The two made the pledge yesterday at their fourth meeting when Hu hosted a banquet in Lien's honor.
Lien said that based on the commitments he and Hu made to the people, the two sides will march forward in the direction of pursuing peace and closer cooperation in the future.
Hu said the people on both sides of the strait now anticipate a new chapter in the relations after the situation in Taiwan has undergone dramatic changes.
He expressed the hope that both political parties will seize the new opportunities and environment to continue pushing for closer ties and peaceful developments.
What Hu described as the new situation in Taiwan meant the imminent change of administration on the island as President-elect Ma Ying-jeou of the KMT will soon assume presidency on May 20.
Ma advocates more active interchanges and better business ties with the mainland, including regular direct flights, more Chinese tourists and normalized economic cooperation relationship.
Hu just met Vice President-elect Vincent Siew from Taiwan when both attended a regional economic forum held in China's southern Hainan Province earlier this month.
