China maintains that its dynamic zero-COVID policy will help defeat the pandemic, and contribute more to the world's battle against it. This comes as some are questioning the policy. Beijing reiterates that the measures are not aimed at zero cases, but at prevention and control methods that come at the lowest costs in terms of people's lives and livelihoods. Beijing says the policy is based on science and has been effective in China, which has one of the lowest COVID-19 infection and death rates in the world.
