Shanghai Mayor Han Zheng paid a four-day visit to Taiwan from April 6 to 9. He was the first mayor of the mainland's four municipalities directly under the jurisdiction of the Central Government to visit Taiwan.

Promoting the Shanghai World Expo, which will soon open on May 1, was at the top of Han's agenda during the trip.

While in Taiwan, he made extensive contacts with people from all walks of life, visiting schools and hospitals and meeting local residents. He also attended the Taipei-Shanghai forum where the two cities signed memoranda of understanding on cultural exchanges, tourism and environmental protection.

Han, 56, became the mayor of Shanghai in 2003 and was re-elected for a second term in 2008.
