The 1992 Consensus defines the nature of the relationship between both sides of the Taiwan Straits and is the key to maintaining peace and stability across the Straits, said a mainland spokesperson on Wednesday.

Ma Xiaoguang, spokesperson with the State Council Taiwan Affairs Office, said that the 1992 Consensus, which sets out the one-China principle, is undeniable when responding to a question about the refusal by the island's current administration to acknowledge the 1992 Consensus.

"Compatriots on both sides of the Straits should stay vigilant to any attempt of denying the Consensus," said Ma.
