I would say the answer is, absolutely. This is not new. China has never accepted these alliances. It may have been quieter about its opposition, particularly after 1998-99, when it got push-back from the United States about its criticism, but it has always opposed these alliances. It's constantly sought to probe them, undermine them and split American allies off from the United States, and even from one another. There is nothing new, I would say, in that regard. What is new is the current American administration, which has also called into question NATO, at least, and has not worked nearly as effectively as it could have to bolster the alliances in East Asia and other parts of the world.
