Shi said in a radio program that it is nice of government to expand “Return2HK” to other provinces of China. He suggested that a “business bubble” should be launched, based on the concept of “travel bubble”.

Shi continued and said that his idea of “business bubble” was to allow manufacturers’ drivers with licenses of both Hong Kong and Mainland, who are fully vaccinated, to return to factories in Mainland point-to-point without undergoing quarantine.

Shi believed that the idea would boost the businesses of Hong Kong’s manufacturers and it would be convenient for Mainland authorities to trace drivers’ whereabouts.

Wong Kwok, chairman of the Hong Kong Federation of Trade Unions, also welcomed the new arrangement of “Return2HK”. He added that the Federation received over 20 inquiries from Hongkongers who are currently at Mainland, as soon as the government made the announcement yesterday.

Yet he pointed out that only those who have desperate needs to return to the city will participate in the scheme, before quarantine is exempted in both areas. Others are expected to observe the progress of the scheme.

Wong hoped that the government would discuss with relevant authorities so that vaccinated Hongkongers would be exempted for quarantine in both Hong Kong and Mainland.

The government could also shorten the length of quarantine to 72 hours for returnees from China, to encourage citizens to get their jabs and attract Hongkongers in Mainland to come home, according to Wong.
