BEIJING, Nov. 7 (Xinhua) -- A senior Chinese official on Monday called on Taiwan entrepreneurs doing businesses on the mainland to promote cross-Strait economic relations for the well-being of people on both sides.

Jia Qinglin, a member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee, made the remarks at a technology seminar set up to help Taiwanese delegates promote their products in Beijing.

Jia said there have been -- and continue to be -- both opportunities and challenges for economic cooperation since the mainland and Taiwan deepened economic ties in May 2008.

The mainland's 12th Five-Year Plan, which started this year, and Taiwan's "Golden Decade" economic blueprint have provided more opportunities for the two sides, said Jia, who is also chairman of the National Committee of the Chinese People's Political Consultative Conference, China's top political advisory body.

At the same time, both the mainland and Taiwan need to upgrade and transform their industries amid international economic changes, Jia said, urging people on both sides to cooperate to improve the competitiveness of China as a nation.

Jia also stressed that the 1992 Consensus is fundamental to cross-Strait relations.
