UNITED NATIONS, May 23 (Xinhua) -- China is a champion of pragmatic cooperation under the UN Convention against Corruption and is grateful for the international support it received in hunting down corrupt criminals, a Chinese anti-graft official said here Wednesday.

Due to international support and collaboration, China's Operation Sky Net was instrumental in having 4,058 corrupt people repatriated, including 52 on China's 100 most wanted list, from more than 90 countries and regions, said Zou Jiayi, commissioner of the National Supervisory Commission of China, on the 15th anniversary of the Convention.

The operation, initiated in 2015, targets corrupt state functionaries who have fled China with their ill-gotten wealth.

"We are grateful to these countries for the cooperation they've rendered," she said, pledging to keep up the momentum and make renewed and unrelenting efforts with a view to achieving long-lasting results with the launching of Operation Sky Net 2018 this April.

In addition, Zou said China is among the first countries to sign and ratify the Convention and in recent years has worked in earnest to promote compliance through amendments to the Criminal Law and the Criminal Procedural Law as well as the promulgation of the Supervision Law and Anti-Money Laundering Law.

The legislative efforts aimed to ensure that the main provisions of the Convention are well grounded and rooted in the Chinese legal system, she said.

Moreover, Zou noted, while receiving international support in its anti-corruption campaign, China has also contributed "Chinese solution and Chinese wisdom" to the globe governance in this area.

"China will uphold the vision of global governance featuring consultation, contribution and sharing," she said.

Also, China will "adhere to the three principles of zero tolerance, zero loophole and zero hindrance in expanding and deepening international cooperation," she added.
