The Hong Kong Special Administrative Region government and France signed the Immigration Cooperation Protocol Friday.
The protocol was signed in the presence of HK Secretary for Security Ambrose Lee and visiting Minister of Interior of France Nicolas Sarkozy.
"The protocol, which enters into force with immediate effect, enables the two services to raise the level of cooperation through closer bilateral contacts, experience sharing and information exchange," a spokesman for Hong Kong's Immigration Department said.
"We warmly welcome the conclusion of the protocol with France, which reflects the determination of the two services to work more closely and cooperatively to tackle immigration problems of common concern, and opens the door for greater Hong Kong-France cooperation on immigration fronts," the spokesman added.
The Immigration Department has signed similar protocols with Portugal, Belgium and Finland.
The French minister of interior had paid a visit to Beijing and signed an agreement on enhancing cooperation between Chinese and French police with Chinese State Councilor Zhou Yongkang on Thursday.
