The choice the government is taking now is experimenting with different methods on each of the provinces to see if they could keep the severity and spread of the virus to stable levels, then do a cost/benefit analysis on whether to continue with their strategy or pursue a different one. Unlike the Western style of lifting all restrictions and letting it rip within their population, which has big economic and social cost on the population.
And yes its expected they'll write something like that, their media is paid by those companies to do misinformation/downplay on the effectiveness of other vaccines, while overexaggerate their own. If we use their own metrics, then South Korea shows why Pfizer and Moderna doesn't work and that they should approve Sinovac and Coronavac.
