A long delayed travel bubble between Hong Kong and Singapore will begin on May 26, the two cities said, as they moved to re-establish overseas travel links and lift the hurdle of quarantine for visiting foreigners.

The bubble between the two Asian financial hubs had been slated to begin last November but was suspended after a spike in coronavirus cases in Hong Kong, according to Reuters.

The scheme will start with one flight a day into each city, with up to 200 travellers on each flight, Hong Kong's Commerce Secretary Edward Yau and Singapore's Transport Minister Ong Ye Ku said at simultaneous press events.

Those wanting to travel from either city must test negative for Covid-19 before departure and on arrival. Hong Kong residents can also only fly to Singapore at least 14 days after they have had two doses of Covid-19 vaccine.
