BEIJING -- A Chinese mainland spokesperson on Thursday criticized Taiwan's Democratic Progressive Party (DPP) authority for its sinister intention of deliberately obstructing exchanges of compatriots across the Taiwan Straits and damaging cross-Straits relations.

People on both sides of the Straits have expressed a strong willingness to strengthen exchanges and cooperation, and jointly promote integrated development at the 14th Straits Forum, said Zhu Fenglian, a spokesperson for the Taiwan Affairs Office of the State Council.

The one-China principle is the political foundation of cross-Straits relations, and the 1992 Consensus, which embodies the one-China principle, is the key to ensuring the peaceful development of cross-Straits relations, Zhu said.

"We resolutely oppose any words and deeds that distort, reject and smear the 1992 Consensus and its core essence," Zhu said.

Zhu pointed out that the collusion of the "Taiwan independence" forces and the external forces is the root cause of the current strained and volatile situation across the Straits.

"No one should underestimate our resolve, will and ability to defend national sovereignty and territorial integrity," Zhu said.
