BEJING, Feb. 22 (Xinhuanet) -- Taiwan authority leader's activities to promote the abolishing of Taiwan's "National Unification Council" and "National Unification Guideline" are a dangerous sign of escalation of Taiwan separatists' activities, said a senior Chinese mainland official Wednesday.

    "We'll keep close watch on their activities and prepare to deal with any possible complicated situation at any time," said Chen Yunlin, director of both the Taiwan Work Office of the Communist Party of China Central Committee and the Taiwan Affairs Office of the State Council.

    Chen said if the Taiwan authorities insist on the activities of abolishing of Taiwan's "National Unification Council" and the "National Unification Guideline", the cross-Straits relations would be severely destroyed and the fundamental interests of the Taiwan compatriots will be damaged.

    "We will do our best with our utmost sincerity to maintain the peace and stability across the Taiwan Straits regions. At the sametime, we resolutely oppose any forms of the Taiwan separatists' activities," said Chen. Enditem
