That is just the the tip of the Iceberg. There was a trade war before that. Then came sanctions over the virus.
Then there are rumors, and I stress - rumors -, of political infighting among the CCP. Many in the party not on Xi's favorite list are trying to get their money, and themselves, out of China.
Com'on! Everybody knew the Chinese would have to be first!
Otherwise, they might take offense. They often Boycott even if they think China has been offended in some way.
Almost all of the Asean countries have better Covid statistics than China an they are all still blocked off.

Still, it is Thai Tourism's biggest customer.
I think they should broaden their tourists base though.
