China will work with other countries to build a wider and tighter net of international anti-corruption cooperation, Foreign Minister Wang Yi said Sunday.

Anti-corruption is a never-ending struggle and China would never relent its efforts of overseas hunting for suspects and recovering of their illegal assets, so that "even the most cunning fox will have no place to hide," he said at a press conference on the sidelines of the annual session of the National People's Congress, China's top legislature.

China launched the Operation "Fox Hunt 2014," bringing back a large number of corrupt officials and economic crime suspects who have fled the country. The campaign upheld sanctity of laws and social justice, Wang said.

China has concluded a total of 91 treaties on extradition and criminal judicial assistance, he said. "We would like to conclude relevant treaties and agreements with more countries."

He noted that an anti-corruption declaration was adopted during the Asia-Pacific Economic Cooperation meetings in Beijing, and a cross-border law enforcement network was set up.

"Our cooperation with relevant countries in the law enforcement is becoming more smooth and effective," he said, appreciating the support given to China by other countries.
