Hong Kong does not recognize dual nationality; UK citizens advised

The UK FCDO updated its travel advice for Hong Kong, emphasizing that Hong Kong does not recognize dual nationality and does not recognize the BN(O) passport as a valid travel document or proof of identity. If you hold both British and Chinese nationality, you may be treated solely as a Chinese citizen even if you enter on a British citizen passport, and the British Consulate-General may not be able to offer consular assistance. If you have formally renounced Chinese citizenship, carry evidence. Additionally, be aware of regulations on e-cigarettes and illegal drugs including CBD.
