Hong Kong’s leader said on Tuesday that Britain had breached an agreement with China by expanding immigration rights for Hongkongers holding British National (Overseas) passports, and it would be a “matter of course” for the other party to retaliate.
But Chief Executive Carrie Lam said she was not aware of any specific plans to do so.
Her comments came after lawmaker and Executive Councillor Regina Ip suggested that the Hong Kong government adopt China’s nationality law, which would ban dual nationality.
“The issue of nationality is a sensitive matter, and many citizens were concerned about the discussion before the  handover,” Lam told a press conference. “That’s why, because of historical reasons, the Chinese and British governments had a consensus on how to handle the British National (Overseas) passport.”
“If someone has now unilaterally deviated from the consensus, it would be a matter of course for the other party to take some action.”
Lam added that her government had not proposed any measures regarding the issue of BN(O) passports, which until recently did not allow holders the automatic right of abode in Britain.
Ip wrote in a column for the South China Morning Post on Sunday that it might be time for the Chinese government to stop allowing Hong Kong people to hold dual nationality.
“The new route to citizenship offered by the British government is not only a slap in the face of the Chinese authorities for enacting a national security law, but also fraught with adverse implications,” she wrote.
Ip told Commercial Radio on Tuesday that it was time for would-be emigrants to choose. “It’s obvious that they don’t want to be Chinese if they would endure six years of ’emigration prison’,” she said, referring to the time it will take to acquire full British citizenship.
She added that since Taiwan is a part of China, people who emigrated there should not be included in such requirements.
Following China’s imposition of the national security law on Hong Kong last June, Britain announced plans to expand visa rights for hundreds of thousands of people eligible for BN (O) passports. From January 31, holders can apply for a special visa to stay in the UK to work or study for five years before being allowed to apply for settled status.
After their sixth year they can apply for British citizenship.
Following the UK government’s announcement last July, Beijing threatened to cease recognising the BN(O) passport as a valid travel document, and said it reserved the right to take further action. The Hong Kong government said it would “fully cooperate” with Beijing.
