Thankfully no one belives China anymore. The media will always try to cover for them but the people know who is responsible for this virus. Even if they think its a natural virus they still blame China for keeping it secret for two months.

China wants to be seen as "clean" so countries open up borders and then China can ship out infected people again.

I would just lockdown China for a year or two. Bar travel to and from the country. Then bar any country that has opened its borders to them again.

But then again China needs to be locked off from the world regardless if it's telling the truth or not. As they will just do what they did again.
