Chinese Premier Wen Jiabao promised that the country would take actions to improve school bus safety on Sunday, a day after China saw its second terrible school bus accident in November, 2011.

“School buses should be safe mobile campuses(校园) for students,” the premier said at a national meeting on women and children, “Society(社会) should remember in mind that children should be the first to enjoy all kinds of social caring and the last ones to suffer from any disaster.”

School buses have become a hot topic in China since the deaths of 21 people, including 19 pre-school students, in a traffic accident between a truck and a school-owned minibus in Gansu province on Nov. 16, 2011. The nine-seat minibus was carrying 64 people at the time of the accident, according to the reports.

The second accident, in which a school bus in the northern province of Liaoning rolled over on Friday, left 35 people injured, according to China Daily.

“In recent days, a series of big accidents involving school buses has led to great anger among the people. These accidents have also made me uncomfortable,” said Mr Wang, an old teacher from Jiangsu. And he also thought that school bus safety must become a serious problem for schools and the government.

Premier Wen has already asked the government to develop new safety standard (标准) for school buses and made sure to help local government with safe buses for school-age children.
