Both sides of the Taiwan Straits should ride on the current momentum of warming ties and move forward by addressing existing problems and possible future ones, the Chinese mainland Taiwan affairs chief said yesterday.

"While the cross-Straits relationship faces unprecedented good opportunities, some historical problems also exist and new ones might surface," Wang Yi, director of both the Taiwan Work Office of the Communist Party of China (CPC) Central Committee and the State Council's Taiwan Affairs Office, said at the opening ceremony of a symposium hosted by the Cross-Straits Relations Research Center (CSRRC).

The forum was the first of its kind held after the warming up of relations between the two sides.

"Both sides should solve current disputes cool-headedly and maintain peaceful development," Wang, who has held his appointment as head of Taiwan affairs for a month, said on his first official trip out of Beijing.

His comments come amid a period of rapprochement in cross-Straits relations, where the latest development saw tourist groups arriving in Taiwan on inaugural weekend charter flights from the mainland.

Taiwan has restricted trade and travel with the mainland since 1949, but the island's new leader, Ma Ying-jeou, has helped open doors to warmer ties.

The two sides last month held their first direct talks in a decade and signed agreements to launch the weekend direct charter flights, allowing mainland people to visit the island.

Still, more profound issues, including political and military concerns, are still considered far from being resolved.

Wang said that pioneering work to better relations, based on an objective view of history and a forward-looking attitude, was needed to explore new ways to build on improving relations across the Taiwan Straits.

"The new, positive situation in cross-Straits relations needs new ideas on how to enhance ties through peaceful means," Wang said.

History should be reviewed in a sober way, he added.
