Frontier Closed Area

The Frontier Closed Area, established by the Frontier Closed Area Order, 1951, is a border zone area in Hong Kong, extended inwards from the border with Mainland China. For anyone to enter the area, a Closed Area Permit is required.
Established to prevent migrants from Mainland China and other illegal activities, the closed area is fenced along its perimeter to serve as a buffer between the closed border and the rest of the territory. Developments are tightly controlled within the area, leading to less construction and causing most of the area to become a natural habitat for animals and plants.
History.
The area was established under the Frontier Closed Area Order in June 1951 by Hong Kong Governor Alexander Grantham.
In order to fight gun smuggling during the Korean War, a curfew was put in place in the closed area in 1952. Villagers had to stay inside from midnight to 4:00 am unless they acquired a special permit from the police. Following the war, the curfew was retained to help control illegal immigration.
A simple chain link wire fence was built at the border between 1950 and 1953. It was later described as "flimsy" in the "South China Morning Post", in that groups of refugees could press it flat simply by leaning against it.
The boundaries of the Frontier Closed Area were adjusted under the Frontier Closed Area Order, 1959, gazetted on 20 February 1959.
By 1962, thousands of illegal refugees were attempting to enter Hong Kong each day. In response, a second, more robust fence, made of Dannert wire, was built slightly south of the original fence in May 1962.
Under the Frontier Closed Area (Amendment) Order 1982, gazetted on 24 June 1982, the area was expanded by four square kilometres in western Mai Po, near Pak Hok Chau.
The frontier area was further adjusted with the Frontier Closed Area Order 1984, gazetted on 7 September 1984. The amendments reflected the relocation of the Man Kam To Control Point, and also completely excluded Lei Uk Village from the closed area.
Border patrol duties were transferred from the British Army to the Field Patrol Detachment in October 1992.
The nighttime curfew in the Frontier Closed Area was discontinued from 1 August 1994. Secretary for Security Alistair Asprey stated this was to "balance individual rights and the need to combat illegal immigration".
Closed Area Permit.
A Closed Area Permit is a document issued by the Hong Kong Police Force to allow for people with ties or residence in the area to travel in and out of the Frontier Closed Area. Visitors to the Mai Po Marshes are also required to apply for a Mai Po Marshes Entry Permit from the Agriculture, Fisheries and Conservation Department.
2006 reduction proposal.
Reduction of the FCA from was proposed in September 2006 by the government. According to the adopted proposal, most of the FCA will be de-designated and the FCA only maintained around border crossings.
This will be made possible by the building of a secondary fence along the border roads, such that most villages in the FCA will fall outside of it without having to compromise the integrity of the border. A planning study was to have been undertaken by the Planning Department.
Depending upon the progress of the new fence, the reduction will be implemented in four stages with scheduled completion in early 2015. Members of the public will no longer need to obtain a permit to enter the excluded areas.
First phase of implementation.
On 15 February 2012, areas around Sha Tau Kok (but not the town itself), as well as Mai Po, were taken out of the Frontier Closed Area, opening up of land for public access. A checkpoint on the original perimeter, at Shek Chung Au, was decommissioned and its functions taken over by a new checkpoint outside of Sha Tau Kok.
Environmental issues.
Environmentalists and the WWF have pointed out that the proposal will have negative impacts on the ecology of the excluded areas.
Border Road.
Border Road () is a road along the south bank of Sham Chun River, and the northernmost road in Hong Kong. Since January 2016, it is amongst the only remaining places within the Frontier Closed Area (along with an area around and within parts of Sha Tau Kok). Currently it is used for patrolling purposes only and public entry is forbidden. It starts from Mai Po Nature Reserve in Yuen Long and ends along Lin Ma Hang Road.
