Security measures have been put in place on Saturday as Singapore prepared for the arrival of US President Donald Trump and North Korean leader Kim Jong Un ahead of their meeting next week.

Security around the St Regis and Shangri-La Hotel near the shopping area of Orchard Road was tightened as the two luxury hotels are said to be where Donald Trump and Kim Jong Un will be staying during their visit. Neither of the hotels have confirmed media reports.

Kim is expected to fly into Singapore's Changi airport on Sunday (June 10) ahead of the high-stakes summit with Trump. Kim will meet host Singapore's Prime Minister Lee Hsien Loong upon arrival.

The Singapore government has announced to increase security and said police will make stricter checks of people and personal belongings and prohibited items such as public address systems and remotely piloted aircraft system in the area.

Kim has said he is committed to the high-stakes summit with Trump, the first such meeting between a North Korean leader and a sitting US president.

The summit announcement came in March after several months of unprecedented cordial diplomacy between South and North Koreas, which had been adversaries for decades.

The United States, which has substantial presence in South Korea, was on a war footing with the North over Pyongyang’s nuclear and missile programs.

The development resurrected hopes that Trump and Kim could try to find a solution to the crisis on the Korean Peninsula that has escalated over the past year.
