A top level delegation led by two ministers will hold talks in Beijing on Tuesday about the cross border notification mechanism, the Chief Executive CY Leung announced.
The Justice Secretary, Rimsky Yuen, and the Security Secretary, Lai Tung-kwok, will fly to the capital on Tuesday morning. They will be accompanied by the heads of the Immigration and Customs Departments, as well as the acting police chief.
They will come back to Hong Kong in the evening on the same day and report to the media about their work on Wednesday.
They will discuss with officials of the Ministry of Public Security and the Hong Kong and Macau Affairs Office ways to improve a mechanism under which mainland authorities must notify Hong Kong government about the detention of its residents on the mainland.
Last month, the Chief Executive vowed he would follow up on the matter of the alleged kidnapping of the Causeway Bay booksellers with the central government.
The CE said the review of the mechanism would be comprehensive. He added that officials would also listen to a report by mainland authorities about the Lam Wing-kee case.
Lam, one of the five staff of the bookstore, claimed that he was kidnapped on the mainland and kept in illegal detention for selling books critical of Beijing leaders. There was no communication about his detention from the mainland authorities, raising charges that Beijing had ignored the "One Country, Two Systems" principle.
Lam had claimed that he had been taken and detained by members of a "Special Investigative Unit", but the Chief Executive said he's never heard of the term. He also fell short of telling reporters what changes he's hoping to see, and when the review will be completed.
Lam also said his colleague Lee Bo was taken away from Hong Kong against his will. But Lee has denied this.
