The Chinese mainland's Taiwan affairs chief on Thursday called for stronger cooperation with Taiwan on high-tech, finance and emerging industries.

Wang Yi, director of the Taiwan Work Office of the Communist Party of China (CPC) Central Committee, made the remarks at the opening ceremony of Jiangsu-Taiwan Week in Nanjing, capital of Jiangsu Province.

Wang said the mainland and Taiwan had much work to do to promote the normalization and liberalization of cross-Straits economic relations after the landmark cross-Straits Economic Cooperation Framework Agreement (ECFA) took effect earlier this month.

Both sides should endeavor to make more preparations for the "early harvest" program of goods trade agreed in the ECFA, Wang said.

According to the early harvest program, an integral part of the ECFA, the duties on 539 Taiwan goods and 267 mainland products will be reduced to zero in three phases within two years from Jan. 1, 2011.

The Taiwan products involved include farm produce, chemicals, machinery, textiles and auto parts.

Wang said authorities on both sides should make more efforts to implement the commitment on the early harvest program for the service sector as soon as possible.

The official suggested that mainland and Taiwan authorities should establish a special committee for cross-Straits economic cooperation, through which the both sides could negotiate on the ECFA's implementation and discussions to deal with new problems during the economic exchange.

Wang said that exchange visits by mainland and Taiwan delegations, which were attracting more organizations and individuals, had become a major activity in cross-Straits contacts.

The mainland would continue to send delegations to Taiwan and adapt visits to Taiwan people's needs, and the mainland welcomed more Taiwan delegations.
