BEIJING, May 18 (Xinhuanet) -- The statement issued on Monday by the Taiwan Work Office of the Central Committee of the Communist Party of China (CPC) and the Taiwan Affairs Office of the State Council on current relations across the Taiwan Straits is not an ultimatum, said Director Yu Keli of the Institute of Taiwan Studies of the Chinese Academy of Social Sciences here Tuesday.

    "But this does not mean the Chinese government and people hold a vague stance in safeguarding national sovereignty and territorial integrity," he said.

    Chen Shui-bian, to be inaugurated on May 20, has moved to the brink of "Taiwan independence," so it is necessary to send solemn warning signals to him, said Yu.

    "The current cross-Straits relations are in a crucial time," said Xu Bodong with Beijing Union University, noting Chen's referendum plan for a new "constitution" and implementation of a "Taiwan independence" timetable make the cross-Straits relations more severe.

    The May 17 statement sent warnings to Chen and other "Taiwan independence" separatists, and aimed to let the United States and the international society see clearly the facts that Chen is a troublemaker and threatens cross-Straits peace, he said.

    Only along the seven lines proposed in the statement can the cross-Straits relations hold out a bright prospect of peace, stability and development, he said.

    The statement itself demonstrates the mainland's consistent stance and policies toward Taiwan as well as its sincerity in pushing forward cross-Straits relations, he said.

    It is necessary for the statement to make the cross-Straits situation clear to all the Chinese and the international society, said Guo Zhenyuan with the Institute of International Studies, warning if Taiwan authorities dare to "play with fire," they will "get burnt" themselves. Enditem
