The "China-Italy Extradition Treaty", signed in Rome in 2010, officially took effect on Sunday.

The treaty is aimed at curbing the escape of Chinese corrupt officials and to push China's foreign judicial cooperation to a new level.

Sun Ang with the Ministry of Foreign Affairs elaborates on the treaty.

"These successful cooperation cases not only help arrest the criminals involved but clearly show to the fugitives and those attempting to flee that there is no 'safe haven' for them in the world."

Another treaty between the two countries on criminal and judicial assistance took effect this August.

Based on the two treaties, both sides have an obligation to help each other with investigations, recovering criminal earnings and repatriating fugitive suspects.

China has signed a total of 121 bilateral extradition and judicial assistance treaties since 1987, covering 66 countries all over the world.

The "Sky Net" campaign launched in April is based on those treaties.

As of the end of November, Chinese police have repatriated a total of 738 fugitives from overseas in the campaign.
