An announcement on the launch date for the travel bubble is expected in early July, following a review by both sides.
The latest developments come in view of the COVID-19 epidemic situation in Singapore, which has been stabilizing since early June, the Hong Kong government said in an announcement on Thursday.
Both consider that it is prudent to keep the developments under review to ensure the epidemic situation is sufficiently stable before deciding in early July on the way forward for the ATB, the announcement said.
The travel bubble between two business hubs, planned since October 2020, has been beset by numerous delays.
On Thursday, Singapore also announced the easing of curbs to control the spread of Covid-19, to take place from June 14.
The city-state brought back stricter social distancing measures in early May amid growing community infections, but new cases have since stabilized in the low single digits.
