No, potentially not, depends if they ratchet up what they are doing to see what they can get away with and/or the response made, if that is what they are doing.

Maybe. I think this could be China tending towards a more provocative way of doing things though, taking a page out of Russia's recent MO of how to behave.
Caught several times in a few days, seems very careles unless they wanted to be caught, in which case its not the same, or it's not the Chinese, in which case it's not the same.
