When major disasters occurred, Zhang, as director of the State Council Work Safety Committee, would set out for an accident site immediately to oversee rescue operations, no matter how far away the site was and no matter how tough the conditions were.
On March 28, 2010, the Wangjialing Coal Mine in north China's Shanxi Province flooded, but Zhang reached the mine that very night to supervise rescue work. In the end, 115 miners were pulled out of the shaft alive in a "miracle" rescue.
Again, after the fatal high-speed train crash in the eastern Chinese city of Wenzhou on July 23, 2011, Zhang arrived at the scene quickly and put saving people's lives as the top priority. When he saw the wreckage of train carriages piled in a pit, he gave a clear instruction that no one should bury the wreckage, and the accident site and the train carriages should be properly preserved in order to guarantee investigation and analysis of the cause of the accident.
A string of successful rescue operations has demonstrated Zhang's personal quality of responsibility and his talent for handling complicated issues.
As vice premier, Zhang has made many overseas visits. In July 2011, he led a delegation to visit the Democratic People's Republic of Korea (DPRK). He attended the commemorative activities of the 50th anniversary of the Treaty on Friendship, Cooperation and Mutual Assistance between China and the DPRK. He also visited his alma mater, Kim Il Sung University.
