The UK has been clear that, since March 2021 and following Beijing's imposition of the National Security Law on Hong Kong, China has been in an ongoing state of non-compliance with the Sino-British Joint Declaration. The Joint Declaration is a legally binding, UN-registered agreement that remains in force, and we continue to monitor its implementation through our Six-Monthly Reports on Hong Kong. We have consistently called on China to honour the commitments it made to the people of Hong Kong.
