It is difficult to name a country that has "defeated" COVID. This video is from one of the best responses if you believe the lies the Chinese government pumps out about their COVID case counts. The situation today remains the same as the situation in March 2020 - anyone who doesn't die quickly of other causes is going to get COVID. The only surprise the entire way through the pandemic is they managed to rush a vaccine into mass production in ~12 months rather than a couple of years (very much a record!).

Even with that good news the damage from the lockdowns may not have been worth it, the world is re-emerging into a rather unstable environment with a lot of nervous people that looks ripe for WWIII. It is debatable whether the government interventions were actually a good idea, we don't have the full picture of what the costs were. I'd still rather have seen them pushing out honest, current information and then letting individuals make decisions for better or worse.
