BEIJING, May 27 -- A Chinese mainland Taiwan Affairs Office spokesperson on Wednesday asked the Taiwan opposition Democratic Progressive Party (DPP) to clarify its stance on cross-Strait ties while highlighting the "one China" principle.

Commenting on recent calls by the DPP to maintain the "status quo" with the Chinese mainland, State Council Taiwan Affairs Office spokesperson Fan Liqing told a press conference that the DPP should clarify its definition of the term.

"The Taiwan public wants to know exactly what the DPP means when it uses the term 'status quo'. That's a question it must answer loud and clear," she said.

The spokesperson said that although the Chinese mainland and Taiwan had been separate since 1949, the fact that the two sides belong to one China has not changed. She underscored that the country's sovereignty and territorial integrity must not be compromised.

Cross-Strait ties have witnessed peaceful development since 2008 on the basis of the 1992 consensus, the core of which is the acknowledgment that the Chinese mainland and Taiwan belong to one and the same China, she continued.

"That is the real status quo of cross-Strait ties," Fan said.
