TAIPEI, Aug. 17 (Xinhua) -- Companies from the Chinese mainland manufacturing hub of Guangdong signed deals worth 2.99 billion U.S. dollars with Taiwanese counterparts here Tuesday at the start of the Taiwan-Guangdong Week trade event.

The 31 deals involve Guangdong companies buying electronic products, raw industrial materials and farm produce from Taiwan and investing in battery- and electronic device-producing projects on the island.

The two sides are expected to reach deals worth 6.7 billion U.S. dollars during the week, said Liang Yaoguang, head of Guangdong's Foreign Trade and Economic Cooperation Department, at the opening ceremony of the trade event.

The province will purchase Taiwanese products worth 6.66 billion U.S. dollars and invest 40.86 million U.S. dollars in Taiwan, he added.

The 1,000-plus strong Guangdong delegation led by Governor Huang Huahua arrived in Taipei Monday.

Guangdong hopes to seize the businesses opportunities presented by the Economic Cooperation Framework Agreement (ECFA) signed between the two sides across the Taiwan Strait in late June, Huang said at the opening ceremony.
