The Chinese mainland Wednesday reiterated the importance of upholding the "1992 Consensus" -- which stresses adherence to the one-China principle -- in handling cross-Straits relations.

Yang Yi, spokesman for the State Council's Taiwan Affairs Office, made the remarks at a regular press conference in response to a question concerning the unwillingness of Taiwan's Democratic Progressive Party (DPP) to recognize the "1992 Consensus."

Yang said opposing "Taiwan independence" and adhering to the "1992 Consensus" are the foundations for the mainland and Taiwan to build political mutual trust upon.

They are prerequisites for the improvement and development of cross-Straits relations, he added.

When commenting on reports DPP officials plan to visit the mainland, Yang said all Taiwanese who approve of the peaceful development of cross-Straits ties are welcome to visit the mainland in appropriate capacities.

"We welcome DPP party members visiting in appropriate capacities," he said.

Yang said the process and all of the facts were very clear when reaching the 1992 Consensus.

In November 1992, the Chinese mainland's Association for Relations Across the Taiwan Straits (ARATS) and Taiwan's Straits Exchange Foundation (SEF) held talks in Hong Kong. The organizations reached what is called the "1992 Consensus," under which both sides adhere to the one-China principle.

Founded in 1991 and 1990, respectively, the ARATS and the SEF are authorized by the mainland and Taiwan to handle cross-Strait affairs.
