TAIPEI - More than 70 percent Taiwanese are satisfied with the current direct flight and shipping services across the Taiwan Straits, according to a poll released Tuesday by Taiwan's mainland affairs department.

The poll shows that 72 percent of the respondents believe that mainland tourists to the island are conducive to Taiwan economy.

More than 48 percent of the surveyed said the current scale of cross-Straits exchanges is "appropriate", whereas 25.7 percent consider it "too fast" and 12.9 percent said that it is "too slow ", the poll indicates.

Starting from June, 558 direct flights are operated each week between 50 destinations across the Straits. Before that, there were 370 flights per week, the mainland affairs department said.

More than 13.84 million passengers took cross-Straits flights between September 2009 and November 2011, according to Taiwan's civil aviation department.
