The surrendering to justice of China's most wanted fugitive Yang Xiuzhu on Wednesday is a major achievement for the country's anti-corruption efforts.

It also indicates that China's law enforcement cooperation with other countries in tracking down and apprehending its corrupt officials, wherever they flee, has entered a new stage.

Yang, a former vice-mayor of Wenzhou in East China's Zhejiang province, is accused of embezzling more than $37 million and ranks No 1 on China's most-wanted list of 100 fugitives publicized in April last year, all of whom are subject to Interpol "Red Notice" arrest warrants.
