The mainland office responsible for cross-Straits relations has urged Taiwan to improve safety across its whole tourist sector and to take measures to ensure the safety of mainland travelers.

According to local media reports, the island's transportation authority will raise the daily quota for mainlanders from 5,000 to 6,000 and allow them to stay for 30 days rather than 15.

The move comes after statistics showed a drop in the number of mainland tourists visiting over the Spring Festival holiday.

Taiwan ranked ninth on online travel agency Ctrip's annual list of the most popular destinations for outbound tourists over the holiday, down from fifth last year.

Data from Taiwan's Travel Agent Association also showed the number of mainland visitors had dropped by 20 percent during Spring Festival compared with last year.

However, on Wednesday, An Fengshan, a spokesman for the State Council Taiwan Affairs Office in Beijing, said the reason for the decline was "quite clear" and would only be reversed through improved cross-Straits relations.

"Other solutions are a move in the wrong direction and will not succeed," he said.

Zhu Songling, a professor at Beijing Union University's Institute of Taiwan Studies, said the decline in mainland tourists has affected Taiwan's tourism industry and its economy.

Relations between the mainland and Taiwan have been tense since Tsai Ing-wen took office as the island's new leader on May 20.
