BEIJING, Nov. 26 (Xinhua) -- Adhering to the one-China principle is essential for improving cross-Strait relations and maintaining peace and stability in the Taiwan Strait, a mainland spokesperson said Wednesday.

Peng Qing'en, spokesperson for the Taiwan Affairs Office of the State Council, made the remarks at a regular press briefing when asked to comment on recent statements by Chinese Kuomintang (KMT) Chairperson Cheng Li-wun.

Cheng stated that Taiwan's survival depends on accepting the concept of one China, and questioned why advocating secessionism is allowed while supporting reunification is not on the island.

Peng said that the contrast between upholding and deviating from the one-China principle is clear -- embracing it leads to improved cross-Strait ties and a stable Taiwan Strait, while rejecting it and denying the 1992 Consensus results in rising tensions and harm to the well-being of Taiwan's people.

Noting that "Taiwan independence" secessionism is the greatest threat to peace and stability across the Strait, Peng criticized Taiwan's Democratic Progressive Party (DPP) authorities for suppressing organizations and individuals advocating improved cross-Strait relations.

He called on people across the Strait to uphold the one-China principle and the 1992 Consensus, oppose secessionism and external interference, and work together for peaceful development.

Responding to comments by Taiwan authorities on "one country, two systems," Peng said peaceful reunification under the "one country, two systems" framework is the fundamental policy for resolving the Taiwan question -- and the best approach for achieving national reunification.

"More people in Taiwan now recognize the advantages of this framework and are contributing ideas for a solution tailored to Taiwan," he said.

The specific form of "one country, two systems" in Taiwan would fully account for the island's realities, absorb input from all sectors across the Strait -- and safeguard the interests and sentiments of Taiwan compatriots, Peng said. Enditem
