the May Day holiday, Ctrip's sales of products to Taiwan grew 100 percent compared with the same period last year, he said.

"Taiwan is already one of the most popular destinations among mainland travelers," Xu said.
