A day earlier, the city-state declared a central region, comprising the districts of Tanglin, Newton and Orchard, where the Ministry of Foreign Affairs, the US Embassy, and several large hotels are located, as a "special event area" from June 10-14.

In its online gazette, the Singaporean Government said the amended zone included Sentosa and an area of the sea stretching more than 1 km off its southwestern shore.
A smaller area in the centre of the island that includes the Capella hotel, which media have mentioned as a possible venue for the June 12 talks, will see greater presence of police.
The government has said police would make stricter checks of people and personal belongings and items such as public address systems and remotely piloted aircraft system would be prohibited.
This is the second time Singapore has declared the “special event area” under the Public Order Act since it was revised in April 2017. The first was during the 32nd ASEAN Summit.
