LONDON - A spokesperson for the Chinese Embassy in Britain said on Thursday that China firmly opposes Britain's offer to provide more privileges for Hong Kong residents holding British National (Overseas) passports and reserves the right to take corresponding measures.

If the British side makes unilateral changes to the relevant practice, it will breach its own position and pledges as well as international law and basic norms governing international relations.
