Seriously?... in protest to such cold shoulder treatment. Think about it, such low-grade access won't teach the PLAN anything new anyway.
They get invited for the first time ever. And they are involved in maritime interdiction missions, and a 1st ever Hosptial ship exercise?
That's not the "cold shoulder" in the least. The cold shoulder would be to not invite them at all...or when inviting them to have them sit in port in Hawaii and observe only, or to go out but stay 20 miles or more out of the way.
Instead, they are going to be a part of a Joint Task Force and conduct realistic exercises with those forces.
I would hope most Chinese would recognize and welcome the opportunity to be a part of the largest and most involved multi-nation naval exercises on earth, and therefore put their best foot forward.
We shall see which combatants they actually send...but I am willing to bet it is not Luda class.
A Type 054 and either 112 or 113 at the least.
A Type 054A and a Type 052B or "C" or Type 051C at the best.
