Top political advisor Yu Zhengshengon Monday urged Taiwan's social organizations to oppose Taiwan independence and help integrate the two sides across Taiwan Strait.

Yu, chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), made the remarks when meeting with delegates to a forum attended by social organizations of Taiwan compatriots.

Yu said cross-Strait ties are facing a serious challenge as the Taiwan authority refuses to recognize the 1992 Consensus.

He urged social organizations of Taiwan compatriots to safeguard the 1992 Consensus, the political foundation for peaceful cross-Strait development, and resolutely oppose Taiwan independence in any form.

The top political advisor also called for promoting the economic and social integration of the two sides.

Yu welcomed more Taiwan youngsters to the Chinese mainland for exchanges to deepen their understanding of the mainland.
