What Singapore is doing with green lanes, bilateral and unilateral reopening is putting its chess pieces in position to regain its air hub status and attractiveness for investors and visitors alike. Its next chess piece is regaining its status as one of Asia’s top venues for international meetings, a market that contributes $2.8 billion (S$3.8 billion) to Singapore’s economy before the pandemic. This is beginning at home, where on Monday, 150 participants of the Singapore International Energy Week piloted a rapid or antigen test on-site. All tested negative. The result, valid for 24 hours, was delivered via mobile, which gained them the entry badge to the event. Antigen tests deliver results in minutes and are cheaper — said to be around $22 in Singapore — compared with a PCR test, which costs about $147 but is more accurate.Raini Hamdi (Skift)
