BEIJING - A mainland spokesperson called on Taiwan's opposition Democratic Progressive Party (DPP) to uphold the "1992 consensus" and oppose "Taiwan independence" on Wednesday.

The most important reason for continuous peaceful development of mainland-Taiwan relations since 2008 is that the two sides have adhered to the two principles, said Fan Liqing, spokeswoman for the State Council Taiwan Affairs Office, at a press conference.

Fan was commenting on DPP chair Tsai Ing-wen's remarks that cross-Strait relations must be peaceful and stable and no efforts would be spared (by DPP) to maintain the status quo.

The "1992 consensus" was an agreement reached in 1992 with a core of acknowledging that the Chinese mainland and Taiwan belong to one and the same China.

"Parties or groups won't have obstacles for exchanges with the mainland as long as they recognize the principle," Fan said.

Fan said a series of important achievements have been made based on the 1992 consensus and she hoped the two sides will make joint efforts to maintain the trend.
