In April 2015, US Homeland Security Secretary Jeh Johnson met Chinese Public Security Minister Guo Shengkun in Beijing, and they agreed to strengthen cooperation in law enforcement.

They agreed not to provide shelter for the other side's fugitives and would try to repatriate them in accordance with law. Specifically, Johnson also promised to actively support China's "Sky Net" and "Fox Hunt" operations, which aim to bring back corrupt officials.

So the US government's decision to force China's law enforcement stuff to leave the country obviously reveals that Washington lacks sincerity and has failed to translate its words into action.

Some analysts even say that the United States is reluctant to repatriate those corrupt officials for the sake of their money of course.

Therefore, the United States, as a country that often stresses the rule of law, should clarify the issue and by no means become a safe haven for Chinese criminal suspects.

Washington should display necessary sincerity in future law enforcement cooperation with China in order to dispel such suspicion.
