BEIJING - The Obama administration should show sincerity in anti-corruption cooperation with China and stop parochial calculations.

On Sunday, the US government made a regrettable move by ordering the Chinese law enforcement personnel in the country for the "Fox Hunt" operation to return home immediately.

Regrettable is such action as China's operation is legitimate and has been approved in bilateral agreements reached earlier this year.

"Fox Hunt 2015," which targets corrupt officials of government departments and state-owned enterprises, is an important effort of China to crack down corruption.

The global law enforcement operation can serve as a great deterrent to corrupt Chinese officials, as it makes it clear that those officials have no place to hide.

Corruption is not only a serious problem in China, but also in the rest of the world. And in a world which is more and more connected, countries should take coordinated efforts in fighting corruption.

Although there is no extradition agreement between the United States and China, the two countries actually have already agreed on anti-corruption cooperation.
