SHENZHEN, March 25 (Xinhua) -- A delegation from Taiwan's Kaohsiung city led by mayor Han Kuo-yu Monday signed agreements with four companies from Shenzhen, Guangdong Province, to sell 200 million yuan (29.8 million U.S. dollars) worth of agricultural and processed products to the latter in the next four years.

Han described his trip to Shenzhen as "short but fruitful," saying he was looking forward to more people-to-people exchanges between the two cities in the future.

The delegation also visited Yantian Port, the Han's Laser company, the Tencent company, and the administrative service hall of Nanshan District, in Shenzhen Monday.

Han expressed the hope to expand cooperation with Shenzhen in agriculture, economy and trade, sports, culture, exhibition and other fields in the future.

When he was asked to comment on the Democratic Progressive Party's criticism of his ongoing visit, Han said he did not worry about or fear verbal attacks.

"We hope that the Taiwan residents can keep their eyes open so that they can tell right from wrong. Politicians should serve the people."
