New COVID requirements in force January 9, 2023 to January 31

[Blueskytoday]

Last couple days...Chinese who had negative covid test 48 hours prior to boarding flights, arrived at Incheon Korea Airport....All passengers given on the spot covid test on arrival...up to 1/5th of all arriving Chinese tested POSITIVE...(to me this means, the vaccines the Chinese receive are no good, OR, the tests they give/take are not at all world class standard.....OR they come with phony test certificates.........something very wrong here..
