From Merriam Webster:
Sorry:
—used to express polite regret
—used to introduce disappointing or bad news in a polite way
So my understanding for Jimmy's sorry is : (1) he regrets for doing this
because it caused him some troubles; (2) he feels a shame or disappointment
that his talk was not taken as a joke by Chinese people.
Did he ever acknowledge this is a fault and mistake? Did he ever admit what
he said is WRONG. DId he ever realize what he said is totally unacceptable
and inappropriate ? NO !
Now I wonder why some of us would accept his "sorry" already...
